I really like AT&T, Iive in Ridgecrest, CA, and the service here, especially since live in the desert area. I have the prepaid plan on AT&T, so I am only paying $60 a month, and I still get regular coverage as if I am on the regular post paid account. The call quality is great, its always crisp clear voice, and never lost a call once. I used to have T-Mobile, but their service was not as good as AT&Ts, and there is not much coverage out here for any other carriers. I get 4G lte, and super fast speeds with my S7 edge. AT&T customer service is really good about helping you with any problems you are having, and have always received the help I would ask for.
