Mexico’s anti-trust body, the Federal Competition Commission (FCC), is considering imposing new pricing regulations on the country’s mobile operators. The body published the preliminary findings of its investigation into mobile call completion fees this week, concluding that the operators wielded “substantial power” in the completing of calls to their networks and hinted that further regulation may be necessary to stop abuse. “Each operator has the capacity, unilaterally, to restrict calls to their network,” the Commission said, adding that new regulations could be required to “avoid the abuse of this power in detriment of the efficiency of the markets and the welfare of consumers.”

The Commission named America Movil (Telcel), Telefonica Mexico, and smaller operators Iusacell and Unefon as the companies that could be affected. According to Wireless Intelligence data, America Movil is the country’s market-leader with around 51.5 million connections by first-quarter 2008. Telefonica is second-placed with 13.3 million.
