I had Verizon while working but went to AT&T since. The maps show AT&T has better coverage but I had better performance with Verizon. In the Arcadia Valley I have a cell amp but coverage is less than ideal. And while at Mark Twain Lake when my buddy Bob dropped my truck key in the lake we were calling around to get someone to bring my spare key. We could see three towers but could not make a call. We both have AT&T.
