This specific plan is valid only within Laos. Most travelers enter Laos via the Friendship Bridge (Vientiane) from Thailand or by bus from Vietnam. Once you cross the Mekong River or the land border, your previous connection will stop. If you are backpacking across Southeast Asia, we highly recommend our Asia Regional eSIM to keep your data active across Thailand, Laos, Vietnam, and Cambodia without swapping plans.
