AT&T Inc

AT&T Inc. is a U.S. telecommunications company providing wireless, fiber-based internet, and legacy voice and data services to more than 100 million U.S. consumer and nearly 2.5 million business customers. The company operates through three segments: Advanced Connectivity, which delivers domestic 5G wireless, fiber broadband, fixed wireless (AT&T Internet Air), and advanced connectivity services to consumer and business customers; Legacy, which provides domestic voice and data services over its copper-based network, which is being systematically decommissioned through 2029; and Latin America, which provides wireless services and equipment to customers in Mexico. AT&T is aggressively expanding its fiber footprint — reaching 38.6 million locations with plans to surpass 60 million by 2030 — and growing its fixed wireless offering alongside its 5G mobile network. The company completed the acquisition of Lumen Technologies' mass markets fiber business in early 2026, further expanding its fiber reach. AT&T has divested its DIRECTV equity interest and is focused on converged connectivity, where 42.5% of advanced home internet customers also subscribe to AT&T wireless service. Updated Jul 22, 2026
