What WILL possibly work on the ship is WiFi, but there may be a charge the ship imposes to use their WiFi capabilities and may be quite significant. Have you checked with your cruise line/travel agent to determine what is providee. They would more likely be able to provide this kind of information, especially since we have no idea what cruise line you are using.
This depends on where your cruise is going. It will work if you go somewhere that VZW service is provided (such as Puerto Rico), but otherwise you will need a global device. As mentioned, it's possible that you can have wifi access on the boat but you need to check with the cruise line to see what is offered and any cost associated with it.
I've heard that a few cruise ships companies work with a few wireless companies and provide signal for you while youre on the ship at no extra charge, if not, use wifi on the ship, it probably has it since were in a world that no internet means no life, get a free app called talkatone and it allows you to use your google voice to make free calls over wifi or 3G.
I understand you may be enjoying your cruise by now; however, I'd like to provide a link for you and all members that have replied to you as it may benefit anyone planning a trip in the future.
