For a problem im having with mms. no matter what they do i cant send out a picture message to anybody. ive swapped iphones because i thought that was the problem. Sim cards and have been on the phone with them for hours each time trying to figure it out. They dont seem to have a fix. Can i cancel my service because im paying for something i cannot use? without the cancelation fee. Jump ship to verizon and keep my 64 gig phone i paid subsidized.
