A Study on SIM box or Interconnect Bypass Fraud

Abstract

SIM box or Interconnect Bypass Fraud is one of the fastest emerging frauds in Telecom industry today, costing the industry some USD 3 Billion. Calls made through the internet are sent to SIM boxes (machines that contains SIM cards) which redirect this illegitimate VoIP traffic onto mobile networks. Fraudsters effectively bypass the inter-connect toll charging points to exploit the difference between the high interconnect rates and the low retail price for on-network calls, thus avoiding payment of the official call termination fee of an Operator or MVNO.
