Hi and Welcome to the Community!
There are several carriers named "MTN"...from what I can see, some support the 9320 and others do not. You need to ask your MTN carrier very specifically if their network natively supports the 9320 for HRT, Service Books, and all BB-proprietary functions.
If they say yes, then proceed with 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) Delete and Resend Service Books
3) Batt Pull Reboot
Hopefully that will get things going again for you! If not, then you will need to contact your mobile service provider for further formal support to determine why your BB cannot properly communicate with their network.
