Just checked my iPhone 14 Pro Max with 16.1.1 and the "My Location via Satellite" feature in the "Me" area displays with a red "Finish Setup" message. The instruction is to turn on Share My Location in Find My while you still have a network connection.
Apple is going to blow up the satellite system when they activate this, millions of people will be sharing their location and the satellite will have a software crash and they'll have to turn it off and then decide how they want to charge per use. 😵
Well you have to be in an area with no wifi or cell coverage, so not everyone has access to such an area, but yea I was thinking of going for a walk tomorrow and try it.
this is great for adventurers who get into trouble and don't have a cell phone connection. going out on a day hike that turns disastrously bad because of bad preparation or just bad luck and finding out you have no cell coverage will aid greatly in getting help.
