The cell phone service that you get on cruise ships (roaming). It is ridiculously expensive and costs more than the cruise if you use it. For example, loading a webpage will cost you +$20!
Customer to cell phone provider: WHY AM I BEING CHARGED $50,000 FOR ROAMING?
Customer service: Because you used cellular at sea.
