Ok, so around three today, my phone stopped sending and receiving texts, and calls. I've tried everything. When I hit the "Activate" app, it comes up with error code 06-07-7920. I called the service number, they had me turn my phone off and take the battery out for fifteen seconds, and refreshed my account. That was five hours ago - no help. My phone does still get Internet, though whenever I try to text or call, the 3G symbol goes away. Can anyone help me?
