Combating Fraud in Telecom: Roaming & SIM Swap Detection
Fraud remains one of the biggest threats to telecom operators worldwide, costing the industry an estimated $38 billion annually (CFCA). Among the most damaging types are roaming fraud and SIM swap fraud, both of which exploit system gaps to steal revenue and compromise customers.
With growing adoption of digital wallets, mobile banking, and IoT devices, the stakes are higher than ever. Fraud doesn’t just hurt revenue it destroys customer trust.
Understanding the Fraud Landscape
Roaming Fraud
Occurs when fraudsters exploit international roaming systems, often by using stolen SIM cards or exploiting billing lags. Losses can escalate rapidly because usage charges may take hours or days to reconcile across operators.
SIM Swap Fraud
Fraudsters trick telecom providers into activating a new SIM for a customer’s number, gaining access to calls, messages, and most critically one-time passwords (OTPs) used for banking and authentication. Victims often realize only after financial damage has occurred.
Why Traditional Methods Fall Short
- Rule-based fraud systems fail to detect evolving fraud patterns.
- Delayed reconciliation allows fraudsters to exploit time gaps.
- Manual investigation slows down response, leading to financial and reputational damage.
AI-Driven Fraud Prevention
AI brings real-time intelligence and predictive defense to telecom fraud management. By analyzing behavior patterns and anomalies across millions of transactions, AI identifies fraud attempts within seconds.
Key Capabilities:
- Roaming fraud detection: AI agents analyze cross-operator usage in real time, flagging abnormal activity (e.g., sudden high-volume calls from unusual geographies).
- SIM swap prevention: AI correlates unusual account changes (e.g., SIM replacement requests combined with password reset attempts) to flag high-risk activity.
- Behavioral analytics: AI learns customer usage behavior and spots deviations instantly.
- Cross-system monitoring: Intelligent automation reconciles activity across billing, CRM, and network logs.
- Autonomous fraud response: Agentic AI can automatically block suspicious SIMs, alert customers, and trigger fraud investigations.
The Business Impact
AI-driven fraud detection helps telecom providers:
- Reduce fraud losses by up to 60%
- Protect customer accounts from SIM-based financial theft
- Strengthen regulatory compliance and reduce liability
- Safeguard brand trust by ensuring secure mobile experiences
- Enable real-time fraud response instead of reactive measures
At Amantra, we empower telecoms with Agentic AI systems that don’t just detect fraud but actively prevent it. By combining anomaly detection, behavioral intelligence, and autonomous response, we help operators stay one step ahead of fraudsters—protecting both revenue and customer trust.
