Traditional methods/systems like Test Call Generation, Fraud Management Systems and Call-Detail-Records Analysis offer solutions that may look effective in the short run. But they have two key pitfalls in those methods:
- Even though the traditional systems can detect the SIM cards being used by the fraudsters, by the time you block those cards, the fraudster can swap out the SIM cards for new ones in the network. The problem never really gets solved.
- By the time telecom operators detect the fraud in the network, they would have already lost money to the fraudsters.
Any solution to the fraud problem should tackle the root problem and the ability to stay one step ahead of the fraudster. In this case, it is the SIM Box (or/and its many operational buddies like the SIM Server, SIM Gateways, SIM Banks etc.) Fraudsters are becoming increasingly innovative and telecom operators should be able to stay one step ahead of the game.
