SIM box fraud
SIM box type fraud is committed through unauthorised use of GSM gateways that the fraudsters use to circumvent the international traffic transfer points, and thereby incur high losses upon telecommunication services providers. The phone calls appear to originate and end in the same network, which enables SIM box providers to offer much cheaper calling rates than network owners, who therefore face unfair competition.
IP theft
According to International Engineering Consortium, IP theft is one of the most common types of fraud in the telecommunications sector. If a fraudster steals an IP from a telecommunications services user, he gains unauthorised access to numerous services. All these services will be charged to the IP owner, who will know nothing of the fraud, until he receives a receipt for services rendered. By that time it is usually too late, as the fraudster will have most likely disappeared into thin air.
