Sprint is one of the biggest cellular providers in the United States, and their popularity has only grown since they merged with Nextel to offer even more diverse services and better coverage areas. As such, many people who live in areas where Sprint has extensive coverage choose this company for their cell phone service. Having been around for quite some time in both cellular and landline communications, Sprint is a company that knows a thing or two about how important phone calls are for people and they generally provide extremely reliable service.
