We used to have Verizon cell service. Loved it - good service just about everywhere. An occasional dropped call when switching towers. Lousy reception in areas where they acknowledged their service wasn't very good (WV mtns, for example). Had Verizon for many years.........and then we moved 4 years ago.........to what was apparently "The Bermuda Triangle of Verizon Coverage" in central OH. Go a bit up the street either way - good signal. Unless we stood in just the right places with our tin foil hats on, reception on our property was weak at best. Constant dropped calls......not good for my business. Same problems experienced by our neighbors. Verizon sent a tech out to check out the signal issue - they acknowledged there was a problem with the coverage and graciously - and voluntarily - let us out of our current contract with their apologies.
The only service that's usable here at the house? AT&T. So that's what we have now and their service seems every bit as good as what we had with Verizon. Same occasional dropped calls deal, not much service in the mountains, and until recently, poor coverage close to 466A in TV. If we were frogs, I'd have been yanking my hair out with their coverage issues we'd experience while we were there. But given our snowflake status, it's was more of a nuisance than a show-stopper problem.
I think all of the cell service providers have some issues. Ex.: I work around a lot of guys who have Sprint/old Nextel and they constantly curse their phones and the service. It mostly depends on where you are when you're trying to use your phone - that's what seems to be the biggest determining factor with the quality of signal/service.
JMHO!
