Anyone else have problems with using the iPhone and AT&T MMS?
I am the "main" line on a family plan, with unlimited texting. All the other lines (all iPhones) can use MMS no problem. When I try to send a picture, it often gets the red exclamation point indicating a send failure.
Sometimes, if I reset network settings, I can then send a picture, but usually within a week or so afterwards I start getting the same problems.
I have called and they have "fixed it" (who knows that they do on their end) but then the problem usually reappears one to two weeks after the fix.
I am getting very frustrated with this!
