Interconnection charges, such as the fees fixed line operators pay to mobile operators for termination of calls, make tariffs more expensive than necessary, according to Ruiz, who used to be the general manager of telecommunications regulator Osiptel. A fixed interconnection charge should help to promote fair competition and service coverage expansion, Ruiz said.

"Nextel would be highly benefited if a low interconnection charge is approved, because it operates as a call exporter, making more calls than it receives, but it would not be as convenient for TIM or Telefónica since their networks receive a large number of calls," Ruiz said.

In Peru, interconnection charges for connecting a call to a mobile network represent 60% of rates charged to end users.
