I've had Verizon since 2001 and in that time only a hand full of dropped calls, mostly in far out rural areas of TN.

I live in Knoxville and its very rare to experience a dropped calls here. AT&T, on the other hand, stinks. I live in the middle of toown and my friends on AT&T get 1 bar at my house where I get 5. It seems that in moutainous area GSM service absolutely stinks. You can have 4 bars in one spot, walk down the street and suddenly have none. It's like that all over East TN.

I can count on one hand how many of my friends / contacts have AT&T. Everyone else that lives in this area goes with Sprint or Verizon. In some cases Sprint does better than Verizon in the Smokies.
