I am quite annoyed by the people who don't see the issue with eSim because "they never had an issue" with it. It's like having one murder down your block and stating that you don't see the issue because nobody attempted to murder you so far. ESim are backed up as part of iCloud backups, had one dodgy carrier in Europe (Lyca) who never activated my eSim so I switched back to a new carrier but I had to get a transfer authorization from Lyca. Guess what , since I was no longer a customer I was sent to hell by their customer support. Best joke that it was impossible to remove on my iPhone. It was part of the backup, a reset attempt did not solve it so I had to drive 200km to an Apple store to get a hard reset and the Apple genius advising me against restoring my data "otherwise it would retrieve the faulty ESIM back in your phone" !!!
You can’t actually backup an eSIM. If you could, they would be easy to clone. I know Apple uses that terminology, but that isn’t what is happening in the background. Same with transferring an eSIM. A new one is issued each time.
Isn't that just semantics? It's tied to the same phone number, and I assume the generation of a new eSIM invalidates any old one (as happens with my carrier.) It's essentially backed up, even if it's just a (carrier, number) pair. If the Lyca account is trashed, the rest is just an implementation detail.
But it's not, because some carriers explicitly don't allow eSIM transfers, or reuse of the initial QR code, or even the forced generation of a new eSIM without either customer support manually revoking the previous one, or deleting it yourself from the old device.
I think the problem here is: there's no consistent regulation on how a replacement eSIM can be provisioned on a new device.
Is the fact that you don't actually own a game you bought on steam, or a movie you bought on itunes (eg. if either of them went under, or you got banned) also "just semantics" and "implementation detail"?
eSIM profiles are not backed up, as the key never leaves the Secure Element. What might be backed up is a token allowing the reissuance of a replacement eSIM by the carrier.
I occasionally buy travel data, and 3 of probably 8-ish instances had me on the phone with support for at least 20 minutes (and once an hour) to make an esim work. Perhaps the problem is android. But I've never had that experience with a physical sim. :shrug:
Did this yesterday on Android when arriving into Indonesia. While my wife waited in immigration, I used the Smart Gates. I downloaded an eSim via Airalo in just 90 seconds, providing me with enough data to send her a "good luck" message and let her know I'd see her at the hotel if she cleared immigration.
Turns out women can be independent and don't need 24/7 supervision. If you fly often, there are situations where it's easier to stick together and situation where it's better to go independently. Especially if one of you can take the kids the faster way.
Traveling with kids is a different story, but there’s no mention of that here. Most people wouldn’t jettison a regular friend at passport control, text them “good luck” and head off to the hotel. This guy did it to his wife.
Well, if its related to the original poster, then how do you know it is their first time in indonesia? :)) Most likely, :)), it is Bali, and for sure, you can leave wifey alone.
Fair enough. Still rather odd thing to write without at least acknowledgment of this being unusual — I guess this is what had people somewhat triggered, because they made it sound as if this was a natural thing to. But we digress.
To clarify, I went to the hotel, she got through (eventually) and went to a conference. I collected her luggage. We met back at the hotel later that evening.
Is this because of an older version of iOS or specifically because of the shitty carrier? I can add and remove esims from my iPhone. I just recently added one for my new 17 Pro Max. It prompted me to login to Verizon and it "just worked". There is an option right there to delete the Verizon esim. Nothing restricted or difficult about it.
Yeah, eSIMs are built for high trust locations. I just use Google Fi and they’re pretty decent about it all. This whole “switching a carrier” business is kind of pointless busywork I don’t do any more.
Odd how it works out, but my work Pixel 8 on Google Fi forgets its eSIM about once every three Android updates. Usually takes 15 minutes to an hour to work itself out, with no indication as to what happened or why. Turned me off completely from eSIM-only devicess and Google Fi for personal use.
Hell, as I write this my on-call phone just notified me that its eSIM isn't valid. Good thing I'm not on call yet!
Classic Google. I’ve used the eSIM on iPhone flawlessly across numerous countries for 8+ years now. It’s typical that their stuff wouldn’t work on their own hardware.
> I am quite annoyed by the people who don't see the issue with eSim because "they never had an issue" with it. It's like having one murder down your block and stating that you don't see the issue because nobody attempted to murder you so far.
TBH that's most people on most subjects.
First one that comes to mind:
"I'm an honest citizen and never did anything wrong and never had a bank account frozen, hence it never happens to honest citizens who did nothing wrong".
You sound like you had a murder down your block and you are scared (understandably), but if nobody else anywhere had any murders you should understand why they aren't scared.
My carrier lets me issue esims myself on their website. I can login, get a QR code, and scan it on my phone and the service just starts working.
Personally I find this preferable to having to go to a physical location, and the fact that I can issue a new sim card to myself anywhere in the world has been very helpful.
Technologically, eSIMs are pretty nice. The electrical interface between the phone modem and the eSIM is the same as with a real SIM card, and the eSIM can run the same applications as a real SIM card, so at this point you can buy smartcards that can be swapped between devices and run eSIM applications. esim.me, 9esim and the "sysmocom eUICC for eSIM" (seems to be the most open/friendly at this point) are some of the options. Most of them offer an app for management, but there are also standardized interfaces.
SIM cards have always been secure elements that the provider trusts. With an eSIM, you can already own that secure element and the provider can provision it with their application. You can even have the applications from multiple providers on the same physical secure element.
The major advantage is now that the expensive and time-consuming part of provisioning a new mobile service (sending out a physical SIM card) can be replaced with a few standardized API calls. This is cheaper (which makes the extra cost some providers charge for an eSIM look quite silly) and a lot quicker, which enables new business models for short-lived cell connection services.
A world where all cell service providers offered eSIMs would be slightly nicer. But manufacturers removing the option of swapping the secure element is very annoying at the same time.
> The major advantage is now that the expensive and time-consuming part ... is ... sending out a physical SIM card
For the carriers I can see that. Especially the part where users can't move their esim without carrier cooperation. That grants telcos (and sometimes handset manufacturers) additional control over users - control that they don't get with physical sim.
