Alright, so as of almost two weeks ago my device has not allowed me to send or receive calls. It shows I have my full normal signal wherever I go and still allows me to send text messages or use the web or any app. Simply does not send or receive calls. When I hit the call button it immediately stops, makes the hang up beep, says out of service area( while showing full signal), and then a message of call has been lost pops up. Does anyone have a solution for this?
