My cousin used hers to talk to her daughter while on our cruise. The daughter was staying with her dad (cousins ex) and we were amazed at how long she talked, since we were in Mexico. We could not convince her that her cell bill would be outrageous. She kept saying that her bill would be fine, it would be her ex's that would be high. Never heard how that turned out, but I don't think she ever used her phone on a cruise again! My husband does have to keep his on, but the company pays his bill. They are the only ones that ever call him when we are on vacation - and they insist he keep it on. Don't know why no one else can solve any of the problems - but as long as they pay the bill, it doesn't bother me . At least not too much!
