When it contacts law enforcement, it will play an audio message informing them that you have been in an accident and providing them with your location. (An Apple Watch with Crash Detection can only warn authorities if your iPhone is nearby or linked to a mobile network or Wi-Fi.)

WSJ writer Joanna Stern offers an example of one of the 911 calls made while the owner of an iPhone 14 was tied to a rollercoaster at Cincinnati’s Kings Island amusement park in a tweet. As the automated message plays, muted cries can be heard in the background as the rollercoaster takes its course.
