I'm not sure if this is the right place to ask this but I have an unlocked Lumia 930 and I just got the Denim upgrade installed over this past weekend. The upgrade has some nice features to it BUT since the upgrade I have lost the ability to send and receive picture messages (MMS). Regular text msgs still work. I've Googled a lot of different solutions with APN and MMS settings but none have worked. Can anyone help me with fixing this?
