Cingular Wireless LLC is the largest mobile phone company in the United States. Its corporate headquarters are located in Atlanta, Georgia, United States.

Cingular was formed in 2001 as a joint venture of the American landline telephone companies AT&T (then known as SBC Communications) and BellSouth. These two companies still hold 60% and 40% stakes in Cingular, respectively, proportionate to the assets that each company contributed to the venture.

Since it's formation, Cingular has put a lot of work into building up the Cingular Wireless brand, and has managed to achieve the status of America's most popular wireless network. With healthy competition from arch-rivals, Verizon and Sprint, this is indeed quite an accomplishment.

As with any wireless carrier, Cingular puts a lot of time into deciding which phones will sell best on their network. They work with handset makers like Motorola and Nokia to come up with the best and most user-friendly Nokia cell phones and Motorola cell phones for use on the Cingular network.
