Viettel Mobile stands out in Vietnam’s Mobile Network Experience
In Opensignal’s third report on Vietnam’s Mobile Network Experience, one mobile operator continues to remain head and shoulder above its rivals. Viettel Mobile won several awards by a large margin including 4G Availability, 4G Coverage Experience, Download Speed Experience and Upload Speed Experience. Although other mobile operators came close to challenging Viettel in a few categories, only Vinaphone managed to share first place with Viettel in Latency Experience. Viettel also won our Voice App Experience and Video Experience awards, by achieving a Good rating in Voice App Experience and a Very Good score in Video Experience.
Viettel Mobile dominates 4G Availability and 4G Coverage Experience
Viettel Mobile held fast its 4G Availability award, and remains the clear leader with an average score of 89.7%, though its rivals have worked hard to close the gap over the past six months. MobiFone and Vinaphone have also surpassed the 80% milestone with users being able to spend at least 16.5% and 12.7% more time connected to 4G on their respective networks. At the same time Viettel also won our inaugural 4G Coverage Experience award in Vietnam with 8.1 points (on a scale of 0-10). This metric analyzes the locations where customers of a network operator received a 4G signal relative to the locations visited by our users of all network operators.
Video Experience hits Very Good for three out of four networks in Vietnam
Video Experience in Vietnam is getting better: users on all four national networks of Vietnam have seen notable improvements in Video Experience since the last report. While Viettel won the award in this category with a score of 71.3 points (on a scale of 0-100), Vinaphone came closer to challenge the leader with 70 points, and MobiFone trailed closely behind at 67.2. With increases of 10.6%, 19.5% and 19.3 % in the last six months respectively, all three operators have moved into the Very Good range, meaning users on these networks now enjoy generally fast loading times with only occasional stalling while streaming video services on their smartphones. That said, the highest increase was recorded on Vietnamobile’s network: with a score of 44 points, their users’ Video Experience moved from Poor (under 40) to Fair, — an increase of 25.8% since the last report.
Viettel Mobile’s overall Download Speed Experience grows to 24 Mbps
Viettel sprinted to increase its overall Download Speed Experience score by 5.5 Mbps since our previous report and passed the 20 Mbps marker. The operator’s award-winning score of 24 Mbps gave it a convincing lead over its peers. Our users on Viettel experienced average speeds 12.4% faster than Vinaphone’s score of 21.3 Mbps, 38.7% faster than MobiFone’s score of 17.3 Mbps, and five and a half times faster than Vietnamobile’s score of 3.71 Mbps.
Viettel Mobile sweeps away the Upload Speed Experience Award
Our users on Viettel Mobile witnessed an impressive 3.7 Mbps gain compared to our last report, taking the average Upload Speed Experience to 9.6 Mbps. In our last report, Viettel was tied with Vinaphone, but since then it has broken the deadlock and raced past its competitor to win the award outright. Viettel Mobile users saw download speeds that on average were 15.9% higher than those observed by their Vinaphone counterparts. However, users on Vinaphone and MobiFone also observed significant improvements: 4.3 Mbps and 3.3 Mbps respectively
Viettel Mobile wins our first Voice App Experience award in Vietnam
Opensignal's new measure of Voice App Experience quantifies the quality of experience for over-the-top (OTT) voice services — mobile voice apps such as WhatsApp, Skype, Facebook Messenger, etc. We saw three operators MobiFone, Vinaphone and Viettel — vying to win the award in this category. While all three of them garnered Good ratings (80-87 out of 100), Viettel won the first Voice App Experience award in Vietnam. A Good rating means that many users are satisfied, while some users experienced minor quality impairments during their calls. On the other hand, the fourth operator, Vietnamobile, who was separated by more than 10 points from the front-runners, ended up in the Poor rating (66-74) bracket — meaning calls will be marred by frequent distortion, clicking sounds or silence, leaving many users dissatisfied.
