When people recieve my text messages, there is a strange 11 digit or so long number that is part of the text messages they receive from me. It isn't anything recognizable so they don't respond to them. A) What is it? B) How do I get that resolved?
My wife and I had this problem for 2 different Thunderbolts. We pulled the battery.. Waited 30 seconds.. Put the battery back in and restarted and it hasn't been an issue since.
