There is the "data plan" for Blackberry phones, and they are "required" on all Blackberries! $29.99 (Blackberry Internet Service) for personal email, browser, chat and it is "unlimited!" You don't have to worry about how long you email, web browse, or chat with Blackberry. The $44.99 (Blackberry Enterprise Server) is when using Blackberry with "work" email, etc. Text, mms is part of a different bundle would pay, not with Blackberry data plan. As for minutes, it would depend what voice plan you have, you pay for voice and the Blackberry data plan.