And physical sim save me time and money. I get a new SIM each month. It's 1 min to swap it and update my forwarding #. Service is reliably cheap.
When I need my sim elsewhere (ex:5g router), I just move it.
> The major advantage is now that the expensive and time-consuming part of provisioning a new mobile service (sending out a physical SIM card)
I don't know, choosing service package, signing paperwork, identifying and other KYC stuff (tens of minutes) for me was always much more time-consuming than the few seconds of reading the barcode(?) from a new SIM card and giving it to the customer (or putting it into an automatically addressed envelope).
I can't see any advantage of eSIMs except that it makes harder to change providers what they of course really like.
(Anyways the security of the whole PTSN is a joke and publications about cracking cell networks, why SIM cards are even a thing? I would suspect an customer-id@service-provider.country and a password would work, too. Maybe with a zero-knowledge password proof.)
They are incredibly handy when you are traveling abroad, you don't speak the local language fluently, you want cheap data, you don't want to study 100 different prepaid plans from 10 different local primary and MVNO carriers to figure out the best offer, you don't want to wait for the shops to open because your flight landed late at night, and you don't want to scan your passport and send it to the carrier for verification and wait for hours for approval (yes, in many countries, KYC is required even for prepaid SIMs). I've lived that experience and I can't say I miss it.
Yeah, basically people here think that their experience is the only experience there is with phones. I wager not that many people are actually physically going to stores in many markets anymore like this commenter, and definitely next to nobody is switching their SIM cards literally every month like a sibling commenter is doing, but for people like me who live and travel abroad, eSIMs have been great.
Really? I live in Japan, eSIMs made it very easy for me to switch carriers 3 times when I was shopping. Just had to click the “agree” checkbox in the ts and cs for each carrier when I switched, provide the transfer code (which is always in an easy to find place in their management dashboards), and then plug that into the form when signing up for the new carrier. Then my butt did not have to budge from my couch as the eSIM was provisioned and my old service was cancelled automatically. Definitely beat schlepping it to the physical stores of each carrier in ye olde times.
The spec allows carriers to disallow removal of an eSIM, to allow for subsidized phone business models (in other words: this change was demanded by the carriers). So you should blame the carrier, not the manufacturer that simply implements the spec.
It might be nice if manufacturers implement a HUUGE LOUD warning when enabling an eSIM that requires carrier authorization to remove though. Someone should put that in the Android bug tracker.
> The spec allows carriers to disallow removal of an eSIM, to allow for subsidized phone business models (in other words: this change was demanded by the carriers). So you should blame the carrier, not the manufacturer that simply implements the spec.
Gosh, that sounds pretty nuts if some $5 throwaway travel eSIM refused to be removed after a few days of use.
I think the major advantage for consumers is being able to securely ensure their cards never breaks and device restarts make their sim always available, no need for pin.
Even if someone steals your phone they can’t disable your SIM card unless you don’t have a pincode.
I’ve had a SIM card constantly fail and require me to put my pin to unlock it multiple times in the same day. If someone wanted to call me they would not be able to because I didn’t know it was off.
eSIM is also great for travel. There's a lot of competition on price and it's easy to check esimdb to find the cheapest carrier that meets your needs for a given trip. Download the eSIM in advance and you're good to go as soon as your plane lands
Unfortunately there's not much competition on providing low-latency data connections, so most travel esim providers don't advertise where their connections route through. It's not great when you're travelling and all your connections to local sites get routed through and geo-located to a different continent.
True but it can be an advantage as well. Some countries highly restrict what you van do on the internet and a roaming card bypasses that. For example UAE doesn't allow calls via WhatsApp but foreigners can do it fine this way, no need for VPNs even (though a foreign roaming kinda acts like a VPN in the geolocation sense)
I am currently traveling in the Philippines and used a cheap eSIM provider offering nearly unlimited data. The only problem was all the traffic was getting routed through China, and then I encountered a bunch of great firewall or geolocation restrictions. For example, Claude wouldn’t work because Anthropic doesn’t allow access to Claude in China.
Eep! I guess you do get what you pay for. I tend to stick with Airalo for that reason. It's more expensive, but there's also no monkey business like this.
Airalo definitely does not always have endpoints in the country they're selling the esim for - I contacted their support a year or so ago and their response then was that they explicitly do not give any IP address or routing guarantees or information.
What are you even talking about? eSIM for travel requires to be connected to internet and in the country when provisioning. With a SIM you just pop it in. It is however nice to be able to buy an eSIM without having to wait in line at the airport, but you get what you pay for. The airport SIM is better than the eSIM from generic provider, depending on your use case, like making calls in some countries
I like that my current phone can do both, and I'll hold onto it as long as I can. Why can't we just have both options? Why do we need to keep removing features to save 2mm of space inside the phone? Oh right, it's not really so much to save space, it's to make an extra $0.01 per phone they sell.
> We gave up the headphone jack. We gave up the microSD card.
Some people might have given it up. I personally own a Sony Xperia phone, and intend to buy another Xperia next year, which will almost certainly still have both. In fact Sony is the one manufacturer that returned to a headphone jack after having removed it for a while. It might be more expensive than the competition, but this is my voting with my wallet.
By a _substantial_ margin, because the best bang-for-your-buck strategy with smartphones for a long time has been to buy used or refurbished popular flagships for the last one or two years. As much as I like what Xperias are doing with a headphone jack and an SD card slot, the used market for them is almost non-existent. Even if you somehow manage to get a good deal, it will be even more difficult to find a good case and accessories like a reliable magnetic wallet, the market is just isn't there.
I myself have settled on using a Pixel with a headphone jack DAC dongle and an external hard drive.
There are some mostly reliable ones out there on the pricier end, but the catch is that they are almost exclusive to flagships. For the extra-cautious, some even have "Find My Device" compatibility baked in.
Most phones that cost less than ~300 USD still have a headphone jack and microSD slot.
I've never understood spending more than that on a phone anyway, you can't exactly use all that processing power on a phone operating system. Unfortunately some of the bad features from expensive phones have been moving down to the cheaper ones, like the destroyed screen that's missing its corners and has a hole for the camera in it for some reason.
