| # Apple Watch Emergency SOS Feature | |
| Apple watches come in 2 varieties now. 1 is Wifi only and the 2nd is Cellular and Wifi. | |
| The official apple documentation for how Emergency SOS works is here: https://support.apple.com/en-us/HT206983 | |
| Basically the WIFI models need to be near your iPhone or connected to the Internet via Wifi and setup properly. So for it to call 911, the WiFi model must be within 30ft or so of your phone. | |
| The cell versions just work everywhere there is cell signal, and not all of Emergency SOS will work without a plan, the calling 911 part WILL work even if the watch was never connected to a cellular plan. There is a caveat, it can take an extra few minutes(say 5 minutes or less) for the watch to find a cell signal and dial 911 for you when it doesn't have a cell plan. | |
| The cellular version of Apple Watch's emergency services works in many countries regardless of where you bought the watch, so if you vacation in Vanuatu, it will happily call the local version of 911 for you without any extra work on your part. Full list of countries are available here: https://www.apple.com/watchos/feature-availability/#branded-international-emergency. | |
| Apple will auto-call 911 for 2 reasons: Crash detection and Fall detection. Crash detection is basically a vehicle crash. | |
| Fall detection is obviously not 100% accurate, I don't have good data on how reliable it is, but reviews are "mixed". Fall detection will work better when it's on your wrist. It's very likely that the accuracy will continue to improve over time. If you fall and are knocked unconscious, the phone will wait 1 minute before trying to wake you up. Then it will start making louder and louder sounds for 30 seconds(think Fire Alarm type sound). If you still don't acknowledge the watch that you are alive, it will automatically call 911 for you and play a recorded message to 911 letting them know it thinks you are unconscious and where you are (GPS coordinates) When it plays the recorded message, it also plays it locally, so if you happen to wake up or someone wanders by, they will hear the message and people near you can talk with 911 on your behalf without having to do anything. The phone will automatically lessen the volume of the recorded message when it notices someone talking to 911. | |
| If it doesn't notice your need for SOS automatically, then you can manually call emergency services: | |
| * Press and hold your watch's side button (the button below the Digital Crown) until the Emergency SOS slider appears. | |
| * Drag the Emergency SOS slider to start the call immediately. Alternatively, you can keep holding the side button. After a countdown, your watch calls emergency services automatically. | |
| So basically if you push and hold the button long enough, it will do all the right things and call 911 for you. | |
| Battery Life: Depends on the watch and how much you use it, but 24hrs is normal, 48hrs if you put it in low energy mode and otherwise mostly don't use it. The Ultra watches can go through a weekend easily, maybe up to a week. |
