It's a physical storage about the carrier. as far as i understand it's more convenient for carriers to onboard clients and also for users in general if a phone dies for example you can swap it into another.
There are CDMA enabled phones that do not need a SIM card but they're a pain to transfer to another carrier. At least today.
- vasco 4y agoI don't need to swap a physical thing to log into my bank on another phone if my main one dies. I'm not sure why this is the answer.
- bilekas 4y agoBut imagine you have 2FA sms verification (horrible practice but prevalent) and your phone is dead. Sim swap out is helpful. I don't approve of it personally, but it's a legacy method anyway.
- AnthonyMouse 4y agoThat applies to a physical SIM card, but why is it needed for some eSIM/iSIM that can't be physically separated from the device? At that point it should be done entirely in software.
