Vietnam travel Wi-Fi: share a hotspot in Hanoi, Da Nang, Ho Chi Minh City
One local SIM or eSIM, the whole family online from Hanoi to Phu Quoc.
Local SIM cards and travel eSIMs for Vietnam are easy to get, often right at the airport. Put one in a phone, turn on its hotspot, and everyone else can share it.
Cities and beaches
Hanoi, Ho Chi Minh City, Da Nang, Nha Trang and Phu Quoc are popular stops with good city coverage — ideal for ride-hailing, maps and translation.
Grab, maps and payments
Ride-hailing and maps need a constant connection. A hotspot keeps the whole group's phones online, not just the one with the SIM.
Islands and mountains
Coverage can be weaker on boat trips and in mountain areas such as Sapa or Ha Giang. Download maps in advance.
Heat and battery
Hot weather plus a hotspot warms phones quickly. Keep the host phone out of direct sun and carry a power bank.
Quick tips
- Choose a SIM or eSIM plan that allows tethering.
- Keep the host phone shaded on hot days.
- Share the hotspot QR in the hotel on arrival.
Questions
Is a local SIM better than roaming in Vietnam?
Often cheaper for data, but it changes your number. Compare your carrier's roaming pass with local or eSIM options.
Does a hotspot work on island tours?
Near the coast usually yes, further out at sea coverage drops.
Can I use the QR code offline?
Yes — joining Wi-Fi by QR needs no internet.
