On a cruise about a year ago, the subject of cell phone bills came up at dinner. One of the people there insisted he didn't have to worry because he had Sprint, and his phone used satellites, so he didn't have to pay extra. I tried to tell him that no domestic plan includes cruise ships, but I couldn't convince him, so I gave up. Considering that he had a BlackBerry, I bet his data usage was insane. I just hope his bill wasn't too high.
