Hi and Welcome to the Community!!
Unlike SMS (which is tied strictly to your voice-level services), MMS is a service tied to your data level services. Consequently, 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
3) Batt Pull Reboot
Hopefully that will get things going again for you! If not, then you need to work with your mobile service provider for formal support...they are responsible for delivering all services for which you pay to your BB. If you are subscribed to, from them, an adequate data plan to enable MMS, then they are responsible for delivering it to you...after all, you pay them for your services. They have the power to escalate your case up to BlackBerry for enhanced support if needed...but no one here can do that...only your carrier.
