Once your plane lands at HNL or any Hawaiian airport, simply go to your phone's settings, navigate to 'Cellular' or 'Mobile Data,' and select your Cellesim eSIM profile. Ensure 'Data Roaming' is enabled for the eSIM (though it's not roaming if it's a local US plan). Your device should then connect to a local 5G/4G network, providing instant data.
