How do I perform pre-arrival activation of my CoreESIM profile prior to landing at LAX or SFO?

Activating your CoreESIM before your flight to LAX or SFO is a streamlined process. Following your online purchase, a QR code will be sent to your registered email address. Access your device's cellular settings (e.g., on iOS, Settings > Cellular > Add eSIM; on Android, Settings > Network & internet > SIMs > Add more) and scan the QR code to install the eSIM profile. Ensure that the 'Data Roaming' option is enabled for your new CoreESIM line. This preparation guarantees immediate data connectivity upon your aircraft's touchdown, leveraging local AT&T or T-Mobile networks.
