Have you tried a battery pull (soft reboot) with the SIM card you want to use already installed?

I assume that you have a BB data plan (or bolt-on) associated with the SIM. If the battery pull doesn't work, then you may need to reregister using the host routing table and resend your service books.

You must have a BB data plan for email and BBM.
