I know you can turn off data roaming. Is there a way to turn off voice roaming as well? I don't think three is anything in settings, but I thought there might be some way to send one of those *### codes to turn it off.
We are going on a cruise to AK and I know that you can get spotty ATT coverage throughout the inside passage. But I also know that the ship has its own antenna and that you get charged a hefty fee if you get on that antenna. It would be nice to just turn off roaming and let the phone search for an ATT signal and pick up messages, etc when it connects.