I just bought a newer phone and was surprised to see even the ~$200 Samsungs were lacking a headphone jack. That threw them right out of contention, so I ended up getting a 2024-model Motorola (the 2025s were $50 more and reviews said they offered no meaningful performance boost).
I get it, but the quality of headphones with cords has gotten so bad that the male jacks wouldn't last more than a few months. My son has gone through an untold number of corded headphones because his school iPad is too locked down to use bluetooth ones.
You can spend a little more and get headphones with a replacable cord, and replace the cords if they get broken. Or maybe take the time to solder new connectors onto broken cords.
Budget phones are going to have different missing features for different people - for me the problem are that budget phones are all too large, full of software bloat, and receive poor software support.
If you're so concerned about camera quality ... buy a dedicated camera.
A 32 MP+ point-and-shoot starts at about $40, though goes up from there (to several thousand dollars for top models). As a bonus, it has an expected life far exceeding that of a smartphone.
Yes because I really want to carry around two devices including a crappy phone. The latest version of iOS supports iPhones from 2019 and Apple is releasing security updates farther back than that.
Do note that unfortunately any future devices by Sony are just phones by other manufacturers that are just Sony branded. Sony stopped their first party device manufacturing, so your mileage of the hardware might be wildly different in the future.
I've rocked pixels for a good while now, but the Xperia lineup has always been something I've really debated.
My largest concern is camera quality: obviously it is Sony, but if you wouldn't mind, could you elaborate on their camera 'stack' a bit (esp. in relation to pixel phones if you have first hand experience...).
I own an Xperia 5iii (so about four-and-a-half years old now), and I also own a Pixel 10.
The Pixel 10's camera is unequivocally better. The JPEG outputs are processed, 'Instagram-ready'. The output from the Sony camera even in JPEG mode is considerably more muted, neutral, and has less contrast. Note that this is not representative of newer Xperias' camera quality; I've heard they have improved considerably. I'm not too concerned because I hardly use my phone to take photos; I have a Nikon mirrorless for that.
Yes and their update policy really sucked compared to the competition while their price was the same or even higher. They've only fixed that recently but it was too late. This was the main reason I never got one.
Except 4G/5G does not work properly in Australia. :(
It is some carrier configuration bullshit or something like that. There may be a way to make it work, but it did not look guaranteed after reading dozens of pages on forums on the topic. I ended up retuning the Sony I tried whilst I could still get a full refund.
Phones used to be exciting. Now it is just frustrating because all the good features are gone. Headphone jack, sd card, fingerprint sensor on back, unlockable bootloader.
Nothing. But I want the SD card, dual sim plus eSIM, a headphone jack, a rectangular screen with a decent aspect ratio ideal for wide-format films and scrolling. I will fully concede that Sony's software quality has taken a hit in recent years; they used to be much better in 2016 or so.
Worse quality, latency, potential to lose one (or both) earbuds, having to faff with batteries and charging and cases (and charging the charging case) when I can just... plug it in, bam, music in my ears. The knotting is a small price to pay for the improved quality and convenience in every other way.
Something I read recently which I think is interesting food for thought:
Did ditching the headphone jack increase the number of people in public who just play their music / talk on speakerphone, because now the alternative is much more complex and expensive compared to simple 3.5mm wired headset?
Before proclaiming that Bluetooth is in fact simple and cheap, consider how your situation may differ from that of the perpetrators
My own memory and current experience on this point is that it used to be far more common than it is today.
I remembered there was a South Park episode where Cartman was being a stereotypical self-absorbed person walking around with their phone on speaker. I looked it up, and that episode came out in 2013. At the time, most phones on the market had a 3.5mm jack. Yet people not using headphones/headsets was an experience common enough to be turned into a joke in the show.
I don't think there's much correlation between 3.5mm jack availability and using a phone's speaker output in public.
"Simple" as you've used it is open to interpretation. I personally held on to wired headsets longer than most of my friends and family. You know what I don't miss, now that I've preferred wireless for a few years? Untangling the cable. Accidentally catching the cable on something and having an earbud ripped out. Picking lint out of the jack. Staying conscious of the length and positioning of the cable in the context of my own movements.
Other than the BT connection process, which is only complicated if you're fortunate enough to own multiple devices and headphones/sets to connect to them, wireless can be a lot "simpler" in actual usage.
I appreciate the counterpoint. The Cartman example is a good one. Also it's probably difficult to factor out the seemingly broken post-Covid social norms
One point I'll make is simplicity comes in many forms. Wired headphones can be dirt-cheap, they don't run out of battery, and I don't think they're as prone to getting lost
Cheaper yes, but the entry level for BT is still pretty accessible. Using Google Shopping, the lowest priced match for "wired earbuds" is $1.47. The lowest priced match for "bluetooth earbuds" is $2.46. In both cases, you hit a breakpoint of "this looks like it might possibly work for more than a few seconds" around $10.
The battery point is valid. Funnily enough, the last pair of earbuds I lost was a wired one. Myself, most of my headsets are over-ear, so they're a bit large to be easily lost. The form factor likely determines the loss potential more than the presence/lack of a wire.
The risk of losing one (or both) earbud is a real one. My ears don't tend to keep snug grip on the earbuds so they tend to get loose after I walk a little. With earbuds, this might just be my own singular piece but, there is also the chance that only one of the two would connect to your phone.
On the other hand, the cables get tangled together. I can't walk around with them because the cable gets stuck in the swing of my arms. Connecting them to the phone after a call had already started was a piece of cake though. With bluetooth, I never have my earbuds on when I actually need them and it's too much of a pain to take them out of my bag and connect them.
Whenever it is time to replace my current earbuds, I am gonna go for a neckband instead. It has basically the best of both, imo (I am not that sensitive to audio quality mostly) and the downsides aren't large enough (I'll think of the weight as a neck workout).
Then don’t buy headphones like that. I have AirPods Pro. But I also have a pair of $50 Beat Flex that if they fall out of my ear they just go around my neck. I use them when I travel.
