Hi, I saw in the previous post that Nation means you will never get charged for roaming, while the Nation Preferred means, you won't get charged as long as you remain within the calling area. So my question is, if you have Cingular Nation Preferred...when would you get charged roaming? I have a TDMA Cingular phone, so if I had Nation Preferred, does that mean in NYC I would be charged roaming? Because in NYC Cingular is only GSM, and the TDMA is AT&T's? I'm just trying to understand when you would be charged roaming fees on the Nation Preferred.
