On that note - I have AT&T. I'm fine with AT&T, except that group MMS / messaging is broken with non-iPhone users. I've tried calling support, walking into a store, and now - simply given up. I tried two other carriers a few years ago, and had far worse problems, so I just suck it up and call people when we have to communicate. At least that part works.
You sum it up well.
