Provider Comparison for Vietnam
Each provider uses different local networks in Vietnam, resulting in different coverage quality and speeds. Here is how they compare.

Viettel provides the widest coverage across Vietnam, including remote areas. 4G is fast in cities but can be patchy in mountainous regions.
Vietnam has 3 major mobile networks: Viettel, Mobifone, Vinaphone. The best coverage comes from Viettel, which covers 96% of the population with 4G and 5G technology.

Tips for Using eSIM in Vietnam
Download maps and content before your trip
Even with great coverage in Vietnam, having offline maps (Google Maps, Maps.me) saves data and works in areas with weak signal.
Monitor your data usage
Check your data usage in phone settings regularly. If you are running low, most providers let you purchase a top-up or additional plan without losing connectivity.
Choose the right network for Vietnam
Viettel offers the best coverage in Vietnam. If you plan to travel outside major cities, prioritize providers that use this network.
Disable automatic updates
Turn off automatic app updates and cloud photo syncing to conserve data. These background processes can consume gigabytes without you noticing.
Test your eSIM before departure
Install the eSIM profile while on WiFi at home. Some phones let you verify the profile is correctly installed without activating the data plan, so you know everything will work when you land in Vietnam.
