Before you fly or at your destination: Step-by-step installation

Important Notes:

To install an eSIM, ensure that you have an eSIM compatible and network-unlocked device.
For successful installation, you MUST have a stable Wi-Fi connection when activating an eSIM.
Installing your eSIM before you travel will not affect its data usage and validity; with exceptions (see list at the end). Your eSIM will only be activated upon arrival at your destination, and the validity begins once you are connected to the local carrier. If the eSIM covers more than one country, it will activate at any of the covered countries (eSIMs that activate at the time of installation: Ubigi and Dtac)
