Renowned as the gold standard for high-bandwidth international travelers and remote workers, 5G80M delivers 5GB of unthrottled high-speed 5G data per day on Vietnam’s premier telecommunications network.

1. What is the Viettel 5G80M Tourist Plan?
5G80M is an official prepaid data package engineered directly by the military-owned telecommunications group Viettel. Unlike generic international roaming eSIMs that route your traffic through Hong Kong or Singapore (causing high latency of 200–400ms), 5G80M connects you straight to local Vietnamese cell towers with ultra-low latency (under 25ms).
With 5GB daily, you can comfortably stream 4K videos, conduct Zoom business conferences, backup travel footage to Google Drive, and run continuous Google Maps and Grab navigation without fearing mid-day data cutoffs. Even after reaching the generous 5GB daily ceiling, data stays connected at basic speeds until your quota resets at midnight local time.
