To what carrier is the device branded?
On what carrier are you trying to use it?
Do you have an active BlackBerry Data Plan?

Sounds like you do not have the right type of plan for the blackberry. Most things wont work without one. The SIM may only have a standard cell data plan. The carrier can tell you.

If the device is branded to a different carrier than the one on which you are trying to use it, then you need to make sure that the device is unlocked.

BlackBerry Messenger requires a BlackBerry Data service from the service provider.
