I don't understand how this wasn't more of a priority to begin with. If you're going to offer a digital solution for something it should at least be as convenient as the existing physical solution.

[–] Melonpoly@lemmy.world 6 points 9 months ago (1 children)

This is just an assumption, but I thought the whole point was to make it more difficult for people to switch carriers?

[–] deweydecibel@lemmy.world 4 points 9 months ago* (last edited 9 months ago)

Also because it's locking another aspect of the device behind software that you do not have control over, which gives carriers and phone manufacturers some new levers to exact control over how and what you do.

Because evidently we haven't learned our lesson yet.

Like when the SD card slots got taken away, and now not only are most phones storage non-expandable, you can't even use a proper file explorer on Android anymore.

Uh, I assumed that was a minimum viable product requirement.

I've been avoiding eSIMs like a Boomer avoids anything tech because I don't understand them, and now I'm glad I did.

SIM cards work fine; other than waste reduction, what's the point of eSIM?

[–] axby@lemmy.ca 5 points 9 months ago* (last edited 9 months ago)

I still prefer a physical SIM for my main cell plan, but when travelling to other countries it is so amazing to be able to just download an eSIM and avoid roaming fees. Airalo is quite convenient, but I hear it’s getting pricey compared to other options.

Plus with dual SIM I can disable roaming on my main SIM but still receive texts for free, but use data for cheap with the local eSIM at the same time.

Disclaimer: I live in Canada which has some of the most expensive cell plans in the world. Roaming in the US is $13 CAD/day and $16 CAD/day in the rest of the world. That seems like blatant extortion to me, they can’t blame Canada’s large size for expensive roaming fees (right?). I think US plans are a lot better, and I assume European cell plans are generally even cheaper.

Edit: I prefer physical SIMs for my main plan because if my main phone is dead or broken, I can just pop the physical SIM in an old phone that I bring while travelling. Until eSIMs can be somehow transferred like that, I don’t see myself using them for my main cell plan. Just remember to set a SIM PIN so that if someone steals your phone, they can’t use your SIM card to receive 2FA texts.

Edit 2: eSIMs are generally a pain to transfer between phones. I think my cell provider lets you do it online by scanning a QR code, but I know some make you call them and read 16 digit codes over the phone. Some even charge a small fee. I dread the day where other cell phone manufacturers follow what Apple did in the US (I think?) and make eSIMs the only option.

[–] twix@infosec.pub 4 points 9 months ago (2 children)

Well, on the other hand, do you just understand how simple cards work? I for sure don’t and I don’t see why I would need a chip from my provider to access it’s services, if I can get a digital key instead.

[–] Auli@lemmy.ca 9 points 9 months ago (4 children)

I like that I can switch phones with a physical card. IPhone to android still no way.

As I understand it (I've done literally zero research), it's to prevent spam/spoofing, at least in the US. With a physical card, you can't just instantly convert your phone to a different number and carrier. Now, with all the robocalls I get, there's obviously still more work to be done...

[–] Auli@lemmy.ca 3 points 9 months ago* (last edited 9 months ago) (1 children)

Spoofing what? Imei numbers? Phone number spoofing is not solved by this. With VOIP you can literally tell it to send whatever number you want to be its caller I'd.

[–] ColeSloth@discuss.tchncs.de 5 points 9 months ago

Not that simple type of spoofing. The kind where I could set up a phone with your number on your network that the network thinks is yours and then intercept your incoming calls and text messages. Including being able to get your security texts to verify who you are when I would change your passwords, emails, banking info, stock accounts, etc.

[–] RogueBanana@lemmy.zip 3 points 9 months ago

I could see security being one but the only reason that I got one is lack of dual sim tray on my pixel

Okay, now do it when the phone is broken.

[–] kratoz29@lemm.ee 3 points 9 months ago

The hard way I see.

[–] umbrella@lemmy.ml 47 points 9 months ago* (last edited 9 months ago) (4 children)

physical sims can be swapped regardless of OS or whatever arbitrary limitation they impose on us.

i still dont get why esims are a thing besides imposing more control over us

[–] Technoguyfication@sh.itjust.works 30 points 9 months ago (2 children)

When I traveled across the world last year it took me 5 minutes to sign up for a temporary cell plan in the country I was visiting, then install the eSIM from my phone’s web browser. I didn’t have to plan ahead and wait for them to mail me a SIM card so I could juggle around SIMs while abroad. I much prefer that over a physical SIM card.

[–] umbrella@lemmy.ml 10 points 9 months ago (2 children)

im glad you had a good experience in the random country you were in.

but have you ever dealt with most carriers? also who waits for sim cards in the mail instead of just buying one?

[–] Technoguyfication@sh.itjust.works 10 points 9 months ago

For reference, this was in Japan. From my experience, there weren’t SIM card vendors until you get through customs. That could be a 2 hour long process from landing to entering the country before you can get a SIM and communicate with family or your travel arrangements at your destination. It also won’t be doing you any favors if you need to pull up documentation on your phone to provide to the customs agent, like your return ticket.

