I have the solution for you
First don't even bother about resetting app or clearing cache. This would make your lfe miseraable so follow.
As far as your messaging app is concerned it is working perfectly fine as it was unable to download mms from server.
These occur due to changes in APN settings. to go to APN settings Settings-->more-->Mobile networks-->Access point names.
I suggest you call AT&T customer care from another mobile as you need this one to edit the APN fields. Ask them for APN settings as you were unable to get mms but you can access data.
OR, you can search how to set apn settings for ATT by google search and results will popup.
After you change all fileds in APN, don't forget to Save. This is the part where everyone makes mistake.
Now, restart the phone and check now wheather MMS downloads or try to send one to your friend.

Did you ever get your problem resolved and how?? I am having the SAME exact problems and cannot find any solution. I've tried everything.
@userON5MncDfUJ Have you tried wiping the cache partition on your device? Have you tried resetting the network settings? Just a heads up, by resetting the network settings, it will remove all wi-fi and Bluetooth settings you currently have saved.
