Hidden Phone Farms Fuel Global Scams
23 Apr
Summary
- SIM farms use thousands of phones to automate scam calls.
- These networks are rented to cybercriminals worldwide.
- Governments are acting to ban the possession of SIM farms.
Shadowy SIM farms, vast networks of interconnected mobile phones and modems, are operating globally to facilitate large-scale scamming and phishing operations. These illicit setups are rented to cybercriminals, enabling them to automate spam texting and calling campaigns, impersonating local numbers to gain victim trust. Businesses may use SIM farms legitimately for testing, but their malicious application is a growing concern.
The U.S. Secret Service has identified these operations as potential disruptors of telco services and a means for criminal groups to exchange encrypted messages. One investigation uncovered 94 physical locations with SIM-related hardware across 17 countries, including the US, Europe, and South America. The network was linked to Belarus and Russian-speaking audiences, promoted online with minimal customer checks, suggesting easy access for buyers.
Law enforcement actions are increasing. In September 2025, the US Secret Service dismantled a SIM farm near the UN containing over 100,000 SIM cards, posing a significant security threat with potential for cellular blackouts. In October 2025, Europol shut down a SIM farm linked to over 1,700 cyber fraud cases in Austria and Latvia.
Recognizing the widespread misery caused by scam texts and calls, governments are beginning to act. The UK, for example, intends to ban the possession and supply of SIM farms, providing law enforcement with new tools to disrupt criminal activities targeting the public.