I bought a pair of double flange doohickies to replace the standard ones.
Most people don't need latency, and I don't really have any latency issues. I watch videos with Bluetooth headphones and they're all synchronized perfectly.
With Bluetooth I can also "just... plug it in, bam, music in my ears."
LE Audio should fix the quality and latency problems. The latency is significantly lower and the bandwidth is twice Classic Bluetooth. There are new default codecs that are better, and there should be enough bandwidth for lossless. The other nice thing is enough bandwidth for bidirectional streams instead of low quality audio when use microphone.
The current problem is that LE Audio implementations are new with lots of headphones having them as beta.
Shouldn't it be the same thing? You either have the DAC on your phone convert the digital music file to an analog signal and send it over the aux cord to the speakers in the headphones, or have the digital file sent over Bluetooth and converted by a DAC in the headphones, right? It's not like you're plugging your headphones into a record player.
> have the digital file sent over Bluetooth and converted by a DAC in the headphones, right
This is not how Bluetooth wireless audio works. PCM audio is re-encoded on-device into any one of a few Bluetooth-capable codecs that is then streamed to the client device. This is a primary cause of latency.
The way its bandwidth is too low to broadcast and receive at high quality at the same time meaning everyone calling into the zoom call with their fancy airpods sound like they're calling from the other side of the moon while my 5$ plug-in earbuds sound like a damn recording studio in comparison.
One of my iPhone SE's died an untimely death because of failure of the lightning port, so I'm strongly sympathetic.
I also am a hardcore 3.5mm headphone user. Wireless headphones are garbage.
I did get my mind changed on USB-C DACs by way of inductive charging. Using an USB-C DAC and still being able to inductively charge seems at least somewaht reasonable to me.
On the newest round of phones for my wife and me I've tried to make sure we're inductively charging >90% of the time.
Need to dig deeper into inductive charging as it seems to heat the battery more especially if the phone is in a case. So yet another tradeoff to consider.
Good thing is that if the port goes bad it can still be charged.
I think it just adds friction (for measure, I feel audio jacks are pretty good)
So the real response is, "what's wrong with most companies to not provide the 3.5mm itself?"
It's good that xperia's doing this though. I think I still have phones which have 3.5mm itself so there isn't much to worry about. I think there are a lot of new phones which do offer it, I think both of my parents phones have support for 3.5mm by itself.
USB-C extension cables aren't allowed, but pass-through charging is allowed. I suspect a $7 cable from a Chinese amazon seller is not spec-compliant, but e.g. Belkin sells a spec-compliant "3.5mm Audio + USB-C Charge Adapter".
In my experience the connection is much easier to accidentally break through movement (e.g., walking) with a USB-C adapter than straight-through 3.5mm.
I really miss having a 3.5mm output on my phone...
Hidden inside of a USB-C to 3.5mm adapter is an entire DAC with a power amplifier for driving headphones. They're complex little things.
And like any other bit of active, plug-in electronics: They're not all the same.
Some of them are wonderful (Apple's adapter sounds great and don't cost much), but and some of them are terrible.
And there's compatibility issues. The combination of an Apple headphone adapter on an Android produces a volume control bug that prevents a person from turning it up even to normal line level output voltages that normal audio equipment expects.
And there's functional issues: Want to play some lossless audio in the car or low-latency audio on headphones, and charge your phone at the same time? Good luck with that! (Yeah, there's adapters that have USB C inputs for power, too. They're a mess. And I once popped one as soon as my phone negotiated a 12VDC USB PD mode instead of the 5VDC that the adapter must have been made for. (And no, wireless charging isn't a solution. It's a bandaid for the deliberately-inflicted footgun incident that brought us here to begin with.))
And it's complicated: For a "simple" audio output, we've got USB 2 with a signalling rate of 480Mbps and a power supply, when all we really want is 20Hz-20KHz analog audio with left, right, ground, and (optionally) microphone.
And then: It often doesn't work. When I plug the USB C headphone adapter I have into my car and go for a drive, it disconnects sometimes: I observe no physical change, but the device resets, the music stops, and the phone rudely presents a prompt asking me which voice assistant I'd like to use (the answer is, of course, "None" -- it's always "None", but it asks anyway). And then I get to figure out how to make it play music again, which presents either a safety issue or a time-suck issue while I stop somewhere to futz with it. (Oh, right. Did I mention that the electronics in these adapters also include support for control buttons? I guess I glossed over that.)
Forcing the use of USB C headphone adapters and their complexities represents a very Rube Goldberg-esque solution to the simple problem of audio interconnection that had already been completely solved for as long as any of us reading this here have been alive.
Except: While Rube Goldberg contraptions are usually at least entertaining, this is just inelegant and disdainful.
If you’re in the low percent running cabled headphones, you probably are also running a headphone amp if necessary or not which uses more cell phone power.
Now you need a usb->usb + 3.5mm to keep it charged up or an add on battery.
It seems nobody recalls how bad it was back in the day. CDMA phones (Mostly carriers like Alltel, Verizon and sprint.) did not have sim cards until 4g/LTE. Before that to migrate phones you had to get customer support involved.
AT&T and other GSM based carriers had sim cards on their phones and it was so much nicer.
Nobody has been able to convince me that esim is not just going back in time 15+ years. We moved to sim cards for a reason.
My telco requires that I receive an SMS on my eSIM to move it to new phone so... yeah.
It's amazing if the phone for whatever reason doesn't work and that then requires a long customer support call that might not work. The direct phone-to-phone transfter the devices offer is also blocked on the carrier.
Another issue I had was (travel) eSIMs failing to provision because the carrier didn't whitelist my phone brand/model. The QR code was spent, my money gone and customer support nowhere to be found.
I've never had such issues with pSIMs in decade before. It's ridiculous.
When I lost my phone with a physical sim, I had to go to the operator' office and answer a quiz about which three different numbers I've called and received and when exactly did that happened. Apparently I've failed and they demanded that I would bring a phone box with IMEI sticker on it (yes, the one which all "influencers" tell us we don't need to keep) and then they restored me my sim card. I imagine the same process would be required for the lost esim.
