Just curious.
I used eSim for a while when I first got a phone that supported eSim, because I wanted to make it harder for a thief to disable the phone tracking, but now my main phone is broken and I’m a bit annoyed at having to chat with customer support for half and hour to activate eSim on another device.
I use a physical SIM because my phone doesn’t support an eSIM, also i’m preety sure you have to activate it everytime you clean flash a custom ROM.
