I'm not sure if your phone will work, but you can leave the ship information with someone back home and in the case of an emergency, the would be able to contact the ship. You can also keep in touch via email.

Your phone won't work when out to sea for sure. It might work in some ports, but I certainly wouldn't count on it. I think you can get emergency contact information from the cruise line to give to your inlaws, and that can be used in an emergency. With any luck, you'll have a great cruise, and they won't have to contact you. Good luck, and happy sailing,

I have Nextel and so far it has worked in 80% of the ports I have been to. I suggest that you call Nextel and inquire about international roaming. It really all depends on the towers and where Nextel contracts to receive signal. Tell them which ports you are visiting and find out what service they have there. You will have roaming charges, but they are far less than ship to shore calls.
