## About Unefon

AT&T Mexico, operating under the Unefon brand, is a major mobile network provider in Mexico, situated within the North America & Caribbean region. Identified by the Mobile Country Code (MCC) 334 and Mobile Network Code (MNC) 80, Unefon leverages AT&T's global infrastructure to deliver cellular services across a significant portion of the Mexican Republic. AT&T's presence in Mexico provides a comprehensive mobile experience, offering both prepaid and postpaid options with a focus on providing competitive data packages and reliable network coverage, particularly in urban areas and major roadways.

Unefon initially operated as a separate entity before being acquired by AT&T. In leveraging AT&T's resources, Unefon aims to compete effectively with other major mobile network operators such as Telcel, owned by América Móvil, which traditionally holds a dominant market share in Mexico. The competition between these providers has driven innovation and improved accessibility to mobile services for Mexican consumers. AT&T's efforts, often through the Unefon brand, contribute to increased network coverage and adoption of advanced technologies like 4G LTE and the ongoing deployment of 5G across the country, facilitating improved connectivity for both personal and business use.
