Originally, U.S. Cellular used analog, then Digital AMPS "TDMA" cell phones in most markets, but the company started shifting over to 1xRTT CDMA technology in 2003. After the switch, U.S. Cellular discontinued all analog and TDMA services. In 2009, U.S. Cellular started converting its network to EVDO which offers 3G speeds.

U.S. Cellular announced that it would start offering 4G LTE coverage to customers beginning in the first quarter of 2012.
