The official results of quality checks on the stability and speed of 4G mobile Internet services offered by two major carriers in Vietnam have been released.

The results, announced on Wednesday, showed that MobiFone and Viettel lived up to benchmarks issued by the Authority of Telecommunications, the agency responsible for conducting the tests.

The 4G services were tested on five indicators: the availability of the wireless network, access success rates, average latency time, data transfer drop rates, and data upload/download speeds as recorded in Hanoi.

Military-run telecom giant Viettel had their 4G service tested between June 8 and 16, scoring 100 percent in network availability and 0.65 percent in drop rates.

The average download speed using Viettel’s 4G Internet was 34.9 megabits per second, while the average upload speed was 16.88 Mbit/s.

MobiFone’s 4G service, which was tested between July 19 and 26, demonstrated 99.98 percent network availability in Hanoi and a drop rate of 0.74 percent.

The provider’s average 4G download and upload speeds were 36.91 Mbit/s and 19.28 Mbit/s, respectively.

The report by the Authority of Telecommunications, published on its website on Wednesday, did not include Vinaphone, the country’s third major mobile service provider.

In the State of the Internet Report issued by American content delivery network Akamai Technologies earlier this year, Vietnam’s average mobile Internet speed in the first quarter of 2017 was recorded at 5.3 Mbit/s.

The performance was much slower than the regional average of 9.69 Mbit/s, according to the same report.
