AT&T customer service


It is the largest wireless carrier in the United States and the world’s fourth-largest telecommunications company by revenue. As of 2023, AT&T was ranked 13th on the Fortune 500 rankings of the largest United States corporations, with revenues of $120.7 billion. During most of the 20th century, AT&T had a monopoly on phone service in the United States. The company was founded as the American District Telegraph Company in St. Louis in 1878 and expanded its services to Arkansas, Kansas, Oklahoma, and Texas through a series of mergers. It became Southwestern Bell Telephone Company in 1920, which was then a subsidiary of American Telephone and Telegraph Company.

AT&T customer service a story of vision

“We connect people to greater possibility”

The latter was a successor of the original Bell Telephone Company founded by Alexander Graham Bell in 1877. The American Bell Telephone Company formed the American Telephone and Telegraph Company (AT&T) subsidiary in 1885. In 1899, AT&T became the parent company after the American Bell Telephone Company sold its assets to its subsidiary. The company was rebranded as AT&T Corp. in 1994. The 1982 United States v. AT&T antitrust lawsuit resulted in the divestiture of AT&T’s (“Ma Bell”) local operating subsidiaries, which were grouped into seven Regional Bell Operating Companies (RBOCs), commonly referred to as “Baby Bells”, resulting in seven independent companies, including Southwestern Bell Corporation (SBC). SBC changed its name to SBC Communications Inc. in 1995.

In 2005, SBC purchased its former parent AT&T Corp., and took on the latter’s branding, history, stock trading symbol, and a version of its iconic logo. The merged entity, AT&T Inc., launched on December 30, 2005. The newly merged and renamed AT&T Inc. acquired BellSouth Corporation in 2006, the last independent Baby Bell company, making BellSouth and SBC (AT&T Inc.)’s formerly joint venture Cingular Wireless a wholly owned subsidiary of AT&T Inc.

AT&T Inc. also acquired Time Warner in 2016, with the proposed merger confirmed on June 12, 2018, and aimed to make AT&T Inc. the largest and controlling shareholder of Time Warner. It then rebranded Time Warner as WarnerMedia in 2018. However, the company later withdrew its equity stake in WarnerMedia in 2022 and merged it with Discovery, Inc. to create Warner Bros. Discovery, divesting itself of its media arm.

The current AT& T includes four of the original “Baby Bells” and the AT& T Corp.’s long-distance division, reconstituting most of the former Bell System.

Bonita Springs, FL

Great experience at AT&T Sarasota! Tom spent an hour and a half helping us convert from XR to 15Pro iPhones. We got a watch upgrade too. My work discount was applied for 20% off without me requesting it! Top-notch customer service and unsurpassed product knowledge – amazing! Thank you!

ave been with AT&T since we have owned cell phones. Today my wife and I went into an AT&T corporate store to close our accounts! Rising monthly fees with no valid explanations. We met with the sales technician, Chris Cole 8041 Dani Dr. Fort Myers FL. Chris explained and made adjustments without additional costs but saved us substantial dollars each month. We felt relieved and Chris saved us from closing our accounts!! Thank you!! Chris is a great asset to AT&T!!!!
