'I Switched To eSIM in 2025, and I am Full of Regret' (arstechnica.com) 95

Google's Pixel 10 series arrived this year as the company's first eSIM-only lineup in the United States, forcing users who wanted to review or buy the new phones to abandon their physical SIM cards entirely. Ryan Whitwam, a senior technology reporter at Ars Technica, made the switch and now regrets it, he says. "In the three months since Google forced me to give up my physical SIM card, I've only needed to move my eSIM occasionally," Whitwam wrote. "Still, my phone number has ended up stuck in limbo on two occasions."

The core problem is how carriers handle verification. When an eSIM transfer fails and you need support, carriers authenticate via SMS -- a message you cannot receive because your SIM is broken. "What should have been 30 seconds of fiddling with a piece of plastic turned into an hour standing around a retail storefront," Whitwam noted.

Apple started this trend by dropping the SIM slot on iPhone 14 in 2022. The space savings are modest: the international iPhone 17 has a smaller battery than its eSIM-only counterpart by only about 8%. Google's US Pixel 10 models offer no such trade-off -- they lack the SIM slot but "unfortunately don't have more of anything compared to the international versions." He concludes: "A physical SIM is essentially foolproof, and eSIM is not."

  • eSIM was never about customers, it was all about control. We obviously don't gain anything as consumers, we only lose. It's the same as the trend for everything to be remotely controlled and revocable. Be it the phone service you pay for, the movie or song or game you buy, even your car at times...

      eSIM was never about customers, it was all about control. We obviously don't gain anything as consumers, we only lose.

      How so? A physical SIM requires physical delivery or pickup. I can get an eSIM from various countries without ever setting foot in those countries. So it makes it way easier to get service when traveling overseas, because you don't have to find a shop and buy a SIM when you get there and hope that the same deals are still active.

      Also, you can have 8 eSIMs ready to switch at a moment's notice, with two active. Doing that with physical cards is a pain even if you have a dual-SIM phone (which are basically nonexistent in the U.S.).

          Phones with SIM slots still exist which means you do have a meaningful choice. Buy a phone with a slot and vote with your dollars. I'm sure the marketing people at Apple and Google looked at the numbers and fed that into their decision.

            Most of the world has phones with a SIM slot and support for eSIMs. IIRC Apple (and now Google) removed the SIM from their phones because most Americans don't swap SIMs much.

            The guy who wrote the article is a niche user who swaps his (e)SIM between several phones fairly frequently, probably sitting at his desk. That's definitely a use case where a physical SIM is superior. For pretty much everything else an eSIM is better.

                The article author transfers eSIMS between phones frequently, several times a month. Swapping eSIMS in one phone is easy, quick and much superior to the physical kind. Swapping between phones apparently runs into some problems if your carrier is braindead. That's what the article is complaining about.

        • When Apple introduced the eSIM, the phone also had a physical SIM, so you could do dual-SIMs. Now they've gotten rid of the physical SIM slot on US and other iPhones (they still remain on Chinese iPhones I believe). We're also seeing other phone makers do the same. They do still support dual-eSIMs, so you can have your normal carrier and then add another. For example, I have T-Mobile and when I travel, I use the Airalo app, which allows me to install an eSIM and get data in any country. Then I can still rou

        • so the OP is still correct.

          About what? There's zero additional control for eSIMs over normal SIMs. SIMs as they stand allow blacklisting, allow whitelisting, and can be remotely disabled. The carrier has the same control over eSIMs as normal SIMs.

          • I think it is more about KYC. Ordinary sim cards are potentially too anonymous.
            • by ceoyoyo ( 59147 )

              Not many carriers will mail you a SIM card, and even if they did you'd have to somehow acquire a mailbox or address anonymously. Lots of them will e-mail you an eSIM to your shadycharacter1337@gmail.com e-mail though.

            • False. The anonymity of a SIM is the same. The carrier can (and in many places in the world does) blacklist them until they are verified. There's a reason you need to hand over your passport to buy a SIM in some countries, or in others when you get a SIM from a supermarket you need to register it online first.

              The process for activation can be identical for SIM as eSIM, the only difference is the method at which the data gets to your phone (barcode / over the air, vs physical)

I also benefit from the eSIM for similar reasons, but the article is clearly pointing out a serious problem with them and that problem is not really just by accident. Operators long disliked the physical SIM card for a bunch of reasons and the eSIM addresses a bunch of the things mobile operators hate; inventory, techinical support of the SIMs and so on.

        • Let's be real, this isn't an issue impacting 99.9999% of users. This guy is crying about some 1 in 500 million use case. The benefits and security offered by eSIMs far outweigh the issues it presents to a very very small number of users with non-standard use cases.

            Lets be real, not everyone is wealthy. Some of us have cheap plans with little support and old phones. Swapping a sim is way easier then posting to a forum looking for a method to move an eSIM to a different phone and those same people don't travel.
            It's a K shaped economy with 80% of people falling behind and trying to save money so just because for the 20% eSIM's are great doesn't mean that no one benefits from regular sim cards.