I can buy an eSIM and install it before leaving my home and verify it works instantly. It’s just a better experience than the alternative.

[–] ArtificialLink@lemy.lol 2 points 9 months ago

also who waits for sim cards in the mail instead of just buying one?

Cellphone carriers that have no brick and mortar? But are also significantly cheaper for basically the same service

[–] Kusimulkku@lemm.ee 2 points 9 months ago* (last edited 9 months ago)

I just bought up a few prepaids and popped them into my phone when I wanted to use them. Also we shared them between people. Not sure how sharing works on eSIMs

[–] Overzeetop@beehaw.org 4 points 9 months ago

Maybe in somewhere free like the EU or SEA. In the US, most phones bought from a carrier (and most sales are that way, some exclusively so) are locked so that no other SIM (e or physical) can be used.

How do these eSIMs work from a user's perspective? I've only ever had phones with physical sim slots

[–] 9point6@lemmy.world 19 points 9 months ago (1 children)

Effectively, imagine there's a SIM card soldered to the motherboard of the phone, you can then download an eSIM to it and the phone behaves as if it's a physical SIM.

In reality it's generally built into the modem and I believe they can typically hold multiple eSIMs. What I'm not clear on is if inactive eSIMs actually live in the hardware eSIM or if they get swapped in by the OS

Yeah same, I want to know how you move phones if one breaks, or any number of similar situations where you can't run an app or access another device

[–] AdmiralShat@programming.dev 5 points 9 months ago (2 children)

That's my big concern as well.

Its a shitty replacement. If I couldnswap phones like a sim card i wouldn't care. But they charge for a phone swap no thanks.

[–] SheeEttin@programming.dev 2 points 9 months ago (4 children)

You call support and have them issue a new one.

[–] Pika@sh.itjust.works 2 points 9 months ago

yea, that's my biggest annoyance with it, if you can't pass security on the phone (talking to you prepaid carriers who have absolutely shit CS and protocols) you can no longer just hot swap the sim to get your verification code. You are just locked out of your account now. It's nice that it's more secure but, also such a pain in the ass for people who don't call their carrier a lot so they don't know their security.

[–] Kusimulkku@lemm.ee 2 points 9 months ago (1 children)

Don't you need a SIM for calling?

Exactly the same as a normal one. It just works and you don't really need to do anything with it. Everything seems the same just no little card in the side of your device.

[–] MicrowavedTea@infosec.pub 10 points 9 months ago (2 children)

Until this article I thought you could swap eSIMs between phones, exactly like normal ones

[–] 9point6@lemmy.world 4 points 9 months ago (4 children)

Tbh I think you effectively could, but it would technically be your provider issuing a new one.

For me I just log into my provider's online account screen and I'm able to scan a new QR code

[–] MicrowavedTea@infosec.pub 4 points 9 months ago (1 children)

Eh that's not really the same. And reading this thread it seems many providers (including mine) don't support online QR codes.

[–] 9point6@lemmy.world 3 points 9 months ago

That's unfortunate, at least in the UK all the (eSIM supporting) providers seem to offer the same capability.

As I've said elsewhere a physical SIM is slightly better in the situation where you smash your phone and buy a new one as you don't need to connect your new phone to the phone shop's WiFi for 5 mins (scanning the QR code is the quick way, you can just type an alphanumeric code in too, some carriers let you download it via an app). On the flip side though, if your phone is stolen, I still just need the WiFi for 5 mins. With a physical SIM, it would be sent to my home address and arrive a couple of days later.

@AdmiralShat @FragmentedChicken phones that support esims have actual sim chips inside, and esims basically flash the carrier data onto that chip.

[–] mp3@lemmy.ca 3 points 9 months ago

They're functionally the same as normal SIM, instead it is stored in a secure location of the storage (which can survive factory reset). In a way, it makes it a bit more secure as a thief can't just yank out the SIM card to avoid being tracked (although it doesn't defeat a faraday bag) or take it out to use it in another phone.

[–] pimento64@sopuli.xyz 2 points 9 months ago (1 children)

The same way Verizon phones used to work: less well.

Generally you go to some site your carrier has, enter the IMEI or some number from your phone's settings, then scan a QR code. It's not bad... depending on your carrier.

[–] Auli@lemmy.ca 3 points 9 months ago

And pay a fee.

This thread made me wonder how often y'all change phones. It sounds like four times a day.

[–] henfredemars@infosec.pub 2 points 9 months ago* (last edited 9 months ago)

For me it's about every 1 to 2 years, but I'm an app developer part-time so I use it to make money which justifies the high cost of ownership. I keep the trail of older phones for testing on different models.

For my wife, it's more like 4 years, and we prefer to get last year's model especially with today's update commitments.

[–] evo@sh.itjust.works 4 points 9 months ago

Nice. That is always the most tedious and annoying part of switching phones every single time for me.

but some carriers don't
