Off-Net SIM Box Fraud remains a challenge for MNOs worldwide despite successful controls in place for On-Net SIM Box Fraud.
Fraudsters bypass legitimate routes and use VoIP “Grey Routes” to terminate traffic towards GSM Gateways (SIM Boxes) located in the destination network. When SIM Card availability and promotional offers are more attractive for one MNO in a country, fraudsters capitalize on the opportunity to acquire and install SIM Cards from this MNO in their SIM Box. These SIMs can then be used to terminate incoming international traffic towards another (Off-Network) MNO, causing an increase in illegitimate incoming Off-Net (local) traffic towards the victim network.
