I bought a locked to T-Mobile 8220, and successfully unlocked it to ATT...but as with any other locked phone after unlocking I can't send or receive MMS messages. I spent over an hour on the phone with ATT she tried everything to try to help me and then sent me to an ATT blackberry expert only to have them tell me because it was a locked phone that they couldn't help me. I've tried just about everything with no success! Please help!!

Do you have a BlackBerry Data Plan on your account?

[luvdarts14]

No, I had an unlocked blackberry 8110 previously and had no problem sending or receiving without the plan.

You need to upgrade your software, thats what even t-mobile says to their customers

I had same problem with .180 and since i move to .222 everything is fine.

I have an unlocked 8220 on AT&T and have not had any problems with MMS. I did upgrade to the .278 right when I got it
