, they are truthful when they claim that their system was built from the ground up. Only their phones use their Personal Communication System (PCS) towers, and many of their phones do not operate on an analog signal at all, and those that do must use the towers built by other companies. For this the user is charged thirty-five cents for each minute spent outside of the Sprint PCS network.
