We have AT&T but mostly because of friends and family have it as well so we to get charged against our minutes for calls. Coverage in the North Georgia mountains is spotty gets better when you get south a bit. But can't really advise other than to say try to get them to give you a booster or better phones because it really depends on who has the most cell towers in your area. Here in our part of Georgia if you have anyone other than AT&T or Verizon you don't get service. had Nextel/ Sprint once and couldn't get a signal unless you where whithin 50 miles of ATL.
GOOD LUCK.