    • Sure the sell is that eSIM is convenience for travelers, but the reality is that eSIM provides Apple another opportunity to remove another hardware component to save money and remove another hole from the iPhone chassis. Once wireless charging actually gets popular enough to never needing to plug in a cable, that hole will also be removed. Finally a truly sealed black box to sell to consumers.

      That's why they don't include the charger anymore, they want everyone switched onto wireless charging so they can

        not only remove a hardware component, but more importantly, remove the only moving part on a cell phone. without a sim card slot the phone can come truly hermetically sealed, it really is just a glass slab, nothing to break, no seam or hinge or slide to get grime and dirt in

    • I'm not sure you understand what an eSIM is or how it works. From a technology point of view it provides not one iota of additional control to carriers. They retain all the same ability to provision or block or prevent transfer of numbers they have with physical SIMs. Just because you have a little card doesn't mean it works unless the carrier green lights it. From a lock-in point of view eSIMs are 100% identical to physical ones.

      From a consumer point of view they are much more flexible. The ability to wire

      • The ability to wirelessly provision a SIM is a godsend for anyone who dares set foot out of their country. I know a lot of Americans simply don't travel, but the reality is the ability to provision in advance, or virtually without having to go buy something physical or go to a store is a fucking GODSEND, especially at tourist hotspots where you're bound to have someone try and defraud you in the process.

        For the last 20 years in dozens of countries, I have had no trouble at all just buying a local SIM in whichever country I land in. Usually costs about 5 bucks, except in the USA and UK where it's 10 times that, or even worse if buying at the airport. If travelling in the EU one can stick with the same SIM right across the continent. Elsewhere it might be cheaper to get a new SIM in each country. I've been ripped off exactly ONCE, in France of all places. The SIM worked fine but the topups didn't, at least n

    • How exactly does a carrier do that? When a carrier "gives you an eSIM", what it's doing is creating an eSIM profile that you can switch to. If you have another carrier, they too can create a profile. If you have a problem w/ any carrier, you can call them to cancel, and also delete their eSIM profile in Settings
      • If you have another carrier, they too can create a profile.

        That requires an unlocked phone. If the phone is locked it will reject the eSIM from an operator that the locking operator doesn't want to allow.

        Ask somebody who's not technical if they know how to do this process.
        • For non-technical people, worst case scenario is eSIM changes nothing except for being faster. They walk into a store front, ask how they can try out the new offer, the clerk does something for them, and it works right away. A better case is the clerk shows them how easy it is to switch from an operator to another. It's like switching from a wifi to another, or to mobile data. Even non-technical people can be made to understand where to look for eSIM profiles and switch between them.

      Good question. Back in the old 3G GSM days, one only needed to specify a "four band" model. Buy one in the EU (unlocked) and bring it back to the USA and it would work fine. That's how I rolled for years.

      Now, when I walk into a phone store and ask about "international capable" 5G phones, the sales people wet their pants. It's not a question that cannot be answered (the options being "yes" or "no") but one that management has instructed them to skirt around.

  • When I heard that there are phones now that only support eSIM I knew that I would have to be very careful not to buy one. I travel extensively, I have to switch sim cards, I sometimes have to use multiple phones, sometimes the phone has to be replaced because it got destroyed (water damage) and if I am somewhere in Asia I am still working (in multiple time zones). It's crazy to think that I would go for an electronic SIM card that cannot be moved physically from one phone to another.

    • That is what eSIM profiles are for. If you are going from one country to another, you can have one profile for, say Verizon and another for SINGTEL in Singapore. Similarly, if you're switching b/w AT&T and T-Mobile often, you can have one profile for each and switch b/w them. The thing about eSIMs is that one can have several profiles, but only one is active at any given time, but one doesn't have to physically swap SIMs

      If you have different phones, one thing that might be an issue is moving a numb

      • ha!!!! Right. So I can get stuck somewhere without a working phone and internet and to move the profile I have to access the carrier. Access them. During a trip. Without a working phone. On a weekend or some stupid ass holiday (of which there are tons every month).

        Yeah, that is what I need exactly. No, I will not buy an eSIM only headache.

        • What you buy is obviously up to you. However, you don't have to access the carrier in order to switch to the profile (assuming that the carrier in question is operational wherever you happen to be at that moment). You go into settings, then into the section where you adjust the carrier settings. There, you can enable the profile in question, and then use that

          • It is quite simple. Instead of buying or borrowing a working phone and swapping the sim card, you just need to take an entire Apple phone store with you wherever you go, then you just walk in (during working hours, of course) and have them move the eSim over to the replacement device. You are just making a mountain out of a molehill.

              • Oops! I am a silly sausage. Sorry.

                FWIW I oppose eSIMs because they need the co-operation of the vendor to swap around. If, for instance, I have no or intermittent data and want to troubleshoot the problem, I can quickly swap a SIM between handsets and find out which is the culprit.

