I was just reading a post about the ferry to spain and remembered about this, so a reminder/information :-
Make sure you turn your mobile data OFF on the ferry, and only use the free wi-fi, which is available in parts of the ship.
If you leave your data on it will likely access the internet through the on-board satellite system, which will present you with a big bill. I know loads of people that have been caught out going across the Bay of Biscay. The same goes for making telephone calls whilst on board the ferry.
Text copied from a post by #Mikebeaches in 2019, I assume the situation is still the same.
