LG Uplus and Viettel Launch 5G Roaming in Vietnam
Specifically, according to the result measured by Speedtest software in a 5G roaming service test with partner LG Uplus, the download speed reached 72.4 Mbps, which was at an almost optimal level on Viettel’s current bandwidth and is about 10 times as fast as data velocity via 4G/LTE roaming (only 5-10 Mbps) on average.
Previously, Viettel had also become the first network operator in Vietnam to successfully roll out VoLTE service with roaming partners to provide voice service over a data network on the IMS (IP Multimedia Subsystem) technology platform; therefore, the user’s experience was enhanced by applying HD-quality calls. Especially with LG Uplus, voice connection time from Vietnam to South Korea was shortened to only 1-3 s, equivalent to only a fifth of the connection time of a normal voice call (8–10 s). Along with this technological upgrade, customers are able to enjoy high-quality HD voice calls as well as the superior speed of 5G roaming data.
As such, Viettel is not only pioneering the deployment of infrastructure networks and successfully testing 5G service in Vietnam, but Viettel’s 5G technology has also reached an international level by meeting the quality standards of LG Uplus, which is even more remarkable because Korea is one of the leading countries in 5G implementation using the most advanced technologies in the world. This is also the basis for confirming that Viettel can provide worldwide partners with a high-quality 5G roaming service.
Thanks to the aforementioned success, Viettel has finished preparation for the 5G roaming explosion right after the domestic 5G infrastructure deployment is licensed and carried out, in order to serve the great national purpose of promoting the process of becoming a 4.0 industry and globalization and multi lateralization economy, welcoming millions of international visitors to Vietnam in the era of mobile connectivity and the Internet of things in the period 2020 – 2030.

Note: The main reason for the difference between 5G roaming data speed and domestic roaming data velocity was that a limit had been set by LG Uplus on the roaming customer profile to avoid incurring high charges because of the extremely fast speed.
