Upon disembarking at any Hawaiian airport, navigate to your device's 'Settings' menu, then 'Cellular' or 'Mobile Data'. Select your pre-installed CoreESIM profile and ensure it is enabled for data. Confirm that 'Data Roaming' is toggled ON for the eSIM line; this is crucial for connecting to the local US carrier network. Your device should then automatically register and establish data connectivity, providing immediate access.
