Success Story

Mobileum Case Study SIM Box 2025

SIM Box Detection in Ucell Uzbekistan

The Challenge:

Ucell Uzbekistan reduced SIM Box bypass from 90% to 10%, but after mid-2017, results stalled as advanced fraudsters quickly detected and avoided test numbers. Manual test number renewal increased team workload and reduced detection effectiveness.

The Solution:

Mobileum recommended and implemented Stealth Mode, a newly designed detection approach that is immune to counter-detection and uses fully automated test number selection. This eliminated the need for manual provisioning and prevented fraudsters from identifying test numbers.

Key Insights:

  • Hidden Fraud Exposure: 

    Bypass detection jumped from 0–3% to 48% immediately

  • Sustained Detection: 

    Ongoing bypass peaks of up to 70% identified

  • Network Protection: 

    Effective against even the most advanced fraud techniques
