Why Choose AT&T?

AT&T is one of the major carriers here in the United States. It is known as a mobile network operator, or MNO, because it builds and maintains its own cellular network. AT&T purchases spectrum licenses, builds or leases cell towers, and develops its own network infrastructure. AT&T will also lease access to its cellular network to smaller carriers at wholesale rates.
