re: ATT Unlimited Plan + Directv Now

If AT&T works like Verizon you aren't automatically slowed after 22GB. You may be deprioritized while you're on a congested network. Odds are you won't notice a slow down at all. I'm at 35GB with Verizon and have had videos get a bit grainy for a minute or two a few times but that's it. Check and see if the unlimited plan is throttled or deprioritized. They aren't the same.
