Text messages without pictures follow the same route as voice calls, so that should be working. Text messages with pictures (or group text messages not sent as individual texts, or texts longer than 140 characters) use MMS. Go to AT&T and ask them to check whether your APN is set up correctly for MMS. (You may have to go to a Device Support Center - if it's not the store you go to, they'll tell you where it is.)

Every once in a while the regular texts and the mms will work. Usually for one hour each day. I just don't want to have to get a new phone. The text message service center number is correct as well as the apn.
