LPT: iPhones have an SOS feature that alerts your emergency contacts and emergency services

I like this because it can be activated via clicking buttons repeatedly or by Siri. So if your phone is even nearby it can be activated via Siri or done silently in your pocket if you want to do it without others knowing or if you can’t speak. There are several options and functions with this feature so look into it and learn how it works before you are ready to use.
