I'll leave aside the meta commentary on your (unneccessary) downvote comment.
Facetime is what makes it possible for me to stay in touch with my family on the other side of the planet, and that's even if I'm sitting out in a park far from Wifi. It just works, and even if it hiccups once in a while, the reliability is high enough that you just shrug it off with the confidence that it will recover. This is on LTE with good reception.
