    As I understand it (I’ve done literally zero research), it’s to prevent spam/spoofing, at least in the US. With a physical card, you can’t just instantly convert your phone to a different number and carrier. Now, with all the robocalls I get, there’s obviously still more work to be done…

      Spoofing what? Imei numbers? Phone number spoofing is not solved by this. With VOIP you can literally tell it to send whatever number you want to be its caller I’d.

        Not that simple type of spoofing. The kind where I could set up a phone with your number on your network that the network thinks is yours and then intercept your incoming calls and text messages. Including being able to get your security texts to verify who you are when I would change your passwords, emails, banking info, stock accounts, etc.
