I have never used esim, but I’m considering trying it out on my Samsung galaxy s23.
The thing is - I will probably unlock my device when the warranty period is over. So If I unlock the device while esim is enabled, what will happen to the esim(s) ?
Will I have to register for a new esim or use my physical SIM card again to get back my esim ?
You still get to use it as normal, so long as you have service. That said, I personal stick to physical SIM just to minimize any problems, but you do you.
So even flashing a new ROM on the device won’t erase the eSIM right ?
Even if it does, you just set it back up again the same way you did the first time.
