I can say for sure that Netflix and Amazon prime work just fine. I don't have an Apple tv subscription, so I can't verify that one.
A:AnswerIn theory you can use your mobile hotspot, however I doubt the speed your hotspot can deliver will be sufficient enough to watch tv without any lag. Maybe you should try seeing if Xfinity has an internet bundle with their new mobile phone plans, might work out for you!
