Currently in the US cellular phones use either analog service or digital service. Most new cellular phones use digital technology. Currently three digital wireless technologies are used in the USA: TDMA (Time Division Multiple Access), CDMA (Code Division Multiple Access), and GSM (Global System for Mobile Communications). Unfortunately, many times digital cellular phones may work with only one technology: TDMA, CDMA, or GSM.
