My husband just upgraded to the LG Nexus 4 . It will not receive MMS messages. Yes, data is on, and can send fine, but cannot receive. I had this problem when I upgraded to the Galaxy Ace, and had to take it in to get Koodo to fix it. They couldn't tell me what they did,so I cannot fix it on his myself.. the APN is correct as to the other questions I have looked at. Help?!
