How to choose the right plan
- Light use — maps, messaging and browsing — needs about 1 GB per day.
- Heavy use — social video, streaming or hotspotting a laptop — plan for 2-3 GB per day or pick the largest plan.
- Match the validity to your trip length, with a day or two of buffer for delays.
How activation works
- Buy the plan and receive your eSIM by email within minutes.
- Install it from your phone settings while still at home — no store visit, no plastic SIM.
- Land in Vietnam, enable the eSIM line, and you are online before leaving the airport.
All Vietnam eSIM plans
Grab bookings, translation apps and train tickets make data the most useful thing in your pocket in Vietnam. An eSIM activates before you land in Hanoi or Ho Chi Minh City and costs less than an airport coffee.
Grab, Google Translate and a pin in an alley with no street number: Vietnam runs on data. An eSIM is cheaper than the airport SIM and means your first xe om is a tap, not a negotiation in arrivals.
