Except then this thing were they assign you to a single cell and the vessel may pass the boundaries of said cell? Do you expect some sort of protocol for automatic handoff to the next cell in the future?
The limitation with the cells is that currently not all cells have the same amount of sats above them so they will not claim that guarantee anything.
Some people have tested that and it worked fine if you move it.
They will likely have a different terminal or plan for mobile service, would be my assumption.
