SIM Box Fraud Detection

Protecting your revenues

SIM Boxes use local SIM cards to terminate international calls as local on-net/off-net calls bypassing interconnect fees.

Operators can experience significant revenue loss from this fraud. Customers are also affected by unknown callers and no ability to return calls. 

Detect and block SIM Boxes with our end-to-end CLI verification service. Test from virtually any network anywhere in the world with our advanced TCG solution.

  • On-net and off-net SIM identification
  • Instant detection alerts
  • Full pass & fail test report
  • Real subscriber call origination  
  • Competitive & simple pricing
  • Risk-based test methodology
  • No system integration required
  • No network CDRs required
  • Rapid service commencement

Why choose our solution

We perform end-to-end testing from an expansive range of global network routes, which include real subscriber SIM cards, PSTN fixed-line, and VOIP, with CLI verification to detect the presence of SIM Boxes,

Our system can be configured to recognise the operator's number ranges to provide instant alerts on fraudulent SIMs for immediate deactivation.

Real subscriber call origination minimises detection by the fraudsters as SIMs have regular daily usage patterns from end-user devices. Using our large network of crowd testers, we rotate testing to avoid SIMs being whitelisted.

  • Up to 50,000 tests per month
  • Testing from 1 – 12 months
  • Non-connected & connected calls
