Vietnam is a long, thrilling country, and you'll probably see more than one end of it. A ride-hailing motorbike through Saigon traffic, lanterns in Hoi An's old town, a boat out on Ha Long Bay, a sleeper train north to Hanoi: you'll book, navigate and translate almost all of it on your phone. A travel eSIM gives you local-network data from the arrivals hall, with no SIM stand haggling and no swapping out your home SIM.
Why an eSIM makes sense here
Your home SIM is the one your bank sends its codes to, and you'll want it safely in your phone, not in a little plastic bag. With an eSIM you install at home on Wi-Fi, keep your own SIM for calls, and switch your mobile data to the travel line when you land.
It also means the ride-hailing app works the second you step outside, which in Saigon's heat and traffic is worth a lot.
Whose network you're on
Our Vietnam plans can use Viettel Mobile, Vinaphone and MobiFone, the country's big three operators. Coverage is strongest in the cities and tourist centres: Ho Chi Minh City, Hanoi, Da Nang, Hoi An, Nha Trang. Out among the rice terraces of Sapa or on a remote stretch of the Ha Giang loop, expect the signal to fade in and out.
How much data does a Vietnam trip need?
Two weeks of maps, rides, messages, menu translations and a few stories fits in 3GB; our 3GB plan for 15 days is $5.5. Vietnam's cafés almost all have Wi-Fi, which helps stretch it further.
Travelling the whole country over a month, working from a Da Nang beach café, or posting video every day? 10GB for 30 days is $17 and lets you forget about the counter.
Landing checklist (60 seconds)
Turn the travel line on, set Mobile Data to it, and switch Data Roaming off on your home SIM. Open your ride-hailing app, drop a pin on your hotel, and let the city sweep you in.

Quick answers
Does a Vietnam eSIM give me a Vietnamese phone number?
No. It's a data-only plan, with no local number and no calls. Keep your home SIM active for calls and use messaging apps over the eSIM data.
When does the plan start counting?
When the eSIM first connects to a network in Vietnam, not when you buy it. Install it before you fly, on Wi-Fi.
Is the data unlimited?
No. Every plan has a fixed amount of data for a fixed number of days. Pick a bigger plan if you'll stream or post a lot of video.
Will it work on a side trip to Cambodia?
This plan is sold for Vietnam. Coverage in other countries is not included unless the plan says so.
