Unlocked HTC 8X (TMobile) cannot send/receive MMS on AT&T

[Papias]

I have HTC 8X (TMobile) and unlocked it to use it on AT&T. Everything works fine, but I am unable to send/receive picture texts (MMS). I've tried some of the suggestions in online, but no go. Can any one help me? Thanks in advance.
