Hi and Welcome to the Community!!
MMS (sometimes called "picture messaging") is, on BlackBerry, a component of your data level services...SMS (true text messages) are part of your voice level services.
Hence, 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 contact your mobile service provider (ATT according to your profile here) for formal support...and to be sure that you remain subscribed (from them) to an adequate data plan to enable the services you desire.
