Fraud and revenue leakage cost mobile operators billions every year, eroding margins across data, messaging, and voice. It’s rarely one dramatic event, more a steady erosion in two directions at once: cash paid out on fraudulent traffic, and revenue never collected on services already delivered.

To help MNOs detect and counter fraud and revenue leakage, we have published a new handbook, breaking down the biggest threats in each domain:

• Data: Charging bypass, and how encrypted traffic is exploited to access data for free.
• Messaging: Grey routes and SIM banks, and how they divert A2P revenue from authorised billing paths.
• Voice: International Revenue Share Fraud, and how it generates costly traffic operators are left to settle.

The handbook covers the specific techniques fraudsters use and why they’re so hard to catch. It also discusses how enforcement based on visibility and real-time intelligence closes the gaps, helping operators secure, optimize, and monetize their networks. Read it to start plugging the leaks.
