Cannot MMS, HELP!

[wavezero]

Having massive problems with my MMS. Can not receive any texted media, nor send.

Whenever I try to send a picture text I get the error under Notifications "Unable to send Message after m..." (cannot read the rest). Then under that it reads "Service denied."

I have scoured many forms and spend an hour or so with google to no avail. It seems like most other people with MMS problems are network related and throw a different error message.

I rooted my phone the first day I got it, and the mms has never worked.

Am I the ONLY one who has had this problem?
