Hi and Welcome to the Community!
Any BB can be used on any carrier that runs the same radio frequencies that the BB is capable of (and I've no idea if your's are such). But, to bring a BB onto a carrier network that they did not sell to you, there are several hurdles to cross:
1) The carrier must say "yes" to the fact...they own their network and have every right to say what devices will be allowed to connect to it. If they say "no", then that's the end of it.
2) You must be sure that your BB is properly unlocked from it's originally manufactured-for carrier...see this helpful thread for details:

3) You must get all of your voice level services functioning on the carrier, before you even try anything about data...further, if your BB PIN remains registered with any carrier BIS system, no other carrier will be able to create a BIS account for it. But, if you leave the other carrier BIS account active, it is possible (not guaranteed!) that your BB could receive BIS services from your original carrier while SIM-connected to a different carrier.
4) You must subscribe, from the carrier, to an adequate data plan to enable the BB-proprietary services you desire
5a) If the carrier directly supports your specific model BB, then you can proceed with registering the BB onto their network, generating the proper Service Book delivery to your BB, and proceeding to function.
5b) But, if the carrier does not directly support your specific model number of BB, then the challenges are much greater as most carrier systems will not deliver, to the BB, the necessary service books to enable the BB-proprietary data services, even if you do subscribe to them.
So, depending on all of that, your BB may or may not ever fully function on that carrier network. It can be quite tricky to accomplish, especially if 5b applies. So take a look at all of that and decide how you wish to proceed. Most folks wind up just buying a new BB if 5b applies.
Good luck and let us know!
