Being able to make or receive calls on your device is a must, and I'm sorry to hear about the troubles you are experiencing in this one particular area. Let's work together and make sure the connection is all that it should be. To begin, may I have your nearest intersection and city so I can check on the impacted area? Aside from calls, how are your texts and data working for you? Are other people in your area experiencing issues as well?
i'm surprised that a note3 can even use the current network.
my old s5 isn't even usable with most apps because not upgraded to 5.0.
