Hi and Welcome to the Community!
With a strong carrier network signal (e.g., not merely WiFi), I suggest the following steps, in order, even if they seem redundant to what you have already tried (steps 1 and 2 each should result in a message coming to your BB...please wait for that before proceeding to the next step):
1) Register HRT
2) Resend Service Books
Hopefully that will get things going again for you! If not, then you should contact your mobile service provider for formal support and to ensure that you are subscribed to a data plan from them that is adequate to use the services you desire (many services require a data plan, even if the method of access is only WiFi).
