Wonder if sms works on a cruise if you go on top deck. $15 one time for 1 month gives you 10 sms + only $0.50 each extra... that's much cheaper than any internet/txt plan that cell phone company or cruise would offer for contacting home from the ship.
The whole point of such things is they work without cell service--the primary purpose is those going into the backcountry.
They do, however, require clear access to the sky--on a cruise ship you would have to be up on deck, not in your cabin. Even tree cover can block them.
