I am unable to download MMS messages (whether it be a picture or a group text from an iPhone) after updating my phone to jelly bean. I have a limited data plan, only 150MB, so I keep my data connection off when I am not using it. With ICS this was not an issue. I would simply get a notification that I received a new message and I would turn my data on and click the download button and the MMS would download. When I received the JB update I do the same thing, but the message never downloads. It simply says downloading but never actually downloads the message. My sister has encounter the same issue, so I know it isn't isolated to my phone alone. Has anyone else encountered this issue, and more importantly have a solution?
