Every Cingular cell phone uses the latest phone technologies like TDMA network and GSM/GPRS. In 2003, Cingular introduced the Enhanced Data rate for GSM Evolution (EDGE) technology. Universal Mobile Telephone Service (UMTS) was also introduced. UMTS allows global roaming, and is the natural evolutionary path for the GSM/GPRS technology. All the Cingular cell phones display multimedia messaging, ringtones, and graphics capabilities.

Cingular cell phones enjoy a strong market in the United States. This company has marketing tie-ups with major cell phone manufacturers and the widely used term "Cingular cell phones" does not actually mean that the company Cingular Wireless manufactures the cell phones; it only provides network services for the major brands of cell phones.
