Can't connect current phone number to new iPhone 13
Opened and activated my new iPhone earlier this week, and had some initial issues trying to restore data (didn't notice encryption was turned on for the backup) so did a manual setup. Everything I have loaded so far seems to work EXCEPT:
Can't use the phone to make calls - every call fails
Can't activate iMessages - says the phone number won't authenticate
Can't receive SMS messages to complate two-factor authentications for many of my apps
I have tried the solution to toggle off iMessages, power down / up, and reactivate iMessages. No fix. At this point not sure if the issue is AT&T or Apple, but I can't get into my AT&T account now because, guess what - it wants me to enter a SMS-sent code to verify my identity.
HELP!!!
