WATCH: Why You Should NEVER Tell Siri The Number "108"
Siri has a feature that people have been using as a prank lately. However, it is a prank that can get you in alot of trouble and possibly endanger others lives. In India '108' is the equivalent to our '911', Apple has included the feaure on iPhones so that no matter where you are, and where you're from you can have Siri call Emergency services.
So by telling her to call 108, she will actually dial 911 in Canada/USA.
So next time someone asks you to say '108' to Siri. Don't.
