Can't Receive Any Text Messages on My AT&T SIM

Thanks for responding, Marilyn. I called the phone number you suggested this morning, before I got your message, and after having spent about an hour with an AT&T online chat representative yesterday.

This morning I wound up finding the solution to my problem myself while today's rep had me on hold, but I found what needed fixing on a settings screen she'd told me to pull up, so it was a collaborative effort. I will share what fixed my issue here in case it might help anyone else.

After clicking on Settings/About Phone/SIM Card Status on my Samsung Galaxy S20, I noted that "IMS Registration Status" said "Not Registered." I googled how to fix IMS Registration Not Registered, and one of the suggestions I found was to select a local carrier manually rather than having the device choose one automatically. Once I chose a local carrier manually, I started receiving text messages again. I have no idea why that worked, but it did. I've been compulsively sending myself text messages all day to make sure I'm still receiving them, and so far, so good.

I do want to offer some constructive criticism about the apparent lack of internal AT&T communication between the phone reps and the chat reps. The phone rep today did not have access to what the chat rep had already attempted yesterday by way of troubleshooting, and that makes no sense. AT&T should make it possible for a second customer service person -- whether on chat or on phone -- to find out what the first customer service person already tried that did not work. It was very frustrating for me this morning when I had to re-explain to the AT&T phone rep what I had already explained in detail to the AT&T chat rep yesterday. So much wasted time!

Also, yesterday's chat rep advised me that "I will escalate this issue to our backend team to resolve this by the end of the day," but today's phone rep seemed unable to find any evidence that the promised escalation to the backend team had taken place. I just don't understand how that could have happened. 

Still can't receive text messages. I contacted AT&T directly yesterday and was told the issue would be escalated and fixed by the end of the day. The issue was not fixed by the end of the day (or at all), so I am still stranded overseas with no way to receive OTP codes. It AT&T could not fix the problem as promised, it should have at least contacted me with a status update on the effort to resolve it!
