If you are a user of iOS because you or your children have an iPhone, you should make sure that you are familiar with the ways to access the emergency services.
First, you should make sure that you know how to Use Emergency SOS on your iPhone. This lets you quickly call emergency services such as 911.
Next, you should always set up Set Up Emergency Contacts on your phone. You do this through the Health app. Whenever a phone sends an Emergency SOS, it not only calls the emergency service (such as 911), it also automatically sends a text message with the iPhone’s location to the Emergency Contacts. For a limited time, the Emergency Contact will also be updated if your location changes.
Finally, if you have an Apple Watch, you can Send an Emergency SOS on your Apple Watch. In order to make an Emergency SOS call, the Watch needs one of the following:
• To be in proximity to your iPhone
• To be connected to a WiFi network and have WiFi calling set-up
• To be cellularly connected
As with an iPhone, after an Emergency SOS is sent from an Apple Watch, the Watch automatically sends a message to your Emergency Contacts with your location, and will update if your location changes.
