As the thread title says I'm having issues with MMS on the Straight Talk galaxy s3 running on sprint towers. My data is working gloriously, however I'm unable to send/receive picture messages. I am running carbon rom d2lte 4.4.4 the 7/13 build I've tried both hangouts and the default SMS app. If anybody knows anything about this issue or any possible fix pleaseeeee feel free to comment. Any suggestion helps. Straight talk told me to update the profile but i don't have any way of doing that on this rom.
