Nokia Lumia 920 locked AT&T no MMS or group text

[2lalaland]

I tried posting this message several days ago & hasn't shown up in the forums?! So here I go again, I have a locked AT&T Nokia Lumia 920 that won't receive MMS nor group texts. I can send MMS but not receive them. I have been all over the internet & the apn settings for other folks is not working on my phone. Do I need to unlock this phone to work?

My Lumia won't send or receive MMS texts or group messages either! The internet, texting and calls are fine.

I have a Nokia 920 and the MMS worked fine until yesterday when the phone had a windows update and now today nothing. What are the settings for the new update?