What country was this in? Quizzes and phone boxes sound.. odd. I've never heard of anything more complicated than rolling into your telco's nearest kiosk with your ID and them just provisioning a new one for you.
Lost phone was in Ukraine. We have both prepaid sim-cards and contract sim-cards. Contract would work like you've describes. Prepaid is more complicated.
Totally different experience. Especially when traveling for work, being able to just show up in a country, download an app, and have a working local number within minutes is fantastic.
I have 6 eSIMs on my iPhone, two are active. No stuffing about with swapping physical hardware just because I've temporarily relocated myself.
>being able to just show up in a country, download an app
This seems like a "draw the rest of the owl" situation. If I arrive in a new country with no phone data (which is why I need a sim in the first place) then how do I download an app? Being able to walk up to a guy at the airport and within seconds slide in a SIM solves that data problem.
not all airports have that. and even when they do I have had to fight to stay online or get online requiring entering email and clicking the link in the email before being granted online access.
As the other comment said it's either airport wifi, prep beforehand, roaming data (if absolutely necessary), or (last resort) you go to a physical phone store usually in an airport and they will set it up for you.
I can download T-Mobile eSIM from Australia - Pay them $15, know what my +1 USA number will be, all before leaving the country. You just can't do this with classical sims.
I've found this as well; totally painless to add a destination data plan just before jumping on the plane. And even switching my local plan was pretty straightforward when a promo offer came in from a competitor.
That said, I'm sympathetic to the stance of the article's author. I recently had a scare with my iPhone 13's battery not being able to charge (it recovered itself eventually) and I realized it was going to be a hassle to switch to another phone if I couldn't get the old one powered on enough to run the esim transfer, much less the whole OS migration.
Note that if you just have a broken phone you don't need a new SIM, you just pop it out and pop it in the new phone. So 1min for a physical SIM vs 0-3 hours to create a new eSIM profile. I know which one will be faster. :)
Yes, that was the situation for me exactly, that basically if I lose or break my phone, I obviously have other devices that can access 1Password and my email, but I'm locked out of anything that requires SMS or an authenticator app to 2FA.
Definitely made me feel that at the very least I should be getting a yubikey so that I can have authenticator codes across multiple devices.
Back when eSIM was relatively new, while upgrading to a newer iPhone, my wife’s eSIM didn’t get transferred over but still got deactivated on the old phone.
And the T-Mobile Germany portal to download a new eSIM required authentication via SMS to that now deactivated number. That was fun. (As they didn’t have an alternative procedures to provision eSIMs in place, we had to go visit a store to get a new physical SIM first and could then convert that to eSIM.)
That's interesting that you can "convert" them. I kind of thought the whole point was there was some non-replicable internal secret that the carrier puts in there and that's why it had to be running on their hardware for so long, since they didn't trust your hardware to do that job.
In my country my number is legally mine for I think 60 days after I stop paying for it or something happens like a faulty transfer. I don't have that issue either.
"No stuffing about with swapping physical hardware just because I've temporarily relocated myself."
That's exactly the use case for which the carriers offer roaming plans. The bonus is that you (as in your phone number) get to remain connected and accessible by your contacts, as no other phone number is involved at any point. One should not need to change the SIM unless is about one's phone change.
well yeah, of course esim is shitty, as is everything imposed by big tech monopolies to their users without consulting or caring about what they really want. Did you think they were here for your wellbeing and not the money ?
eSIM is specifically designed to deny user freedom.
They are impossible to transfer from device to device by design, for one. Every single "transfer" has to be approved and signed off by a cellular provider in an online mode. They can deny it at will, or just neglect implementing it, and you can do nothing at all.
It's pretty clear that when GSMA talks of "security", they mean "security of the business models". What does that mean for the users? It means they're getting fucked.
esim.me, 9esim and "sysmocom eUICC for eSIM" are eSIMs in the SIM card form factor that you can load the SIM profiles onto and use them in any device with a SIM card slot (and of course transfer between devices). In my opinion, that's the best of both worlds.
> It's good, but they're expensive as fuck for what they are.
Yep, I remember a time where you could extract the Ki and IMSI from legit SIMs and write that to a bog standard Goldwafer card (which were also used for cable TV hacking) including some SIM emulation software and thereby clone the SIM. That was like 30 years ago and the only thing that changed in SIMs since then is better encryption.
I'll post an example for the parent just in case they are honestly confused about use cases. Here is one that happened to me. I had an eSIM on my iPhone. My iPhone broke (screen became somewhat unusable, and the phone was stuck in a restarting loop). It was an older model phone so I checked the repair cost and thought I'd rather buy a new one.
Bought a new phone. Now, to transfer my eSIM from the old phone to the new phone, I needed the carrier to approve. But I was away from my home country and on roaming. So I tried to call them. They needed me to use a verification PIN they would send via SMS on the old phone, to verify the transfer to the new one. Impossible since the old phone is unusable.
Back in the day, I'd have just taken out the sim from the old phone and moved it to the new one. Easy peasy.
The only other option in this case now was to visit one of their stores thousands of miles away. Eventually just ended up doing that when I returned weeks later but during this time I could not access several services due to lack of access to my number plus 2 factor codes being sent there.
Moving a sim from phone to phone was seamless. Now the carrier needs to approve this swap. Even with two working phones sometimes it's a hassle and there will be delays while carriers decide to approve the move. There is a new feature that allows you to transfer eSIMs easily between phones but carriers seem to be holding onto their power in this regard and not every carrier will let their sims move so easily. This possibly requires regulators to step in and solve the issue - make it up to the user to move eSIMs. I would count on the EU to make this easier at some point.
On the plus side, eSIMs are nice to be able to signup and provision them through an app. Helps with travel and roaming. So there's that too.
