I agree there is some stubborn tunnel vision from those falling back on the full diversion to the carrier issue. I was on with Verizon for three hours last night and no luck.
It’s telling is that my iPhone tells me that MMS messaging must be on for me to send photos (when I try to send one) but MMS is turned on. I just don’t know my my phone is confused about that!
I’ve tried everything suggested in this thread plus the troubleshooting last night and I still can’t send MMS pics.
And folks who are pointing to the carrier at all exclusion of potential iPhone issues, go easy. There’s always an outside chance glitches happen within the iOS system. Plenty of anecdotal evidence of that.
