Many are those who see a missed call from an unknown number and return the call to find out who it is. However, doing this is a dangerous thing, as some numbers are scams with very high connection rates between lines.

In recent days, the U.S. Federal Communications Commission has warned consumers of a new scam, the Wangiri, in Japanese “one touch and cut. “These calls are likely to attempt to ask consumers to return the call to the number, which often generates per-minute call rates. Users should not return them”, the FCC explained.

Apparently, it is a number that calls, lets just one tone ring and hangs up, with the aim of attracting the victim’s attention and encouraging him/her to return the call to check who is calling. However, when making the connection between the two lines, quite high special rates are applied. As users try to decipher the recording on the other side of the phone, time passes and the bill grows.

The commission explained that the calls were based on the country code 222 of the West African nation of Mauritania, and were reported to be spreading through New York and Arizona, although it is not ruled out that it will spread to more countries. “International revenue-sharing fraud occurs when scammers intentionally direct phone calls to premium rate numbers,” said Tim Prugar, vice president of operations for Next Caller, a real-time verification technology company. “These scammers get a payment from the call. The cost of one of these calls to a consumer “varies widely depending on the location of the number and the amount of time spent on the phone,” he added.

Although calls are taking place abroad, the counterfeit phone number, which is seen on the call recipient, takes the format of a U.S. number: “Advances in technology allow massive numbers of calls to be made in an inexpensive and easy way. In addition, phishing tools make it easier for fraudsters to mask their identity. The agency recommended not returning calls to unknown numbers, especially those that appear to be foreigners. It also suggested blocking international calls and verifying phone company bills.
