content: I manage a 125 user cell account spread across the US where I work. When negotiating a new contract last year we got test phones from all of the major carriers to test. Here was our results: T-Mobile - cheapest, unusable bad coverage Sprint - expensive, unusable bad coverage AT&T and Verizon were about the same. About 20% more than T-Mobile, but the best coverage. In the end Verizon gave us a lot of money in credit so we went with them.
