How do these eSIMs work from a user's perspective? I've only ever had phones with physical sim slots
@AdmiralShat @FragmentedChicken phones that support esims have actual sim chips inside, and esims basically flash the carrier data onto that chip.
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

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.
The major function of a normal SIM is the ability to take it out of one device and put it into another one, effectively disconnecting my identity towards the network provider, from the handset. With eSIM, that doesn't exist, and if my phone breaks, it's unclear what happens.
To me, that's not secure, that's unsafe and insecure.

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

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

What if I need to change the SIM?
You get a QR code for the new sim, go into the eSIM manager on the phone, and scan it
I don't want a "new sim", I want my old one, which doesn't exist anymore since it was virtual and only existed in my now broken previous phone. How does it work in that situation?
Call your carrier or go into a store and they move it over. If your phone is broken youβll kinda be SOL since thereβs no way to authenticate the move.

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.
Hah. To swap eSIM on O2 in the UK, you have to order a physical pack that gets posted to you with the QR code in. There is no way to get the code to appear on a screen you can scan with your camera, or in an app on the phone you can transfer to the phone's eSIM manager. It's so dumb.

but some carriers don't
Nice. That is always the most tedious and annoying part of switching phones every single time for me.
