Telephone fraud scam where fraudsters make money on inter-operator charges, is becoming more and more popular.

The scammers have gone so far as to pick their phone number, so that it looks like the call is originating from Polish area code, while in fact it is an international prefix. This is, of course, related to the appropriate charge for the connection. A person who will try to call back on such a phone number may be unpleasantly surprised once monthly bill arrives with charges of up tens of PLN.

Recently, the Office of Electronic Communications has warned against fraudster from Africa, such connections, with multiple connections in the Śląskie Voivodeship.

Area code 22 was displayed on the phone screens, which can often be confused with Warsaw. OEC has received multiple complaints regarding calls from unknown numbers with an area code, i.e. +243, +221, +225. Calling back such a number may cost a lot, in particular to premium list numbers with a higher fee.
