AT&T Mexico Overview
AT&T Mexico is Mexico's second-largest mobile operator and a wholly owned subsidiary of AT&T in the United States. It offers mobile service, fixed broadband, and enterprise services in Mexico, with about 25 million users. It is the only Mexican operator run directly by a US carrier. For companies that span the United States and Mexico, North American supply chains, and manufacturing shifts out of the US, AT&T Mexico and the AT&T US network can be managed together for roaming and IoT connectivity.
In 2015, AT&T acquired the Mexican operators Iusacell and Nextel Mexico, integrating them into AT&T Mexico and beginning its expansion in Mexico. Over ten years, the user base grew from about 8.6 million to nearly 25 million, with a compound annual growth rate of approximately 12%, making it one of the fastest-growing operators in Mexico.

Development History and Milestones
The predecessor of AT&T Mexico can be traced back to the Mexican operators Iusacell and Nextel Mexico. Iusacell was established in the 1990s and was one of Mexico's early mobile operators; Nextel Mexico used iDEN technology, focusing on enterprise and push-to-talk services. The 2014 Mexican telecom reform broke the América Móvil monopoly, creating opportunities for foreign investment.
In 2015, AT&T acquired Iusacell and Nextel Mexico for approximately $4.4 billion, integrating them into AT&T Mexico, as part of AT&T's "North American Mobile Network" strategy. AT&T invested heavily in building a 4G LTE network to cover major cities in Mexico. In 2018, AT&T Mexico launched a 4.5G network, and in the 2020s, it promoted 5G deployment. In 2020, AT&T spun off its Mexico business from WarnerMedia, but Mexico operations remained a core AT&T asset. In 2025, AT&T Mexico had 24.68 million users and revenue of approximately $4.8 billion, an increase of 3.5% year-on-year.
