If your old phone was also eSIM compatible, you can just download the eSIM from your carrier like you would if you moved to any other phone.

But you would need to somehow get in touch with said carrier. Granted, you could probably do that over WiFi but if my phone breaks when, say, I'm out camping I'm SoL.

  While I could see how the camping scenario might matter to a few people, I would personally rather have a couple mAh larger battery because of the slight physical space savings that I imagine eSIM brings.

    Oh yeah, agreed. If moving an eSIM requires me stowing away a QR code with my backup phone then I'll gladly give up my physical SIM slot for more battery.

  The associated esim app has free connectivity to complete the signup flow without wifi. It is obviously more convenient to download an app to your backup phone than futz around with physical sims you just have to remember to do so before you go camping. Now you might retort aha! See! In a very narrow set of circumstances.. let me cut you off, look, you're going to need to remember to bring a paperclip or sim tool to do it the old fashioned way anyhow. So you're remembering something. If you're an amnesic lost in the woods you got bigger problems. Besides, those are 2 grams of weight savings in my ultra light backpacking setup!

  Would you bring a spare phone then? Sounds implausible. If you did, and it’s an emergency you can use a phone without a sim at all with the emergency network.

    I actually do, it's always good to have a few back up essential things if they don't take up too much space. Every time I go camping/travelling I update my old OnePlus 3T (LineageOS is still up-to-date which is amazing) and bring it with me. If my iPhone breaks I can move the SIM card and still keep at it.

      Agreed. Both wife and I need our phones for work connectivity, and it's a lot easier just to carry our old models in case one of ours dies on a trip. I'm not going to buy an iPhone while on a trip out of the country - they won't even have the models that support Verizon in most markets. My old phone is still logged in to Apple, still works, still holds a charge. I'd like some eSIM system that was as convenient as "phone dies, pull SIM, put in old phone, boot".

  In the UK most carriers also offer printed QR codes for the eSIM. These can be scanned more than once to activate it. So you can store that somewhere and scan it on another phone.

    What happens if you scan it twice on two phones at the same time?
    - martinald 3y ago
      The last one to activate will get service. I think o2 allows 3 scans of the QR code.

Btw, how would one authenticate to the carrier? Concerned anything not perfect would make sim swapping a even bigger problem…

> you can just download the eSIM If we disregard the fact that many older but still usable phones don’t support e-sim (which was the original point), what do you mean ”just” download the e-sim? At least in my country, getting an e-sim is a pretty involved process which requires secure authentication, and specifically in my case that authentication would be gone with the now-broken phone if one didn’t have the foresight to have a backup (which many people do not). If you have a physical sim, you can move it to almost any (unlocked) mobile phone in existence (at least in Europe) and at most you’ll need the PIN/PUK. Of course, this goes the other way as well if you drop your phone in the ocean for example, provided you have alternate authentication and a compatible phone, e-sim will have you up and running again much faster.

  I have Orange Flex. I can just install the app on a new phone, login with email, and have new eSIM issued and installed within a minute.

    Sounds like it would be trivial to compromise your phone number and sms 2fa
    - SSLy 3y ago
      How so? The carrier can issue new SIMs anyway, nothing I can help about, it's a trust or get fucked system. Password to Flex itself is in my 1password db. If that gets compromised I'd have way bigger problems than cloned phone number.

    Not everyone has that option. For my carrier I have to call them and ask if they can help me set up esim each time because I can't do it myself. And each time it takes at least 30 minutes. Plus I just don't trust esim yet, it hasn't been able to shine as a technology. Give it a few years, I'm all for esim, but we have to make the switch gradually. Give me both for now and keep physical sims alive for the next 7+ years to get everyone onboard. By then the process for getting an esim will have gotten waaay smoother.

My carrier don't let you download an eSIM - they have to mail you a physical QR code that has a SIM number then swap them over the phone or in a store. Makes it a week long process at least.
