Editors' note: Because evaluating wireless coverage requires experience with the network in a wide variety of physical locations, CNET does not rate wireless carriers. We can, however, tell you everything you need to know about the major carriers. We invite your feedback and ratings in our user opinions section--the more input we get from around the U.S., the better our users can evaluate coverage at a national level. For more carrier information, please see CNET's Quick Guide.
