Who’s calling now? That number doesn’t ring a bell. Hold the phone, says the Federal Trade Commission. You could be a potential victim of the growing "one-ring” cell phone scam.

Here’s how it works: Scammers are using auto-dialers to call cell phone numbers across the country. Scammers let the phone ring once — just enough for a missed call message to pop up.

The scammers hope you’ll call back, either because you believe a legitimate call was cut off, or you will be curious about who called. If you do, chances are you’ll hear something like, “Hello. You’ve reached the operator, please hold.” All the while, you’re getting slammed with some hefty charges — a per-minute charge on top of an international rate. The calls are from phone numbers with three-digit area codes that look like they’re from inside the U.S., but actually are associated with international phone numbers — often in the Caribbean. The area codes include: 268, 284, 473, 664, 649, 767, 809, 829, 849 and 876.

If you get a call like this, don’t pick it up and don’t call the number back. There’s no danger in getting the call: the danger is in calling back and racking up a whopping bill.

If you're tempted to call back, do yourself a favor and check the number through online directories first. They can tell you where the phone number is registered.

If you’ve been a victim of the “one-ring” scam, try to resolve the charges with your cell phone carrier. If that doesn’t work, file a complaint with the Federal Trade Commission and the Federal Communications Commission.

And as a general rule: Read your phone bill often — line by line. If you don’t recognize or understand a charge, contact your carrier.

I’ve got to go now; my cell phone is ringing.

It's probably similar to a 900 number. But they don't need to ask for a credit card since they can just bill your cell phone provider. And possibly because it's a foreign service, they aren't required to get your permission before they start charging you.

I got a call from +1(597) 0 unfortunately I was caught of guard. The moment I answered and saw the number I told them never to call this number again. They hung up, the person didn't speak very good English.

Received a call showing on my cell phone as +1 (1) (575) 066-420. I did not answer it and put the number in google to look it up and was taken to this site. I almost called back since we do business out of the country and employees are currently traveling. I will block it but I am sure will get more from other numbers. I wish there was something to do to prevent this.

I jus thought got a +232 call saying from Sierra Leone and did not answer. However, when I went to see what the number was to Google, it accidentally dialed it back. I hung up immediately but it shows 10 seconds....I hope I don't get dinged with a charge. Wish to goodness there was a way to stop all this mess.

I got called by +257 78 13 18 28 i was gonna open it untill it hanged up then i searched it up i said “Thank God i didn’t answer the call!” Because it is a scammer! So please don’t answer it it takes money away unless you have free international minutes which is very rare but still if you do have them don’t answer them.

I keep getting these one ring calls at 2 and 3 in the morning. Your heart stops when the phone rings in the middle of the night like that cause no one calls just to "Chat" at the time, it's always something bad. But this call is from France, 33-825-93-71-66. I don't call back cause I don't know anyone in France and if I did they would know better than to call in the middle of the night and would leave a message. So Annoyed!!

I thought this article said they targeted cell phones. I am getting called on my land line. So I guess people should be aware regardless which device these calls are being made to. Technology is great but sometimes it just adds more problems.
