Getting online across Vietnam
In Vietnam the plan uses Viettel, Vinaphone and MobiFone, the country's big operators. Coverage is usually good in Hanoi, Ho Chi Minh City, Da Nang and Hoi An. In mountain areas such as Sa Pa and Ha Giang, and on a cruise around Ha Long Bay, the signal can weaken or drop.
Data is used constantly. Grab covers taxis, scooter rides and food orders, Google Maps handles routes and a translator helps with menus. Vietnamese people message a lot on Zalo, but WhatsApp and Messenger also work with most hosts and tour operators.
A local SIM card is available at the airport, but registering it needs your passport and time, and queues can be long when many tourists arrive at once. The eSIM is installed in advance and your own SIM stays alongside. Traffic is busy and street names are hard to say, so a Grab ride with the address already pinned on the map saves explaining and haggling over the price.

Less reliably than in the cities. On a bay cruise or on mountain roads the signal varies, so download maps and tickets for offline use.
