How to Set Up Fall Detection and Emergency SOS

To set up fall detection and Emergency SOS, you generally complete your watch’s health profile, add emergency contacts in the companion phone app (Apple Health, Samsung Health, Google Fit/Personal Safety, or Garmin Connect), then turn on the fall-detection and SOS toggles in the watch settings. According to manufacturer documentation, these features call emergency services and notify your contacts automatically only after the watch confirms you are unresponsive—so accurate setup and a quick test matter. Below is a device-by-device walkthrough plus troubleshooting for the issues users report most.

Before you start: what these features actually do

Fall detection uses the watch’s accelerometer and gyroscope to recognize a hard fall. If you don’t respond to the on-screen prompt within a set time, the watch can place an emergency call and message your contacts with your location. Emergency SOS is the manual version—you trigger it with a button press or hold when you need help. They are independent settings, so enable both for full coverage.

Step 1: Complete your health and emergency profile

The single most-skipped step is the medical/emergency profile. Emergency responders and your contacts rely on this card, and on some watches age determines whether fall detection is auto-enabled.

• Apple: Open the Health app on iPhone → your profile picture → Medical ID. Add date of birth, conditions, and turn on Show When Locked and Share During Emergency Call.
• Samsung / Google: Add emergency info and medical details in Samsung Health or, on Pixel Watch, the Personal Safety app and your Google account safety settings.
• Garmin: In Garmin Connect, open Safety & Tracking to set up your profile.

Step 2: Add emergency contacts

Contacts are what turn a fall or SOS event into a message someone actually receives. Add at least one, ideally two or three.

1. On Apple Watch, add emergency contacts under Medical ID in the Health app; these are notified after an Emergency SOS call ends.
2. On Galaxy Watch, set contacts in Settings → Safety and emergency → Emergency contacts on the paired phone.
3. On Pixel Watch, use the Personal Safety app to add emergency contacts and enable sharing.
4. On Garmin, add Emergency Contacts in Garmin Connect under Safety & Tracking; these receive Incident Detection and Assistance alerts.

Step 3: Turn on fall detection

The exact path differs by brand, but the toggle is usually in the watch’s SOS or safety menu.

• Apple Watch: Watch app → Emergency SOS → Fall Detection, or on the watch Settings → SOS → Fall Detection. Choose Always On or Only during workouts. For users 55 and older it is on by default when age is set.
• Galaxy Watch: Settings → Safety and emergency → Hard fall detection, then select when it’s active.
• Pixel Watch: Settings → Safety & emergency → Fall detection and turn it on.
• Garmin: Enable Incident Detection per activity profile (running, cycling, walking) in Garmin Connect or on the device.

Step 4: Enable and learn Emergency SOS

Set up the manual trigger so you can call for help on demand:

• Apple Watch: Press and hold the side button until the sliders appear, then drag Emergency SOS—or keep holding to auto-dial.
• Galaxy Watch: Set SOS to trigger by pressing the Home/side button multiple times in Safety and emergency.
• Pixel Watch: Enable Emergency SOS and the button-press shortcut in Safety & emergency.
• Garmin: Use the Assistance feature (hold the button) to alert your contacts with your location.

Step 5: Test it (carefully)

Don’t wait for a real emergency to find out something was off. Verify the SOS contact alert and location sharing using your watch’s built-in test or demo flow rather than triggering a live 911 call. If you must place a test call, do it briefly and tell the dispatcher it’s a test.

Troubleshooting common problems

Fall detection isn’t an available option

Confirm your model supports it and that software is current. Older or budget watches may omit the feature. Make sure your age is entered—some watches hide or disable the toggle until a date of birth is set.

Contacts aren’t getting alerts

Re-check that contacts are saved in the phone app (not just on the watch), that the watch has cellular or a paired phone with signal, and that location permissions are enabled. A flaky pairing is a frequent culprit—see these Bluetooth fixes if the watch keeps dropping its connection.

Too many false alarms

If high-impact workouts trigger alerts, switch fall detection to Only during workouts off, or rely on Emergency SOS during sports. You can always dismiss a false alert before the countdown ends.

It works away from my phone, right?

Only on cellular (LTE) models with an active plan, or when connected to Wi-Fi for some functions. Wi-Fi/Bluetooth-only watches need your phone nearby. See our guide on LTE vs. Wi-Fi data plans.

Frequently asked questions

Does fall detection call 911 automatically?

On supported watches, yes—if you don’t respond to the alert within the countdown (typically around 30–60 seconds), the watch places an emergency call and then notifies your contacts with your location, per manufacturer documentation.

Is fall detection accurate?

Manufacturers describe it as reliable for hard falls but acknowledge it can miss some falls and occasionally misfire. It’s a safety net rather than a medical-grade device, similar to how other sensors carry caveats—see our look at smartwatch AFib detection.

Should I turn it on if I’m young and active?

It’s optional. Many active users set fall detection to alert only outside workouts to cut false alarms, while keeping manual Emergency SOS available at all times.

Will it drain my battery?

Continuous sensor monitoring uses some power, though the impact is usually modest. Our battery tips can help offset it.
