Telcel holds concessions to operate a wireless network in all nine geographic regions in Mexico using both the 850 megahertz and 1900 megahertz radio spectrum. According to Cofetel (Comision Federal de Telecomunicaciones—Mexico's Federal Telecommunications Commission), as of July 2008, Telcel's subscribers represented an estimated 77.2% share of the Mexican wireless market. Telcel is the largest wireless carrier in Mexico, with 77.2 million subscribers as of March 2020. Voice services

Telcel provides services in AMPS, GSM, and TDMA, as well as the newer technologies of UMTS and WCDMA. Because of the wide base of older technologies like TDMA and AMPS they are still in use. Telcel offers voice services under a variety of rate plans to meet the needs of different market segments. The rate plans are either postpaid, where the customer is billed monthly for the previous month, or prepaid, where the customer pays in advance for a specified volume of use over a specified period. Telcel believes the prepaid market represents a large and growing under-penetrated market in Mexico. Telcel also offers several prepaid plans, none of which includes activation or monthly charges. Prepaid customers purchase a prepaid card for a specific amount of airtime and also receive additional services such as voicemail and caller ID. As part of its prepaid service offering, Telcel provides new customers with an Amigo Kit, which includes airtime, a handset, a charger and other accessories. Customers with prepaid plans can recharge credit from anywhere in the world, just by using the official Telcet site, or any other multilanguage recharge companies. Telcel is now one of the most used phone companies from Latin America, its economy increased by 2.9% on the first semester of 2019 (+7.7% compared to Mexican GNP). However, competitors complain about monopolistic actions, given the current situation of recession for all of them but Telcel. Prepaid customers are often unwilling to make a fixed financial commitment or do not have the credit profile to purchase postpaid plans. Prepaid plans serve the needs of distinct consumer segments such as the youth market, families, customers with variable income who otherwise would not be able to obtain service due to their credit profile, and customers who prefer to pay in cash. Prepaid customers also include parents who wish to control costs for their children. In November 2006, an American embassy cable released via WikiLeaks listed Telcel among "Mexico's monopolists", with a market share of 80% of cellular service. Telmex was listed with a market share of 95% share of landlines. Push-to-Talk services
