América Móvil announced plans to sell the majority interest (over 50%) of its operations in Mexico in order to cease being a "preponderant economic agent" as defined by new laws intended to break up the telecom monopolies in the nation.
The intended sales concern América Móvil's fixed line business, TelMex, and its mobile network, Telcel. Carlos Slim is the largest stakeholder in América Móvil.
As part of the plan, all cellular cites (base stations), including towers and related passive infrastructure, will be separated from Telcel so that they may serve on a wholesale basis to all interested parties.
América Móvil's TelMex division also ratified a commercial agreement with Dish México in anticipation of offering pay television service once its regulated status as preponderant economic agent is cleared.
