I was getting "network authentication failed" when trying to send pictures last night, which was still a problem this morning. I then called *228 and pressed 1, and my problem was solved. A few hours later however, I now have the same problem, and cannot be solved by any combination of *228 ex. 1 or 2 ; powering my phone off ; or taking the battery out. Please help!
If at all possible, I would NOT like to restore my phone.
