What to know about mobile data in Vietnam

Vietnam switched off 2G on the mainland in October 2024, after a short extension of the original September date, and the government has set September 2028 as the end for 3G. So the country is moving to 4G and 5G only. The shape of Vietnam matters: it is long and narrow, with mountains in the north and along the Lao border where signal is less dependable than on the coastal strip between the big cities.

Before you go

  • Riding the northern mountain loops or trekking near Sa Pa, save offline maps first. Coverage there depends on which Vietnamese network your eSIM uses.
  • Zalo is the messaging app many Vietnamese hotels, drivers and guides use. Installing it helps when someone asks to send you a location.
  • Vietnam is commonly paired with Thailand or Cambodia. Overland border crossings are remote, so expect a gap in signal around them.

Is 2G or 3G still running in Vietnam?

2G was shut down on the mainland in October 2024. 3G is still on, with a government deadline of September 2028. A phone that supports eSIM already has 4G, so this affects only old handsets.

Will I have data in remote mountain areas?

Expect gaps. Towns have service, but valleys and passes between them may not. Ask your provider which Vietnamese network the plan uses and check that operator's coverage map for your route.
