According to the results of the latest test administered by the Ministry of Information and Communications, MobiFone is still in the lead for mobile service quality, though the gap between it and Viettel has narrowed.

This time the MoIC’s Quality Control Agency measured the service quality of three GSM mobile networks in Hanoi and two CDMA networks in HCM City.

Notably, all mobile networks exceeded the national standards on the 2008 test while in 2007, some networks failed to meet Vietnam’s criteria.

MobiFone ranked first for voice quality, followed by Viettel and VinaPhone. The ratio of failed calls for MobiFone was also the lowest. This network was also tops in ratio of successful calls to Call Centre. Viettel and VinaPhone ranked second and third in these categories, respectively.

For CDMA networks, S-Fone ranked first in all categories, followed by EVN Telecom.

On paper, MobiFone ranked second after EVN Telecom for the ratio of client complaints; however, MobiFone has more than 31 million subscribers while EVN Telecom has less than 1 million.

In 2007, MobiFone ranked first in all criteria and the gap between MobiFone and its rivals was quite large. But in 2008, the gap was narrowed considerably.

Experts say that this year competition among mobile networks will be not only in terms of technical aspects but in all aspects, including customers’ preferences.
