Can't send or receive photos in text message

[WPCentral Question]

Hi, new member. I have an AT&T branded Lumia 920 that I am using on T-Mobile. Since installing Preview for Developers, I am unable to send and receive pictures in text messages. I am in the DFW area and have LTE coverage. Am I missing something obvious in the settings? Thanks in advance for any help that you can give me.

MMS settings are not proper. I would suggest search forum and see what is correct solution - if access point would work or not.

Are you using Wi-Fi calling or data to get/send them? I originally had trouble with Wi-Fi calling and called and they fixed it.
