Coverage will vary. When we moved here (Amelia) in 08 we had Verizon and had good coverage. With more new customers the service became spotty. Swithched to ATT after 2 years it became spotty then back to Verizon after 2 years they again became spotty. Last year ATT added towers, I think and we switched to Consummer Cellular, they use ATT towers and it works.

Best part Consummer Cellular is no contract, month to month. If it stops working we will switch again. We have always ported our number so we keep our old number.

Consummer cellular, I think, Has the best pricing and the plan can be changed instantly if you find you are going to run over. You can program the service to warn you if you are comming close. We pay $44.61 per month for two phones/lines. 600 min/1000 text and data. That,s a medium cost plan more minutes are available.

To answer your question for us ATT has been good all over TV for right now.
I think they, Comsummer Celular, have a 100% guarantee no charge return if it doesn't work for you. Check out the web site.

I had a sprint, not happy so I bought and signed up for verison. No bars at home but if I drove my golf cart around with it, I got more bars a few blocks from home. I took it back. I guess I am in a dead zone. My son visited me here and got good reception with a galaxy 5 through at&t. I ended up just going with a contract free boost phone. I don't want to pay the money required to get a good signal. I go outside if it is a problem which it usually is.
