I am not sure how common this is in the US or other countries, but in the Czech Republic (maybe in the whole EU?), the carrier is obliged by law to provide you with a special numerical code which you can then use to transfer your phone number to a new carrier without the old carrier being able to do anything about it or indeed being involved in any way at all. This completely erases the need to have a physical SIM in order to keep your phone number.
I am not sure whether carriers here offer prepaid eSIMs though.
- krzyk 4y agoSame in Poland. The usdye is that not all providers support esim (2 out of 4)
- Ayesh 4y agoThis is commonly called Number Portability. I don't think it's mandated by the EU, but every EU country I looked up supported it. In the Netherlands, for example, you can obtain a new SIM card or port number to another NL carrier. KPN uses the PUK code to verify ownership, which I think is great and has the least amount of hassle if you have written down the PUK code that was printed on the SIM package when you first bought it. The downside is that you cannot change the PUK codes.