“I’m across an ocean from any of my network’s stores and need to activate a different phone on my regular network and number right now, on the side of the road, without WiFi or a computer or a different, working phone already on my account” is to me the most obvious case where eSIM is weak. And having been in that situation before eSIMs, it was really easy - remove SIM, put in backup phone, use. Not so much now.
this carrier approval to move esim problem is more generalized on modern “smartphones”. unless you opt in to cloud providers holding your data there is no easy way afaik to migrate your authenticator apps to another phone. and a host of other authentication/authorization data is tied to the device in an opaque way. don’t get me started on apple’s unpredictable model of sending 2fa to some other “trusted” device which means tou never know what tou need to bring with you.
> unless you opt in to cloud providers holding your data there is no easy way afaik to migrate your authenticator apps to another phone.
You could self-host Bitwarden/Vaultwarden, or something like that.
> don’t get me started on apple’s unpredictable model of sending 2fa to some other “trusted” device which means tou never know what tou need to bring with you.
I think they send 2FA to all supported devices on one's Apple account?
i just ran into a situation activating a new device in which apple were trying to send to a device i had forgotten to “properly” remove from that icloud account.
and also another situation in which the 2fa code would flash on the remote device and disappear in a fraction of a second. i eventually captured it with screen recording but every time i did it the code was not accepted.
my conclusion: apple had silently ruled that i would not be allowed to activate using that particular icloud account. no idea why. i tried a different one and things went through ok.
that’s good to know thanks but creates more special cases to manage if i just want to backup my stuff so i can manually recover when i need to (on lost device say).
If what you say is true, why would Apple ever force a switch to eSIM? I’m now less likely to buy a new iPhone because I don’t want to deal with this eSIM fiasco. It’s to their detriment. If their goal is to sell more phones, they would want to eliminate all friction to switch to a new phone. So what you are saying doesn’t add up.
My experience with eSIM has so far been quite negative. I’ve upgraded phone twice since being forced to use one by my carrier and it’s been a pain both times. The initial setup of scanning a QR code was nice, why is every subsequent SIM change a 10 step dance in an app (or worse a support call) rather than one phone showing the QR and the other scanning it?
Once this phone needs updating, I’ll be swapping carrier to one that has regular SIM cards.
My colleague had a very hard time moving her European esim (Play) from one iphone to another, because by then she moved from the city where she registered it initially. She had to come back in person and even then it only worked after a second visit, because she had to bring basically all her documents to verify her identity to the operator.
Meanwhile I just swapped boring old plastic card in a minute, while staying at home. I will stay away from esim for a while, maybe processes will mature in a few more years. At least until dual-sim phones are available.
For what it's worth, this is entirely a carrier problem and has little to do with the technology.
Various people and the article have outlined some bad experiences but to give a contrasting example: Digital Republic, a local MVNO here in Switzerland, allows you to replace your eSIM by simply logging into their web portal with TOTP-based 2FA and clicking a button. No SMS, no contact with support, no reidentification.
The flaw with the technology is that it is designed so you need the co-operation of your carrier, when previously you did not. Indeed, for the first versions moving a sim profile could not even be initiated independently by a user, but required them to contact support. Now there is the "device change" protocol which can be triggered by an app on the phone, but I think it still requires the co-operation of carrier servers.
> Now there is the "device change" protocol which can be triggered by an app on the phone, but I think it still requires the co-operation of carrier servers.
And it won't work if your phone is broken, while a regular SIM could still easily be removed.
This is especially bad in the US, where the government doesn't like to force companies to implement consumer-friendly laws. It was such a great thing when GSM SIMs were introduced, to avoid the carrier lock that was so common in the early days of cell phones.
I only have experience with two carriers in NL and they’re the exact opposite.
No QR code, only an iOS app which needs to be installed on the phone using the plan. My mum was visiting from abroad once and I had to download the app on her phone — which required me to first log into the App Store with my Dutch account.
I love e-sims for travel and easy switching, but I also switched my primary number back from an e-sim to a physical sim after I realised what a pain it is to use it in another phone (my provider requires a fresh QR code sent by post to my registered address in order to do the switch - huge pain when my phone went in for repairs so I had to switch twice within two weeks, switching to a secondary phone, and then back to normal phone once it was repaired).
Verizon (and their MVNOs) eSIMs are the worst. Registration is tied to IMEI and enforced via the eSIM's EID. You can't use one if those "physical" eSIMs because if you give Verizon a donor IMEI during registration, the EID of the eSIM doesn't match and activation is rejected.
Verizon even does something like that with physical SIMs. My father got a new phone and we moved the SIM card to it. Some things worked, some didn't. Called customer service, they said you can't just move the SIM like that!
I was using Straight Talk prior to the Verizon acquisition and I've been holding-on to my one remaining pre-acquisition SIM like a rent controlled apartment. I've moved that SIM through a number of phones since I got it back in 2013. I absolutely hate that, moving forward, I have to get Verizon's permission to switch phones.
The first time I heard about eSIM, I assumed it was a scheme to make switching phones and providers hard again, but I had no idea the situation was this dire.
I recently bought a device through my carrier (secondary device, secondary carrier; luckily not my primary device) to replace my existing one.
Old device was still physical SIM new device only eSIM. I paid for it in a store, but it had to be shipped because they don’t have it in stock, even though it was in stock on their website (including after I left). It arrived late, the day before I was set to travel. The rep said I could just turn it on and follow the prompts and it would auto activated. It didn’t. Luckily it didn’t deactivate the old SIM. At least it didn’t until I called tech support and got their help. They said hang up, restart both devices, and the new one should work. Of course it didn’t work and both devices were now unusable. Had to go into a store and have them sort it out there.
On the flip side, being able to have a primary I never change and a secondary that I swap out for international travel has proven to be extremely valuable to me. So you take the bad with the good.
Had a nightmare getting a holiday only e-sim in Australia
Couldn’t set up easily because no wifi
then I just simply could not cancel the damn thing… It required being in Australia, and like the article needed a SMS code and the support was only contactable Australian working hours… who wanted the SMS code again.
So once back in Blighty there was no way… had to cancel the credit card to stop payments
So you are at the mercy of the competence of the provider
I tried using a work eSIM as a secondary SIM to my personal physical SIM on my iPhone in 2022 or 2023. I was taken aback by how poor the experience was, both on the iOS level and the eSIM technology level. At that time I reckoned it's probably like 10 years too early and I don't think I will be giving an eSIM (primary or secondary) a shot sooner than in the 2030s.
