iPhones have had iMessage over satellite since I think the 15? I've used it when camping. It's pretty neat!

Features I want: ask siri for the things I look up and it works. "When did the baby fall asleep" instead of opening Nanit. "How many more intervals in this workout" instead of opening TrainerRoad. "What is my next meeting" instead of opening Outlook. This was the promise of the new Siri and it just has yet to really come true.
