iPhone and Apple Watch provide some awesome features when it comes to health and fitness, but they also include important ways to get help in case of an accident, injury, and more. Follow along for how to make sure your Medical ID is set up or up to date, along with how to customize the SOS settings on iPhone and Apple Watch.

Both Medical ID and SOS can be life saving features. Neither one is a shiny feature that is used on a regular basis, which is why it can be easy to not have Medical ID set up, or in the case of SOS, be unsure how to use it.

Medical ID allows users to store important health information along with emergency contact details that first responders can access from the power off screen on iPhone and Apple Watch. As for SOS, there are two ways to activate the emergency feature.

How to set up or update Medical ID on iPhone

  1. Launch the Health app
  2. Tap on Medical ID in the bottom right corner
  3. Tap Edit in the top right corner to enter your information
  4. Make sure the Show When Locked toggle is turned on at the top
  5. Tap Done when finished

Also don’t forget you can add more than one emergency contact, if fact you can add over two dozen. I didn’t find the limit, but I made it to 25.

Apple also offers the option to sign up with the national organ donation registry, Donate Life. This is a simple and quick way to sign up for those interested and travels with users, no matter what state you’re in. Tap the Learn More link just above the button for the fine details.

How to set up or update Medical ID on Apple Watch

The great thing about Medical ID is that it automatically syncs from your iPhone to your connected Apple Watch, no need to do anything. If you update your information in the Health app, it should appear on your Apple Watch almost immediately.

The Health settings in the Apple Watch app are for calculating calorie burn and other health metrics and are separate from your Medical ID profile.

How to access Medical ID on iPhone and Apple Watch

To see what it looks like if someone else would need to pull up your Medical ID, tap Emergency in the bottom right corner of the Lock screen on iPhone. Alternately, on the iPhone X and 8 you can find Medical ID and the SOS slider on the power off screen.

On Apple Watch, press and hold the side button. The Medical ID slider will be available along with the power off and SOS options.

How to customize SOS settings on iPhone

There are three ways to activate the SOS feature on iPhone to call emergency services. Two of the more automatic features are turned on by default in the latest version of iOS 11.

For iPhone X and 8, users can press and hold the side button and either of the volume buttons to start a 5 second countdown (previously a 3 seconds). This is called Auto Call.

The second option is to rapidly press side button (or sleep/wake button), this is called Call with Side Button. The third option is to use the SOS slider on the power off screen.

Here’s how to change these settings:

  1. Open Settings
  2. Swipe down and tap on Emergency SOS
  3. Choose which SOS options you’d like to use by toggling options off/on

Countdown sound

The countdown sound is on by default, which is a loud, alarming tone to make sure you’re using SOS intentionally. You can also turn this feature off if you think you’d rather be able to make an emergency call discreetly.

If you leave the it on the SOS countdown won’t make any sound for 5 and 4, with 3, 2, and 1 all producing the alarming sound.

If you accidentally call 911, press cancel as quick as possible (during my testing and grabbing screenshots for this article I unintentionally placed an SOS call, but as I cancelled it immediately, no emergency services were sent 😅).

How to customize SOS settings on Apple Watch

Apple Watch doesn’t have the rapid clicks of the side button for SOS, instead it features to options. First, users can do an auto SOS call by pressing and holding the side button. Second, you can press and hold the side button until you see the power off screen, then use the SOS slider.

The auto SOS call feature is turned on by default in the Apple Watch app settings.

  1. Open the Apple Watch app
  2. Tap on General → Emergency SOS
  3. Toggle off Hold for Auto Call if desired

Apple Watch features a loud countdown alert sound like iPhone. However, there isn’t an option to turn it off. Even with your iPhone or Apple Watch set to silent/vibrate the countdown alert will sound.

If you feel like getting a little bit of practice in, just to feel more comfortable with the SOS feature on iPhone and Apple Watch just make sure to let go around the 2 second countdown.

Remember, if you accidentally place an SOS call, you should be able to end it before it reaches emergency services if you hit Cancel as quick as possible.
