Apple is testing a new ‘SOS’ feature that lets you make emergency phone calls, according to Mashable.

On Tuesday, Apple previewed an upcoming iOS app update, which showed off a new “SOS” feature that will let you make emergency phone calls when you press the power button five times.
Once the new feature is enabled, simply press the power button five times to make a call to emergency services.

Apple’s “SOS” feature works in Australia, Belgium, Brazil, Canada, China, France, Hong Kong, India, Italy, Japan, Russia, Spain, UK and the US, according to MacRumors.

To find settings for the “SOS” feature, just go to Settings under the General section.
The “SOS” feature does have a countdown before the emergency call goes through and triggers a siren, which will prevent accidental calls. You can also disable the feature by going to the main Settings app.

While iPhone have had emergency calling available from the lock screen for years now, the new feature lets iPhone owners make a call in case they get into trouble and aren’t able to use the emergency feature from the lock screen.

We’re not sure when Apple’s “SOS” feature will roll out to the public, but for now is available to developers who have the iOS 10.2 Beta2 update installed.
