On the Spirit in January there were ads on the cabin TV all day long that stated you could use your cell phone anywhere on board now. But my phone, by T-Mobile, never worked from the moment the ship started sailing.
I was really sad too, as I had thought I would have a chance to call my kids, but no.
Five days into the cruise I broke down and made a $21 3-minute phone call from the cabin. But it was worth every penny.
