Just signed up for the $20 ATT unlimited last night on a 7th gen iPad for my daughter. im still using the grandfathered unlimited from 10 years ago. I’m headed out for an 8 hour drive tomorrow. I’ll let you know the streaming differences after I put it to the test. My daughter can burn some serious data on kids YouTube. My whole family has some form of ATT unlimited on our iPhones and iPads. My son has an older (about two years old) ATT unlimited and there’s for sure a video streaming difference between his and mine. I don’t know the lingo but I’ve witnessed it first hand.
