About Vietnam eSIM coverage
Coverage & Networks
4G/LTE via Viettel, Vinaphone and Mobifone; 5G pilots in Hanoi and Ho Chi Minh City — Reliable in Hanoi, Ho Chi Minh City and all main tourist hubs. Ha Long Bay boat trips and highland areas like Sapa and Ha Giang can have weaker 4G.
How much data do I need?
Vietnam is a long country and travel-heavy itineraries use data steadily. 3–5GB suits a two-week north-to-south trip — translation, booking apps and navigation all run regularly across the distances.
Tip for Vietnam
Ha Long Bay cruises book up fast, especially overnight tours from March to October. Confirm your operator and departure details thoroughly before leaving Hanoi — the quality difference between operators is significant.
