I wanted to bump this thread to see if anyone else has had any experience using their mobile phones on board.. Kathy, were you ever charged for roaming? What if someone called but you didn't answer?
I have an unlocked GSM phone with an international SIM (free incoming calls in Europe, 30-60cents per minute calling back to US). I don't want to end up using the ship's signal if I can get a cheap signal from shore or while in port.