    I ran into a problem with the eSIM on iOS when it first rolled out. Something got corrupted or whatever, I can't recall -- but, there was no recourse other than going to a real Verizon store (not a reseller) and having them fix it. The clerk there at the Verizon store used strong language about eSIM, indicating it was causing them a lot of grief (that I was not alone). Perhaps they will eventually fix it.

    But, what about a spare eSIM? I can have a spare physical SIM. Would this have been mitigated if I had a spare?

    I'm surprised by now they haven't done something with blockchain and eSIM -- LOL -- that's probably next.

    In any case, I feel like it was hastily rolled out and we can see the fallout from that. I wonder if there are better ways to accomplish this -- but I am fine with a physical SIM.

    • I ran into a problem with the eSIM on iOS when it first rolled out. Something got corrupted or whatever, I can't recall

      Isn't this the crux of the issue? eSIM is convenient, but when it fails, then the fix is harder.

      • by ceoyoyo ( 59147 )

        Is it? An eSIM is just the contents of a regular SIM running in a virtual machine. If your physical SIM dies you have to go get another. If you eSIM dies somehow you have to get someone to give you another. The difference is that they can e-mail you the new eSIM.

    • But, what about a spare eSIM? I can have a spare physical SIM. Would this have been mitigated if I had a spare?

      What do you mean spare eSIM. You can provision multiple eSIMs just like physical SIMs. My phone supports 2 active eSIMs (dual SIM) with 20 inactive stored eSIMs which I can select at a whim.

    I just checked from two different operators how you autenticate eSIM. They don't send you an SMS, instead you login to their webpage using e.g. your bank account to identify yourself. Then you scan QR code and that is about it. (You will need a WIFI connection.)

    So AFAIK there is nothing in the eSIM that mandates the usage of SMS. That is probably just operator specific way to operate.

    • Some wires got crossed for sure, the most common scenario (or at least a common enough one) for replacing (e)SIMs is just losing the phone, SIM or eSIM in it. Of course it can't be that the authentication for that goes over SMS, obviously.

    • Most of the fuckery is in the UI and carrier support side of things. I wouldn't bet against there being some ugly edge cases hiding out here and there; but the GMSA and its members take boring fiddly details of remote eSIM provisioning pretty seriously, both because they hate theft of service/SIM cloning/etc. and because incompatibilities are a real problem if the smartcard IC is soldered to the logic board rather than in a UICC that the carrier can choose a vendor for if there's some quirk to work around.

    In the three months since Google forced me to give up my physical SIM card, I've only needed to move my eSIM occasionally

    "Only occasionally" over a three-month period. I think his definition of "occasionally" is a little different from mine.

    • Indeed. The "normal" user would expect to transfer an eSIM from one phone to another maybe every 3-5 years, sometimes less. I've done it once, the process was flawless, painless, and didn't require any SMS.

      I suspect TFA is AI generated ragebait.

  • This is bad news if the Pixels are now eSIM only.

    GrapheneOS only supports pixels and many of its users prefer a permissionless SIM.

    Maybe they'll add support for some other device, perhaps one of the privacy phones.

  • SIMs are retarded and this whole thing is a legacy system built on paradigms from an ancient world. Digital connectivity should be free and require no personal brokering with infrastructure maintainers. You'd simply purchase a device and it would have wireless Internet connectivity. It would be paid for by taking away a small fraction of the annual spending on "foreign aid" and diverting it to this essential public service...though obviously there's no mechanism in place to prevent any type of government pr

  • So far, I haven't had an eSIM fail on me - Since around 2000 I've had at least a couple traditional SIMs fail though. While that's anecdotal, so is the original topic here. TBF, I don't swap SIMs often - I suspect if I did, I'd have had even more traditional SIMs fail, and possibly some eSIMs too. Carrier technology is garbage all around.

  • I found a lost phone once. Being a good Samaritan with some ofsec skills, I pulled the SIM out and ran some fundamental OSINT software. Within 10 minutes I had access to the person's full name, email, home address, 50 different online account handles, his number plates and family member names.

    Imagine his surprise, relief but also sheer horror when a complete stranger knocked on his door to return the handset.

    Since, like most people, his SIM pin was 0000, I would probably have no problem breaking into some/m

  • So if my phone dies, say it fell and screen broke or it just stopped booting up, how can I move the e-sim to my spare phone ?

    Normally I would just take out the Sim & put in the other phone. 10 seconds.

    With e-sim obviously I can't do that, nor can I do anything like "export" e-sim from broken phone since it's not booting up /usable

    I guess I have to borrow a phone and call up the operator who will somehow authenticate me, probably just by emailing e-sim info/code to my registered email ID. Then I enter t

  • eSIM works flawlessly in Brazil. I have never had a problem with it. It also makes it much easier to obtain local numbers in other countries upon arrival. By contrast, the situations described in the article suggest that the U.S. infrastructure is comparatively low quality. Additionally, eSIM is significantly more secure and simplifies blocking a device if it is stolen. The complaints outlined in the article do not resonate with my experience at all.

Progress means replacing a theory that is wrong with one more subtly wrong.
