Staying connected in Vietnam
What the coverage maps do not tell you, and what you will actually use the data for.
Where the signal actually drops
Viettel, Vinaphone and Mobifone cover the country well and cheaply, including most of the coastal route. The gaps are the northern mountains around Ha Giang and Sapa, where signal follows the valleys, and parts of the central highlands. Ha Long Bay cruises lose signal out on the water.
What you will use your phone for here
Grab is the default for both taxis and food, and motorbike taxis are booked the same way. Translation is used constantly, and QR payment through local apps is spreading fast.
Before you go
The Ha Giang loop and similar mountain routes are genuinely off-grid in places, which matters because they are also where a breakdown is most likely.
How much data you will actually need
Moderate to high, driven by Grab and maps.
