I used my TP1 many many times on cruises. I check my email and sent some photos. Total cost for the trip with 3 mexican port visits was $8-$15 total. Make sure you are on CDMA (because I am sure the GSM partners would be more expensive), call sprint international before you leave to be sure they have enabled your international service, and make sure you are in port and not on the the ships cellphone service.

At sea the ships have a Maritime Roaming service which used to be only voice calls but it now sometimes includes expensive data services. It is supposed to be shut off in port. Normally if you see the roaming signal (the triangle), or it is 1X, you are probably on ship service. Sprint International will be Evdo.
