Not cheap. 50 cents per minute is the base charge as I recall, although there are packages of various numbers of minutes that are cheaper. RCI had an unlimited internet for $100 but ended it - at least on the Freedom - prior to it's first revenue voyage last June. But I have read where it is still available on other RCI ships. Indeed, they may have it back on the Freedom by now but I don't know. I figured they stopped it before the inaugural voyage just to avoid the internet access being overwhelmed and crashing - not a good thing to happen on a first voyage with paying passengers.
