BBM for Android and iOS works on a normal DATA plan which only requires an active internet enabled APN to pass through. But a Blackberry device has its own set of service where it requires service books which can only be pushed if there's an active blackberry BIS / BES service (blackberry.net / bb.net or whatever) to comminucated with other blackberry devices.
This is just the basic to give you an idea on how blackberry works. different service providers provide different DATA plans, but at the backend its the same connectivity between the provider and RIM.

Yes I have many contacts on whatsapp that have a legacy BBM device OS 7.1 but they don't have a data plan because they only use the data over wifi and they are fine in these countries data plans are very expensive.
Now I am migrating all my whatsapp friends from android and iphone to BBM but it is really sad I still have to use whatsapp with people having a legacy Blackberry device with no dedicated BIS or BBM data plans..
Blackberry please issue a BBM version that works over data only ! for legacy devices
