I got an iphone 12 mini mid december. its worked great up until last night. I haven’t been getting any texts through from two factor authentication when I try to log in. Sending texts it just says failed to send. It’s not a number carried over from a previous account or network or anything. Is a new number created for this account in december. I message works and the number on the account in settings matches my number.
Edit - i tried the a different sim in the iphone 12 mini and it works fine. i tried my sim in a different iphone and the same issue happens.
