To configure your CoreESIM profile for Barcelona before your flight, first ensure your device is eSIM-compatible and unlocked. Purchase your desired CoreESIM data package, and you will receive a unique QR code or manual activation details. Scan the QR code via your device's cellular settings (e.g., Settings > Cellular/Mobile Data > Add eSIM) while connected to Wi-Fi. The eSIM profile will install, but remain inactive. Upon landing at Barcelona-El Prat Airport (BCN), simply enable the CoreESIM profile in your settings to establish immediate connectivity with a local carrier like Movistar.
