Vietnam’s three largest mobile network operators (MNOs) by subscribers, Viettel, MobiFone and VNPT-Vinaphone, have begun testing mobile number portability (MNP) on their networks, bringing a launch of the long-delayed service one step closer. Tuoi Tre News reports that MNP is expected to become officially available in Vietnam on 31 December, enabling consumers to retain their number if they switch service provider. According to draft regulations, subscribers are required to have used their number for at least 90 days with their current provider before they can apply for a transfer.
TeleGeography’s GlobalComms Database states that the Ministry of Information and Communications (MIC) signed a decision in September 2013 approving the introduction of MNP from the start of 2017, with the aim of improving competition and promoting the development of the mobile market. However, following concerns from operators that they would require more time to prepare their networks, MNP is now scheduled to be introduced at the end of this year.
