I hope this helps someone else because as much as I love my note 2, I was ready to run over it with my car. It just randomly stopped receiving or sending MMS with pictures and I thought it was the wifi/data enabled-disabled issue but that didn't work for me because I hardly ever use wifi. So I did a lot of searching and found a fix that worked for me. First let me say I am using goSMS and I would switch back and forth between the native messaging app and goSMS and I had the same issue with both.
The fix I found online suggested going to:
Settings
More settings
Mobile Networks
Access Point Names
once in there you should see something that says ATT Phone, if you have ATT service. Hit the left soft key at the bottom of the phone and click on reset to default. I then did a restart and I was able to send and receive MMS messages. All is well in the world again.