The problem with SIMs is that they aren't just credentials and config. They are full applications. Imagine if you needed to run a custom program to connect to every wifi network. It is bonkers. It is absurdly complex and insecure.
A "SIM" should just be a keypair. The subscriber use it to access the network.
It’s more complicated because it has to include logic about which network to connect to and how to tunnel back to the original provider (or partner) while roaming.
So it’s more like: which network to connect to, keys, fallback network selection logic and tunnel logic to get authorisation on a non-home network
Do you have any more details on this? I always thought that once the PDP context is established (which is based on the phone providing an APN and optional credentials, not the SIM), the "tunneling" (if any - local breakout is a thing apparently) is handled by the network and is completely transparent and invisible to the phone.
That's a good point. That is what I meant by "and config" in my first sentence.
IIUC if the keypair was a certificate with a few other fields foreign networks could give you some basic communication with your provider and decided if you should be allowed to use this network and if/how to tunnel you back to the home network.
But the main point is that it should just be data that the user can port around to different devices as they see fit and that they can trust not to do malicious things.
It’s not just config though (unless you consider logic to be config). When you’re roaming, the sim applet has to generate a path back to its home network based on request/responses with the networks it can see and their partners (and their partners’ partners etc.)
It’s effectively multi-hop peer discovery and I don’t think you can encode the general case logic for it as just config.
Edit: as a (rather niche) example, FirstNet sims run a different applet to AT&T sims despite nominal running on the same network because they have special logic to use more networks if they are in an emergency area.
One thing I realized about eSIM is your device needs internet access (either WiFi or another SIM) to get the new eSIM working. While that is usually not a problem, I imagine some people run into issues.
Totally agree. I swap phones a lot and it's a nightmare with eSIM. For example I sometimes use an old phone when I go hiking or to a big festival. Better to have that stolen or broken. Some providers even charge money every time you swap.
Also, if I would drop my phone and break it I can simply remove the SIM and stick it in a backup phone. Can't do that with an esim either without the carrier cooperating.
Luckily all my current used phones still have two sim slots. It's something I select for but I'm sure eventually it will become harder.
Sure for a one month travel SIM it's super handy but I don't want it for my main number.
The way telecommunications works needs a complete overhaul. IMHO it needs something similar to a domain name system where you register (and own) your phone number and control which provider your eSIM is pointing to (like DNS). But so many industries are rooted in control it would be nearly impossible to make any meaningful change.
I am not positioned well to speak to it but a coworker who has spent decades in telcom said that another problem is the certificate authority that holds/controls the certificates to provision these sims. Just the consolidation of who is involved in securing the sims.
With physical sims, only your carrier has the encryption keys to be able to provision (and run e.g. a java program on the sim). With esims, that is not as tightly controlled. Coworker recommended I read about the "sim jacker" exploit, but I have not yet. If anyone is curious, I pass it along.
The funny thing is, I used eSIM on a Pixel 3, since it was the easiest way to activate on Sprint. Now, no big carrier will use a Pixel 3's eSIM.
But then on Sprint, they tried to copy the CDMA activation system on LTE whereas everyone else just used SIM cards directly. Sprint was very progressive on eSIM even if they were slow to VoLTE.
My Pixel 3 moved to a physical SIM due to switching to T-Mobile 3 months before the merger, and I've mostly used physical SIMs before the Pixel 10 Pro outside of international travel. I avoid MVNOs as my primary service because of the specter of eSIM-only phones, and that was pre-Pixel 10.
And yes, if my Pixel 10 Pro had a physical SIM card slot I'd use it.
I purchased physical eSIM Multicard. It worked quite easily, so now I can handle esims in a virtual/physical way.
And I know what you might think: Isn't that defeating the purpose? No, it is not. I can recive a digital simcard activation, render it on a physical card and use it in any phone. Thats perfect.
And yes, once the phones without a sim-card slot come ... we'll see.
The only eSIM issues I’ve had have been in the US. Some carriers use single-use eSIM QR-codes. So you need a new one for every swap. In Europe and Canada I’ve always been able to reuse the eSIM QR I got initially. Have I just been lucky or has anyone had problems outside the US?
As a counter-anecdote, I've had far more trouble over the years swapping physical SIMs than eSIMs. You'd think that going between two phones that use the same size card would just work, but in practice that isn't (wasn't?) always the case.
Never saw an issue moving a SIM from one phone to another (living in Asia, Europe and the US). However last week I got a Airalo E-Sim and apparently it's not possible to transfer it to my new phone.
eSIMs are perfect for travel. The only downside is that many phones still allow only one or two active eSIMs. Would be great to have all of them active - be able to receive SMS and calls at least.
eSim is fine, SMS "authentication" is once again the f#?*ing problem.
Its going to take congressional action before we can get rid of this menace. All we're doing is half-ass offloading credit and identity checks to cellphone carriers, which do this, and by having a cell phone, you've probably been through an identity and credit check.
My friend's eSIM experience with Tello was pretty good. Their kid got their first phone with an eSIM, and it was stolen a few months later. They were able to transfer the number to a new phone from the Tello website.
I use eSIM a lot during travels. My last phone doesn't came with eSIM support and I bought an eSIM adapter. It's nice because you switch it to another phone like a normal chip.
On the other hand, international roaming has become so much cheaper now that swapping SIMs when you travel is no longer necessary. The legacy carriers still try to fuck you over, but MVNOs and dedicated travel SIMs offer amazing rates: I can get a year of roaming across 120 countries for around US$15.
It's a year of roaming of bottom-of-the-barrel backhaul, whose speeds and latency could make a 56k modem jealous. It is down to pure luck whether you get a route that works well enough to be usable.
You are always better off buying a local prepaid SIM at your destination airport.
There's also BNESIM who say they don't expire at all. I've only had one for a short time so I haven't tested that but so far it lives up to the promise.
