Activating your CoreESIM involves a straightforward two-phase process. First, the installation phase: upon purchase, you will receive a QR code via email. Scan this code using your device's settings (typically under 'Cellular' or 'Mobile Data' settings to 'Add eSIM'). This step can be done anywhere with Wi-Fi. Second, the activation phase: once you arrive at your destination country and your device connects to a local network, your CoreESIM data plan will automatically activate, initiating its validity period and providing immediate connectivity.
