If someone tells you to say ‘108’ to Siri, they’re tricking you into calling the cops. 108 is India’s version of 911. Because Siri is programmed to make emergency calls, ‘108’ will reroute to your local emergency service. Some online posts even tell you to close your eyes and wait 5 seconds afterwards, because that’s how long you to have to cancel before the iPhone dials and sends EMS to your door instead of to those in need.
