On Friday, FCC announced consumers with a wave of robococks known as "One Ring" scams – but it has nothing to do with Sauron or his minions in the Middle Earth.
Jokes aside, "One Ring" or "Wangiri" fraud against potential victims with a series of calls – usually from the 222 area code – often in the middle of the night.
"Recent reports indicate that these calls use country number 222 from the West Africa nation in Mauritania," the FCC said in a press release. "News reports have been widespread overnight in New York and Arizona."
It seems like this: the caller (most likely an automated robocaller) dials your number and hangs up almost immediately ̵
That's when the trap has burst; Calling back works like a 1-900 number, and runs up a huge fee, you see on your next phone bill.
Since it is not possible to throw this One Ring in the fires in Mount Doom, the FCC never gives you a call back a phone number you do not recognize. You can also check with your mobile provider to block outgoing calls to international numbers. And unless you know someone in Mauretania, you shouldn't call anyone with a (222) phone number.
