eSIM data plans for Vietnam

Vietnam is covered here through two distinct plan types: fixed data allowances on Vinaphone's 4G and 5G network, and day-by-day unlimited plans on Viettel's 3G and 4G network. Which one suits you depends less on how long you're staying and more on how you use your phone once you're there.

Fixed data or unlimited

A short trip with light use, checking maps, messaging, sharing a few photos, fits comfortably into one of the smaller gigabyte allowances, from 1GB over a week up to 5GB across a month. Longer stays or heavier use, streaming, video calls, constant navigation, sit better with an unlimited plan sold by the day, from a single day up to 30.

Before you land

The validity window on any plan starts at first connection to a network in Vietnam, not at purchase and not at install. Installing your eSIM before you fly costs nothing: there's no clock running while you're still packing.

Topping up a fixed data plan

The fixed-data plans stop once the allowance is used, and a top-up on the same eSIM brings the plan back without a new install. Anyone unsure how much data a trip will need can start with a smaller size and add more later rather than guessing high from the outset.

How the unlimited plans work

The unlimited day plans carry a fair use policy: once a day's usage passes a set amount, speed for that day is reduced. They're priced by day count rather than by data volume, which suits anyone who'd rather not track a gigabyte total during the trip.

Sharing the connection

Every plan here, fixed data or unlimited, allows hotspot and tethering, so a single eSIM can share its connection with a laptop or another device.
