Staying online in Vietnam — tips

Does eSIM work in Vietnam?
Yes — Vietnamese networks support eSIM, and a travel eSIM activates over Wi-Fi before arrival, provided your phone is eSIM-compatible.

Not a physical one — a travel eSIM gives data on arrival without the airport counter, while keeping your home number for messages.
Network names and coverage are general guidance and can change; eSIM compatibility depends on your specific phone model, not the country. Live plans, prices and data allowances are shown on the provider’s site. Check your handset supports eSIM before purchasing.