Some random person I met dropped their phone in a river, just after arriving in a foreign country. He bought a new phone, but getting back to his phone number was not easy or possible for him (while in a foreign country). If he had an eSIM it would have quickly solved the problem for him. Instead he had to wait until he got home to pop in a new SIM card.
I learned from this experience that maybe eSIM is a good idea and I switched immediately upon hearing this person's story. Did I miss something?
I should have clarified that he dropped the phone in the river AND he did not attempt to get it back from the river, thus the SIM card is considered lost as well :)
> If he had an eSIM it would have quickly solved the problem for him.
Except many carriers have you jump through hoops to activate an eSIM on a new device. Here in the comments one person has to receive a new QR over snail mail.
> in a foreign country [...] If he had an eSIM it would have quickly solved the problem for him. Instead he had to wait until he got home to pop in a new SIM card.
Are you sure that his carrier allows activating an eSIM while roaming? Mine definitely doesn't, which means that if I break my phone while abroad, I lose access to online banking.
FWIW, I dropped my phone in the Chicago River. Crossing a drawbridge, I pulled out my phone to check the time. It slipped and fell - right into the gap in the middle. I peered through the gap to see if was there, and was able to see the splash it made.
Neither SIM nor eSIM would have helped.
In that case, I waited to get home (I didn't live in Illinois) and got a new SIM by mail.
I'm surprised there's no mention yet of carrier activation fees. Isn't that half the point for carrier's? They can bilk you for another $36 for the privilege of issuing a new eSim for your new phone.
I transferred my number from Mint Mobile to Visible 8 months ago or so. I tried to at least. They initiated the number transfer before accepting payment from me. Their iOS app was bugged and their web app had no way to pay. I engaged support and they escalated to engineering. Still had no phone number or cell access for 3 days, with an upcoming trip planned. Ended up getting them to transfer it to US Mobile which has been fine. Probably works a lot of the time but it’s a shitshow.
My wife and I recently switched from T-Mobile to Noble Mobile and it was painless with an eSim. I didn’t have to try to track down my sim slot key, I didn’t have to go to the cell store or wait for a sim card in the mail, I just followed their onboarding instructions and made the new eSim my default. It took about 5 minutes.
What I don't get is that if he wants a physical sim and microsd card, why does he purchase a phone without those? By doing so you are confirming the phone manufacturers choosing to remove the physical sim cards that they made the right choice.
Personally I chose to purchase phones with physical sim card and microsd slots.
esim is a brilliant idea with terrible brain-dead level implementation.
If I can’t take my esim away from a phone and plug it to another one as easy as physical sim - there is zero point in having this bullshit. Just link my cell plan to IMEI or something.
I guess maybe they're worse for professional phone reviewers, who switch phones all the time, but I'm not one. In my experience, I think about two-thirds of the time I've gotten a new phone and wanted to switch to it, the SIM card size had changed, so I needed to get a new one anyways, which could only be done by mail order, so took a few more days. And about half of the time the same SIM card did physically fit, something else went wrong, like the APN names wrong, carrier didn't want to let it activate, RCS failed to work, all of which are virtually impossible to troubleshoot. IMO, the dream of universal SIM card portability has been dead for at least a decade, if not longer, and started long before eSIMs came out.
The eSIM on my current phone Just Worked as far as activating. I haven't tried switching to a new phone with it yet, so I guess I'll have to see how well it works when that happens.
Clearly there are cases when both are better. eSIMs are nice for being able to switch carriers immediately, get set up in a new country you're visiting smoothly, and recover the number from a physically lost phone. Physical SIMs are nice if you want to try out a different phone model, assuming they support the same SIM size and you can find the little tool. And also if your phone is seriously damaged but not physically lost. So not everyone necessarily loves them, but I don't think it's a case of the big bad big tech companies are enshittifying everything.
Most of the issues you described, such as carrier registration issues, are just as likely with eSim as they were with physical SIM cards. The difference is that you can't swap out the eSim physically, which was a pretty reliable way of getting around misconfiguration. This isn't really an indictment of eSim as a technology, but the reality is that Telco's are incredibly slow and inefficient, and by removing a workaround for their incompetence, it can make the problem worse.
I just abandoned AT&T (finally) and transitioned to US Mobile (on VZW) in about 10 minutes thanks to eSIM. New iPhone's don't even work with a regular sim card any longer.
Seems like most of the complaints in here re: eSIM are around how a specific carrier deals with it and less about the technology itself?
Indeed I have a iPhone 17 Pro with two SIM slots with support for eSIM if I want to use it. If Apple goes eSIM only in our country like they have done in some countries, I'll go back to Samsung.
Latency and throughput from a multi-thousand (literally, in the age of IOT and M2M) user network, massive MIMO and beamforming that LTE doesn't support, etc.
I agree that seems to be the ideal balance. Retain the flexibility of being ablen to easily swap your home SIM, but also retain access to eSIMs as a option when travelling. I still use physical SIMs when travelling as it's still easy to get a physical SIM in many countries. Dubai I got offered a free SIM at immigration(!) and in Singapore there were cheap SIMs for sale post-Security. But I imagine that there will be other countries where eSIM may be a better option.
Those days are long, long gone (15 years ago) for most of the US/UK/EU/Australia and parts f Asia. You require government ID to purchase which gets tied to the IMEI.
I upgraded from an iPhone 11 to a 17 and was dreading having to sign in to my carrier’s web site to get an eSIM QR code. I was surprised to see that the phone migration process took care of that - at the end I had the new phone with an eSIM and my usual number, and the old phone with a deactivated SIM card. Super convenient.
> I was surprised to see that the phone migration process took care of that - at the end I had the new phone with an eSIM and my usual number, and the old phone with a deactivated SIM card.
It's nice to know that you're on a telco that supports "eSIM Quick Transfer", but that's still a feature that telcos need to explicitly support.
Spending money to upgrade from model X-1 to the latest X is the well trodden happy path that big tech will actually make work. Author is describing less common workflows which do not receive the same attention and so become a mixed bag when the financial incentive is not so clear for the manufactures.
