Sorry for resurrecting an old thread, but I didn't want to start a new thread with what is probably a noob question.

If I only subscribe to a plan with BBM & email (no BIS), would I even have to worry about turning data off while roaming? If I don't have BIS, then there is no way the BB will connect to data while roaming, correct? Since BBM uses so little data, I wouldn't mind paying a few dollars for BBM roaming.
