Roaming and wholesale fraud can generate significant losses within hours, often before delayed data and manual reviews reveal the activity. The CFCA Global Fraud Loss Survey 2025 cites $3.82 billion in wholesale fraud-arbitrage losses in its six-year comparison, while earlier surveys reported $2.33 billion in wholesale fraud losses.

Overview​

Roaming fraud can include SIM cloning, unauthorized usage, and rapid spend escalation while a subscriber is roaming. Subex helps CSPs detect unusual roaming behavior early using roaming feeds and behavioral signals, enabling targeted interventions before exposure grows.

The Challenge

Roaming and wholesale-related exposures often show up as arbitrage and wholesale fraud–arbitrage is shown at $3.82B in the six-year comparison, and wholesale fraud has been reported at $2.33B in prior surveys. (Source: CFCA Global Fraud Loss Survey 2025).

Roaming usage can ramp quickly, creating high-loss events within hours.
