To achieve immediate data access post-landing at San Francisco International (SFO) or Oakland International (OAK), install your CoreESIM profile pre-departure. Purchase your CoreESIM plan while connected to a reliable network at your origin. Once installed, ensure the eSIM line is enabled and data roaming is activated on your device. Upon deplaning and disabling airplane mode, your device will automatically register with the designated local network, providing instant data access for navigation or ride-share applications.
