What is International Revenue Share Fraud?
International Revenue Sharing Fraud (IRSF) is the most persistent type of fraud within the telecom industry. Fraudsters often utilize illegal resources to gain access to an operator’s network in order to bring traffic to phone numbers obtained from an International Premium Rate Number provider.
This is the most challenging fraud to eliminate due to the complexity of the mobile network system and the involvement of multiple operators, usually its perpetuated by organized groups using illegal connections to bring a large volume of calls into high cost 'revenue share' service numbers, taking advantage on the roaming capabilities of SIM cards
