What he is talking about is the data package your on. You do have one right? What you will have to do is options>advanced options>host routing table. Send new registration. When you get the conformation return, then wait a few minutes, and go into your email settings and re-send your service books. That should get you squared away. But call tmob and see if your account is set up properly to a BIS account first, that will save you headaches.
I do have the data package and I have not had any problems with this until 151.
I did reregister and resend my service books though
