You Can Ask Siri to Make Emergency Calls
This feature was added to both the iPhone and the Apple Watch. Now you can ask Siri to call your emergency contacts or even 911.
If you want, you can call Siri and ask to call emergency services or something similar, and Siri will display a countdown timer on your Apple Watch, giving you time to cancel the call in case you didn’t mean it.
This feature is automatically enabled, and you don’t have to do anything other than updating your Apple Watch to make it work.
