‘One-ring’ cell phone scam could cost you money
In a new mobile scam, crooks let the phone ring once — just enough to cause a missed call message to pop up on victims' phones — and then hang up. If you dial the number back you'll find yourself connected to a paid "adult entertainment service" located overseas.
These unlucky victims are generally charged a $19.95 international call fee up front, plus $9 or more per minute for the unwanted "service." (In some cases the scammers charge only a few bucks to the victim's bill to avoid suspicion.)
The BBB said the scam calls usually come from outside the United States, including from numbers with area codes 268, 809, 876, 284 and 473. The practice of third parties placing unauthorized charges on wireless accounts is called “cramming.” The Better Business Bureau recommends if you don’t recognize an out-of-state telephone number on your caller ID, ignore it and if you do answer, do not call back.
If you just can't avoid the temptation to dial that number back, be sure to first pop the digits into Google or a site like whocalled.us They track complaints and questions about calls from specific numbers and you may see what others are reporting. Or check your voicemail - no message, no call back.
