(Telecompaper) El Salvador's antitrust regulator Superintendencia de Competencia has provisionally approved America Movil's request to acquire Telefonica's operations in El Salvador on acceptance of a series of anti-trust conditions. In a statement, the watchdog cautioned that Claro El Salvador's increased market share could give rise to "limits on competition" and the operator must therefore rule out the future use of spectrum currently used by Telefonica's Movistar unit in the country. The portions include 25 MHz with national coverage in the 850 MHz band and a further 30 MHz in the 1900 MHz band.
