I am going on a cruise with my husband on Monday and last year he made me take the battery out my phone and everything cause we were afraid we'd get charged crazy fees for using it out of the country. We have the package with unlimited data and like 1500 minutes. We are just going to keywest (a little island outside of florida) and cozumel mexico. does anyone know about charges for this stuff or if their even is any charges? ive never been charged for roaming or anything...
