If you have watched any number of scary movies or thrillers you’ve come to assume that a cell phone is wholly worthless when you really need it. Either the battery is dead or somehow in the middle of a large city, there is no service. But, in real life, your iPhone can actually save your life if you ever find yourself in an emergency situation. This time, it’s Siri to the rescue.

If you were to find yourself in need of your local emergency services Siri can make the call for you. If your phone is plugged into your car port or charging source, you can use the “Hey Siri” command to activate Siri. This option would be ideal if you were unable to physically reach your phone under your current conditions. People with an Apple Watch can use the watch to activate Siri as well.

Using the “Hey Siri” function or holding down the Home button will activate Siri. Once Siri is on, there are a variation of phrases to reach your local emergency services.

• “Dial 911” The emergency line in the USA. But for all languages and regions that Siri supports, saying “Dial” and the number of your region’s emergency line, Siri will contact the service.
• “Call 911”, “Phone 911”
• “Call Emergency Services”, “Phone Emergency Services”
• “Call the Cops”
• “Call the Police”

Also, if you are an American in Brazil and don’t know the emergency line in that country you can still say “Dial 911” and Siri will take it upon herself to find the correct emergency contact for your current location. Of course for Siri to work, you will need to have access to a cellular network.

Please do not test out these commands needlessly. All of the commands listed above will contact your local emergency service. You will have 5 seconds to cancel the call before their emergency hotlines are contacted. Again, these commands are for emergency situations only. 

Knowing the exact phrases that will prompt Siri to call for help could be clutch if you ever were to need assistance. Just remember, that if you do test this out, to hit Cancel before those five seconds are up. There would be nothing worse than having to explain to the police that you were testing out a command when they arrive at your front door.

It has also been said that saying the command, “Siri, charge my phone to 100 percent” will actually call the emergency line as well. But it seems, that 100 is the emergency number in India so Siri could simply be reacting to that. I tried the command out myself and did have any luck with.

But that would be really cool, if Apple embedded a secret emergency command for spies and hostage situations.

I hope no one really needs these commands, but it’s better to know than not.
