Why Emergency Contacts Matter So Much

Frequently asked questions

What is Medical ID?
Medical ID is a feature on your iPhone that stores important health information such as allergies, medical conditions, medications, and emergency contacts. This information can be accessed from your iPhone's lock screen by first responders and medical personnel, even if your phone is locked.
How can first responders access my Medical ID?
First responders can access your Medical ID from the lock screen of your iPhone by tapping "Emergency" in the bottom left corner, then tapping "Medical ID." This allows them to quickly see your crucial health information without needing your passcode.
Do my emergency contacts get my location?
Yes, when you use Emergency SOS, your emergency contacts will receive a text message with your current location. If your location changes, they will also receive updates automatically, helping them to find you or coordinate with emergency services.
Can I have more than one emergency contact?
Absolutely! It's highly recommended to add multiple emergency contacts. You can include family members, close friends, or trusted neighbors. Your iPhone allows you to add several people to your emergency contact list, ensuring there's always someone to reach.
What if I accidentally trigger Emergency SOS?
If you accidentally trigger Emergency SOS, don't worry. On most iPhones (like those running iOS 17 or 18), after the countdown, you'll have a brief window to cancel the call to emergency services if you activate it by mistake. However, your emergency contacts might still receive a notification. It's a good idea to text them quickly to let them know it was an accident.
