Resend your service books - How do I resend my service books? - BlackBerryFAQ

And then do a battery pull - 1st step to take if device is having problems? - BlackBerryFAQ

If those do not work, call your cell carrier and ensure that you have a Blackberry dataplan active on your account and that it is properly set up.
