Nextel Mexico says that just one of Mexico’s four cellular mobile operators has complied with the regulator’s order to allow their users to exchange SMS with its own customers. On 12 January the Comisión Federal de Telecomunicaciones (Cofetel) ordered the nation’s GSM and CDMA network operators to exchange text messages with iDEN operator Nextel. Cofetel gave Iusacell, Telcel, Unefon and Telefónica Móviles México ten days to ink agreements and 60 days to make its SMS services compatible with those of Nextel, after the latter filed a complaint with the country’s antitrust committee last year. But according to Dow Jones Newswires, Nextel’s VP Gustavo Cantu says the company has thus far only reached an agreement and begun technical tests for exchange of SMS with Telefónica Móviles. Telcel in particular has been critical of Cofetel’s ruling, saying that Nextel’s operating concession is for trunking services and that it should not be considered a true wireless operator.
