Viettel has established a big lead in 4G Availability
With a score of 86%, Viettel stood head and shoulders above its rivals in our 4G Availability metric. Second-place finisher Vinaphone was 10 percentage points behind the leader in our analysis, while MobiFone and Vietnamobile both scored below 70%. Viettel has clearly deployed a much more accessible 4G service, according to our measurements.
Huge variations in average speed exist among Vietnam's operators
While we often see a range of speeds across a country's different operators, in Vietnam the differences between fastest and slowest average connection speed is quite stark. The leaders in our Download Speed Experience and Upload Speed Experience categories averaged connections four-to-five-times faster than the last placed finishers, according to our analysis.
Video Experience ranges from Poor to Good in Vietnam
Depending on the operator, the typical Video Experience in Vietnam can vary from Poor, in which case video is very slow to load and experiences frequent interruptions, to Good, where video loads much more quickly and stalls much less often.
Viettel is the operator to beat in nearly every metric
Though Viettel's biggest lead was in 4G Availability, it outdid its peers in nearly every single one of our metrics, also winning our Video Experience, Download Speed Experience and Latency Experience awards outright. In the final metric, Upload Speed Experience, Viettel shared the award with Vinaphone as both operators averaged upload connections of 6.1 Mbps.
