The move forms part of its measures to open up competition in the market and reduce the dominance of Carlos Slim's America Movil.
America Movil SAB de CV is reportedly able to charge companies that use its network between 0.005162 pesos and 0.006246 pesos.
Its rivals in the market, such as Telefonica and Nextel, are exempt from the measures and can charge a much higher 0.2505 pesos.
In mid-July, the Mexican government finalised sweeping reforms to the country’s telecoms market, in a bid to end Slim’s hold on the market and attract new investors.
The reforms included that any player deemed dominant in the market must reduce its share in both the mobile and fixed-line markets, as well as slash the price it charges competitors to use its network infrastructure.
AT&T has since been rumoured to be interested in entering the market.
