The iPhone has an option to tell it to ignore any particular wifi signal so I blocked out the ship's wifi and was then able to use my phone both as a phone and as a wifi hotspot.
I assume you were doing this while in port or just offshore. Otherwise, your hotspot would be running off the ship’s $2.99/ min cell service.
