3 days ago I lost service on my Razr Maxx, randomly. I couldn't make calls for about 4 hours The signal came and went but no calls to come through or go out. It's been 3 days now and my signal is still horrible, if I manage to get a call to go through it drops and I lose signal completely for 3-5 minutes. I have done a factory reset, and held down the power button and the up volume button. Any hints?
