Vietnam’s Ministry of Information and Communications (MIC) is formulating guidelines for mobile number portability (MNP), which could be released next year, local news source Viet Nam Business News reports. ‘MNP will be definitely deployed sooner or later in Vietnam to promote fair competition amongst local mobile operators,’ an MIC official was quoted as saying. The service will enable the country’s wireless subscribers to retain their number when changing from one network operator to another. However, the country’s largest cellco by subscribers Viettel has expressed its reluctance in implementing the service: ‘We have just poured a lot of money into 3G infrastructure and the market segment has not yet matured to apply the MNP policy, as it would not benefit such operators like us,’ stated Nguyen Manh Hung, deputy general director of Viettel Group. According to TeleGeography’s GlobalComms Database, Vietnam was home to over 120 million wireless subscribers at 30 September 2010, an increase of 20% compared to 99.7 million twelve months previously.
