🇻🇳 About eSIMs in Vietnam

Vietnam is deceptively well-connected. Viettel is the country's largest carrier, with Vinaphone and MobiFone alongside it. Some current plans list Vinaphone, and others list Viettel and Vinaphone, so check the plan details if rural reach matters to you. Expect 4G in Hanoi, Ho Chi Minh, Da Nang, Hoi An, and along the Reunification Express train route from north to south.

Travelers here lean hard on Grab (taxis, food, even groceries) and Google Translate for menus, so plan for 8–12 GB per week if you are moving between cities. Motorbike tours through Ha Giang and the coastline south of Da Nang have surprisingly good signal — you can share your live location with family without effort.

Airport SIM kiosks at SGN and HAN are heavily marked up. Set up the eSIM on Wi-Fi according to your plan's start rule, with no cash exchange or paperwork.

How to activate your eSIM in Vietnam

  1. 1
    Time the installation
    Check the selected plan's start rule. If it starts on its first network connection and allows installation before travel, install it over reliable Wi-Fi before you fly; if it starts at installation, install it when you need it.
  2. 2
    Enable on arrival
    After Noi Bai or Tan Son Nhat, switch to the Vietnam eSIM for data and turn on Data Roaming — required for all eSIMs.
  3. 3
    Get Grab
    Grab is essential in Vietnam — taxis, motorbikes, and food delivery all use it. Sign up on Wi-Fi before you go if possible.
  4. 4
    Save offline maps
    Download offline Google Maps for the Ha Giang loop and remote Sapa in case you dip below the border on the higher passes.

Vietnam eSIM FAQ

Which network does Wanderly use in Vietnam?

It depends on the plan. Some current Vietnam plans list Vinaphone, and others list Viettel and Vinaphone. The plan details show the network where one is named, so check them before you buy if it matters to you.

Will it work on the Ha Giang loop?

Expect signal in most towns on the loop and drops on the highest passes. If this route matters, choose a plan that lists Viettel, which has the widest rural coverage.

How much data for a 10-day Vietnam trip?

10–15 GB is comfortable for maps, Grab, translation and social media. Unlimited if you work remotely.

Does it work on Phu Quoc island?

The populated areas of Phu Quoc, including Long Beach and the north, generally have coverage. Signal depends on the network your plan lists.

Can I use it on the sleeper train?

Yes, coverage runs along most of the Reunification Express corridor with brief gaps in mountain tunnels.
