History

Cingular Wireless was formed in 2001 as a joint venture of SBC Communications (now AT&T) and BellSouth. The joint venture created the nations second largest carrier. Cingular grew out of a conglomeration of 11 regional companies. these companies include BellSouth Mobility, BellSouth Mobility DCS, Cellular One, Houston Cellular, BellSouth Wireless Data, Southwestern Bell, Pacific Bell, Nevada Bell, Ameritech Cellular, SNET and SBC Wireless. With the exception of Pacific Bell and BellSouth Mobility DCS, the digital network consisted of TDMA Technology. The Pacific Bell and BellSouth Mobility DCS networks used GSM technology on the PCS frequency (1900 Mhz). In 2002 Cingular began an initiative called "Project Genesis" which the code name for the GSM/GPRS overlay of the entire network. Project Genesis was completed by the end of 2004.

After a bidding war with Britain's Vodefone PLC, Cingular announced in February, 2004 that they would purchase AT&T Wireless for 41 Billion dollars. The merger was completed on October 16, 2004. The combined company had a customer base of 46 million people which placed Cingular as the largest wireless provider in the United States.

GSM Facilities

In California, Nevada, North Carolina, South Carolina, eastern Tennessee, eastern and coastal Georgia, northern New Jersey and New York City, Cingular and T-Mobile USA maintained and shared a GSM-1900 network prior to the acquisition of AT&T Wireless, through a joint venture known as GSM Facilities. The network sharing agreement allowed Cingular to offer local service in northern New Jersey and New York City and T-Mobile to offer service in California and Nevada. On May 25, 2004, Cingular and T-Mobile USA announced their intention to dissolve the agreement contingent on Cingular's successful acquisition of AT&T Wireless.

First announced on June 23, 2005 Cingular Wireless announced the intention to divest its Caribbean and Bermuda operations and licenses which it acquired from the acquisition of AT&T Wireless, to Bermuda-based Digcel Group under undisclosed financial terms.

Cingular outsources some of their Customer Care to companies in Canada and overseas.

On August 25, Cingular was removed from the New York Better Business Bureau because of a large number of complaints that were not handled in a timely manner. The company is in the process of restructuring its customer care procedures and has appealed the decision. It remains a member of the BBB in other states in which it operates.

In 2004, the Federal Communications Commission (FCC) reported logging more than 14,000 complaints (or 289 per million subscribers) against Cingular Wireless. The most common of which included number portability issues, over billing, poor customer support and network reliability.

Possible Name Change

On 20 November 2005, Ed Whitacre, CEO of the newly-merged SBC/AT&T, announced plans to market the service under the AT&T banner. BellSouth spokesman Jeff Battcher countered that the terms of the joint venture allow either party to sell the service under another name, and that he believes they will be using the brand to market to business customers. Cingular president Stan Sigman concurred with BellSouth's position, indicating that the Cingular brand would continue but be sold under the AT&T brand where offered in packages with other AT&T services, such as data and wireline telephony.

Adelante

Recently, Cingular has launched a new ad campaign "Adelante". In Spanish it means literally "forward". It is aimed at the Hispanic and Spanish speaking communities in the U.S. to boost sales and consists of newspaper ads, commercials, and magazine ads. Also, part of "Adelante" is to now start offering bilingual support at its stores for English and Spanish.

Trivia

  • A sales boost is expected following January 2006, when RadioShack (the top wireless retailer in the US) will no longer sell Verizon phones and instead will sell Cingular phones.
  • Cingular Wireless is the wireless carrier of the street racers in Electronic Arts' street racing video games Need for Speed Underground 2 and Need for Speed: Most Wanted. It is used to receive SMS messages from other racers.
