That missed call on your cellphone could cost you $30…but maybe not in the way you think.
One of my Facebook followers let me know about an old scam that has roared back to life. Years ago, crooks found a way to exploit a handful of international area codes that don't require a foreign code to dial up.
Now that scam has resurfaced as what's being called the "one ring scam." Crooks are using robocalling technology to place Internet calls that only ring once to cell phones.
If you pick up, the robocaller just drops the line. But the bigger danger is if you miss the call. Like so many people, you might think it's an important call and dial that number right back.
