No, eSIM data bundles purchased for Laos are only valid within the country. You’ll need a new plan for other destinations. If your next destination is Vietnam, Myanmar, or China, consider purchasing multi-country plans that allow usage across locations with better value.
Install the eSIM with a QR code sent to your email. You can follow the instructions attached in the email. Contact us if you need more information. Read full detailed installation guides.
As you need Wi-FI to install your eSIM and your eSIM will not start until you reach Laos and dial 121 to activate it, we recommend that you install your eSIM before departure and dial 121 to activate it when you reach Laos.
You can dial #101# or #122# to check your phone number and balance.

The QR code can be scanned once which means that if you remove the eSIM from your phone, you cannot install it again. And eSIM can only be installed on one device.
