Turning off data roaming is just that. It turns of the data roaming so you can't email, surf the web or use any of the data based features. You have probably been hearing things from people who either don't own an iPhone or don't know what they are talking about. There is a usage counter so if you do turn on the data roaming you can monitor your use but you have to make sure your in one of the 36 countries. I thought the UAE was but I was wrong and I was hit with an extra $100 of data but then again I had had the phone for more than 2 weeks at that point.
