if i were you i would go to network setting an make sure it says GSM only not CDMA/gsm that might be the issue . i had that happen to me once when i first got a blackberry storm.

You say its a Verizon message so my assumption is you should have a Verizon Blackberry service including a BB data plan. It seems the message is telling you they do not recognize the phone as legitimately on their network. the phone does not seem to be unlocked
