Affirmative. CoreESIM advises pre-installation of your Hawaii eSIM profile before your flight to either HNL or OGG. Upon purchase, you will receive a QR code or manual configuration details. Integrate this profile into your device's cellular settings. The eSIM will activate and connect to a local network (e.g., AT&T, T-Mobile) automatically or upon manual selection once your device detects network availability in Hawaii.
