AT&T Inc. operates primarily through two business segments: Communications and Latin America. The Communications segment, which accounts for the vast majority of revenue, provides wireless voice and data communications, broadband fiber internet, and legacy wireline services to U.S. consumers and businesses. The Latin America segment offers wireless services and equipment in Mexico. Historically a conglomerate with significant media holdings, AT&T divested its WarnerMedia and DirecTV businesses to refocus on its core telecommunications infrastructure. The company is currently investing heavily in expanding its 5G wireless coverage and fiber-optic network footprint across the United States.
