Overview
SMS fraud refers to the misuse of messaging networks to generate illicit financial gain, deceive end users, or exploit operator infrastructure. It includes schemes such as smishing (SMS phishing), SMS pumping/artificial traffic inflation, grey-route bypass, SIM farm abuse, and unauthorized A2P traffic.

The Challenge
SMS fraud spans brand impersonation, bypass traffic, and high-volume attacks that overwhelm manual monitoring and expose operators to revenue loss, customer harm, and regulatory risk. The CFCA Global Fraud Loss Survey 2025 reports $2.03 billion in SMS phishing losses in 2023 and continues to flag fraudulent calling and SMS as a major industry concern.
Fraudsters impersonate brands to phish users, distribute malware, or drive premium-rate actions.
Bypass tactics (e.g., SIM farms) erode enterprise messaging revenue and compliance controls.
Volume and variability make manual monitoring ineffective.
Customer harm and brand damage increase complaints and regulatory risk.
