Over the last few days, I have not been able to make any outgoing calls on my Droid Razr and I've received very few incoming calls. My girlfriend can be standing right beside me and call my phone and it won't ring. The call will ring on her end, but nothing on mine. And all the outgoing calls time out and I get a Call Not Connected window. I'm showing a 4G signal with 3 grey bars.
I'm on call 24/hrs a day for my security job and I need to be able to receive calls if there are problems at work or one of my staff needs me. This needs to be resolved please.
