Laos, Cambodia and Vietnam sit in one connected strip of Southeast Asia, joined by land borders you can cross overland — travel guides have called this route "Indochina" for a century because it reads as one trip, not three. This eSIM treats it that way too: one profile connects automatically to Unitel in Laos, Metfone in Cambodia and Viettel in Vietnam as you cross each border, on a single 2GB/day data allowance for the length of your plan. No new QR code, no manual network switching, no juggling three separate data balances. It's data-only (no phone number) and hotspot/tethering is supported on all three networks. If your trip stays inside just one of these countries, a single-country plan is the better value — see our Laos eSIM or Vietnam eSIM pages — but the moment your itinerary crosses a border, this is the one plan that follows you.
No. Indochina in the historical sense of French Indochina means Vietnam, Cambodia and Laos — Thailand was never part of it. Our Indochina eSIM covers exactly those three countries: Viettel in Vietnam, Unitel in Laos and Metfone in Cambodia. Some sellers label a plan that includes Thailand as "Indochina", so always check the country list. For Thailand, buy a dedicated plan from our Thailand eSIM page.
One eSIM profile. It connects automatically to Unitel in Laos, Metfone in Cambodia, and Viettel in Vietnam — three networks under one Viettel-group agreement — so you install it once before you fly and it just works as you cross each border, with no new QR code or manual network selection. Turn on data roaming in your phone settings when you land — this is a roaming profile, so your phone treats each network as foreign even though it connects automatically.
2GB of high-speed data per day, for the full length of your plan — 14GB total on 7 days, 30GB on 15 days, 60GB on 30 days. It's a daily allowance rather than one shared pool, so a single heavy-use day (video calls, uploading photos) doesn't eat into the rest of your trip.
No — this is a data-only eSIM, the same as our single-country Laos plans. If you specifically need a real Vietnamese phone number with calls and SMS, our Vietnam Mobifone plans include one, but only for Vietnam.
Yes — hotspot/tethering is supported on all three networks, so you can share the connection with a laptop or a travel companion's phone.
No — if your trip stays inside just Laos or just Vietnam, a single-country plan is cheaper per gigabyte and gives you options this bundle doesn't need to offer, like a real Vietnamese phone number or a longer QR validity window. This plan is built specifically for the multi-country case; get it only if your route actually crosses a border.
A common order is Laos → Cambodia → Vietnam or the reverse — landing in Luang Prabang or Vientiane, crossing south by land or a short flight into Siem Reap for Angkor Wat, then continuing to Phnom Penh or on to Ho Chi Minh City or Hanoi. Install the eSIM before you fly; it stays dormant until it first connects to a network, so there's no cost to having it ready no matter which country you start in.
