If you have to ask, then you don't fully understand, do you? ;)
The Blackberry device needs to authenticate to RIM's network/servers in order for data transfer to be possible. You need a BB Data plan to allow this authentication.
Non-Blackberry devices don't care about RIM's servers. They use the carriers data network.
