At present, there are 4 ouf of 5 telecom services providers in Vietnam, which are committed to implement the service, such as: MobiFone, Viettel, Vinaphone, and Vietnammobile. The feature of keeping existing phone number while switching service provider will create opportunities for services providers with better service quality gaining customers. However, which services providers can take this chance remains to see.
In terms of infrastructure, no doubt Viettel has the biggest advantage with the largest mobile network, in which its 3G network has covered across the country, while Viettel has taken the lead in the race of 4G network coverage. Moreover, Viettel has always come ahead of other services providers in new customer development and attracting customers from competitors. For Vinaphone, the most obvious advantage of this services provider is the high number of loyal customers as one of the first telecom service providers in Vietnam. However, having to share the infrastructure with MobiFone, the network coverage of Vinaphone is hard to compare with Viettel, which is also the disadvantage of this service provider.
MobiFone is the service provider with the lowest rate of subscriber development comparing to Viettel and Vinaphone. As such, in the period of 2013 – 2016, among the three biggest telecom service providers in Vietnam, only MobiFone has the market share being reduced from 31.78% to 26.1%. Moreover, the network coverage of MobiFone is much smaller than the other two service providers. Vietnamobile – with 2.9% market share in 2016, there is a small chance for them but is not expected to gain more customers than as of present. With no restriction to promotion events like leading telecom services providers, and the most reasonable internet fee among others are the only advantages of this telecom service provider to attract students and low income customers.
