Just got the update on my iphone 14 for sat sos. They have a nice little demo where you can try it out.
Seemed to be pretty quick. found a satellite in about 15-20 sec. and was able to send and receive a test message in about the same amount of time.
It started out having me point due east and then flipped me around NW to find a new sat. This could be a problem if you were badly injured and couldn’t move or hold steady enough to get a good connection.. compared to a standalone device where you could just press 1 button.
If you have a 14 and want to try it, you go to Settings>Emergency SOS>scroll to bottom> Try Demo
