BB Data Only plan - voice minutes?

[FutureCrackBerryAbuser]

I'm looking at the BlackBerry® Personal Plan - Data Only.

I hardly ever make calls. In fact, I'd be shocked if I used more than 30 minutes a month. Just in case I do have to make a call though, how much is the per minute charge?

VOICE CALLING: If you have a voice-capable device (unless you request voice blocking, select a data plan that restricts voice access or select a qualified voice plan), the default rate for voice calls on AT&T’s wireless network is $0.40 per minute and $0.69 per minute for domestic roaming voice calls off AT&T’s wireless network. See AT&T Nation map for default voice coverage area.
