More than likely sometings in your APN was changed. Was this a phone that was unlocked from another carrier?

Updating your APN settings does not guarantee that MMS (Multimedia/Picture Messaging) will work. MMS is dependent upon your phone model’s limitations. If you have an iPhone and you would like to use MMS, you may need further changes in your iPhone in order to update your MMS settings. You may search online for more information.
Apple iPhone - Internet and MMS (iOS 6 or later)
Go to "Settings," tap "WiFi" and temporarily turn it OFF.
Back in "Settings," scroll down to "Messages" and tap to open it. Make sure "MMS" is OFF.
Go back to "Settings," tap "General" and then "Cellular." Make sure "Enable 3G" is OFF and "Data Roaming" is ON.
Scroll down and tap "Cellular Data Network."
Under "Cellular Data Network," enter the information provided in the table on the left for the APN Settings.
Click on the HOME key to go back to the main phone screen.
Go back to "Settings" one more time, scroll down and tap "Messages" and turn it ON.
Press the HOME key and you are set to send and receive MMS!
Once you have set it up and tested to see it works, you can re-enable "WiFi," turn OFF "Data Roaming" and turn ON "3G" (or leave it OFF if you're not in a 3G area for AT&T devices on our network).

If you go to Settings>General>About>Carrier, what does it say there?

The AT&T carrier file (and 15.0 is the latest one) will override what you have tried to set for APN settings. It has the AT&T settings now. If you can access the APN settings, then change them back to the Straight Talk ones. I'm afraid however, that the updated AT&T carrier file will have closed your ability to access the APN settings.
