I have the B2B plan with 1500 messages for $8.99. I was able to successfully send a single MMS yesterday, but all other attempts have failed (red "!"). I also had my brother (on Verizon) send me a picture, and all I got was the message telling me to log into the website to see the picture message.
My AT&T account lists my plan as "Text Msging 1500 B2B: 1500 Text Messages" so I'm not feeling too great about being able to keep this plan AND get MMS working.
