I've always wondered what happens to that number you still use for messengers but don't own anymore:
Why tech companies should stop using phone numbers as user IDs - a super weird story in a thread ⬇️

Yes! Phone numbers as primary identity providers is simply a terrible idea. Especially prepaid. However, the industry just keeps trying to "fix" it. (anti sim swap attack measures etc)
I don't think you mentioned it in the thread, but the other side of this problem is that the new owner, in this case YOU, with that new SIM card in your possession, potentially also now own the accounts associated with it. (depending on 2FA or maybe other policy associated with the accounts.)
@keith Yes, it’s a security nightmare of course. There’s so many reasons this phone number as ID thing is a bad idea :/
