Since the takeover of AT&T Wireless by its competitor Cingular, AT&T Mobility has been one of the largest wireless companies in the United States with approximately 77 million customers and competes with T-Mobile US , US Cellular and Verizon Wireless . On January 15, 2007, the company name was changed from Cingular to AT&T Wireless. This move has been criticized by many Americans because the company spent millions between 2005 and 2006 to integrate AT&T Wireless with Cingular.

By the end of December 2000, 60 percent of the shares in Cingular were owned by the large regional fixed line telecommunications provider SBC Communications and 40 percent by the regional telecommunications group Bell South (Southeast States). With the takeover of Bell South by SBC, which had already renamed itself to AT&T in 2006, the reason for the use of the name Cingular ceased to exist. Like its competitor T-Mobile US, Cingular uses the GSM cellular standard .

AT & T Mobility used in addition to the many Triband used cell phones standard PCS 1900 additional GSM 850. The lower frequency allows a wider distribution of the signal, which is used especially in rural areas of the United States. Some regions, such as large parts of Ohio , are completely covered by GSM 850, so that you only have unrestricted reception in international roaming with a quad-band mobile phone. At New York's John F. Kennedy Airport, GSM 850 coverage is better than PCS 1900.

The UMTS network also deviates from the European standard.

Strategic partnerships

The company Apple was already before the acquisition a strategic partnership with Cingular to market the new Apple iPhones received.
