DO NOT ANSWER THIS NUMBER! They called three or four times before I picked up. I said 'hello' about 2-3 seconds went by and I got an automated "Goodbye"... but they didn't hang up. I said hello another couple times and my phone went crazy. It started vibrating and when i looked at the screen, various windows/apps were opening and closing. I could not shut off my phone because every time i would push the power button another app would pop up and block the Shut Down button. I do not have a battery that I can pull, so I just started pushing the power button as fast as I can and it luckily went into Airplane mode. When I look at my call log, it dialed EVERYONE in my contacts. When I called some of my family, they said that they got a call from the same number. The only family members that actually got a live person were the ones that DID NOT have a cell. But the live person did not say much of anything. I have no idea what their purpose is, but I do not appreciate that they were able to hack my phone!
