Thee major telecom network providers Viettel, VinaPhone and MobiFone started testing mobile number portability (MNP) on Thursday, which allows subscribers to keep existing mobile number when switching networks.
Late last week, Vietnamese Prime Minister Nguyen Tan Dung asked the
Ministry of Information and Communications to look into possible
regulations restricting free call and messaging apps (chat apps) in an
attempt to level the playing field for Vietnamese telecoms companies.
