A Plethoric Literature Survey on SIMBox Fraud Detection in Telecommunication Industry

Abstract

SIMBox or Interconnect Bypass Fraud is one of the most rapidly emerging frauds in today’s telecommunications industry, costing the industry between $3 and $7 billion USD in annual revenue losses. This was spread as a result of calls made over the internet and routed to SIMboxes (machines that contain SIM cards) that redirect illegitimate VoIP traffic onto mobile networks. Fraudsters effectively avoid the inter-connect toll charging points by exploiting the difference between the high interconnect rates and the low retail price for on-network calls, thereby avoiding payment of an Operator’s or MVNO’s official call termination fee. This paper is a fact-finding type that investigates the impact of SIMBox fraud on the telecom industry and the economic development of nations. By disclosing the fraud detection approaches used for its abolition and identifying their flaws. For this study, a quantitative method was used. The study’s literary material spans the years 1994 to 2021. Journals, white papers, M.Sc., and Ph.D. theses on the subject are examples.
