I set up a go phone today (samsung a157) with an unlimited messaging plan but my text messages do not send. They get timed out and I get asked to try again, and then the same thing happens.
I tried to register my go phone on at&t's support site but I never received my verification pin, so I'm assuming I can't receive messages either. My calls are going through fine and I think I have a sufficient number of service bars right now.
Anything I can try to fix this? Thanks for your help!
