KEY BISCANE, Fla. - Three boaters can thank Apple’s Siri for saving their lives.

The fishermen ran into rough seas about four miles off the coast of Key Biscayne Saturday morning.

The waves were too much for their 18-ft. boat, so it began taking on water.

The boaters were able to put on life jackets before the boat sank.

Police said one of the boaters couldn’t use his phone’s screen to call 911, so he turned to Siri for help.

“They had an iPhone 7, which I'm learning today is waterproof. However, he couldn't touch the screen with his fingers because they were cold, but he used Siri to call 911," said Sgt. James Barrett.

A coast guard chopper eventually found the boaters, and dropped in a diver until the Miami-Dade Police arrived.
