Unauthorized reloading of prepaid SIM cards by employees who have access to prepaid reload/top up systems.

Any activity by a dealer or contractor that deprives a mobile operator of revenue. In many cases, it is an employee trying to increase his/her commission payments.

Using fraudulently obtained subscriptions on another mobile operators’ network with no intention to pay and to exploit the time frames required for the home network to gain visibility of the fraudulent activity.

Abusive use of telecommunications products and services through by artificially generating, stimulating, or prolonging the duration of voice, data or SMS traffic with the intent of obtaining money from customers and/or their communications service providers

Using a gateway switch (sometimes called “SIM Box”) to terminate calls to a mobile network, as if they were calls from that same mobile network. This scenario bypasses interconnection agreements between the mobile network and legitimate fixed networks, resulting in interconnect fees not being paid to mobile operators. The traffic is billed as on-network calls instead of interconnect national or international calls, with operators receiving only the value of the “on net calls”. In Asia, interconnect abuse using GSM gateways has also been referred to as “International simple resale”.

Illegal use of SIM cards and SIM Boxes to terminate international calls, which bypass legitimate routes. Fraudsters divert international calls and text messages through lower-cost routes, which permits them to increase their profits by paying lower charges to the next operator in the call chain.

Exploitation of network and protocol misconfigurations that avoid triggering credit control requests to the intelligent network (IN) element, therefore allowing prepaid customer traffic to proceed without checking of balance, time/volume limits or deduction of funds. Similar exploits can also exist to bypass off-line charging for postpaid traffic.

Short calls or fake missed calls with the purpose of leaving a missed call notification that prompts a victim to call an international premium rate number. Originating from Japan, “Wangiri” means “one ring and cut”.

Any activity by an employee or contractor, which deprives the mobile network operator of revenue or property or obtains financial or special advantage through unauthorized or unlawful activity.
