Yesterday I encountered a problem with my phone: I have full service and I can make phone calls, download, and use internet without a problem. I can also receive messages, but anytime I try to send it seems as if it doesn't even make an effort trying to send. It instantly says 'message not sent'. I have factory reset my phone 3 times since then.
I can't figure out what could cause this....its really frustrating...please help.
