Could you let the rest of us experiencing this issue know if Sprint will be resolving? Bottom line, MMS while connected to wifi used to work now it does not.
I'd like to get you on to our Tech Support Department so they can further look into this. Please send us a Private Message with your contact information so we can get you connected to them.
I just got off with Sprint and this worked. I have a S8 plus..
Try going to:
Reset network settings
Follow all of that...
My internet on data didn't work after that so I had to do this,
Hope that helps you all
i have been MIA for a bit...but which phone was this on again?
