Stop SIM Box Scams Act

Introduced October 1, 2026

AI-Generated Summary

Updated October 7, 2026 at 4:22 AM UTC

The Stop SIM Box Scams Act adds a new prohibition to the Communications Act that makes it illegal to manufacture, import, sell, lease, advertise, possess, use, or modify any device that functions as a "SIM box." A SIM box is defined as equipment that pools multiple SIM credentials to hide the origin of calls or data and evade carrier controls. The law directs the FCC to issue rules, coordinate enforcement with other agencies, and allows mobile carriers to sue violators. It also preempts state laws that conflict with these new federal rules.

Key Provisions

  • Prohibits individuals or entities from making, importing, selling, leasing, advertising, possessing, using, or modifying any SIM box, and from helping others do so.
  • Defines a SIM box as equipment that pools multiple SIMs to obscure call or data origin and bypass carrier controls, with specific exclusions for authorized, government, testing, and other permitted uses.
  • Requires the FCC to adopt implementing regulations within 180 days, publish and maintain non‑exhaustive lists of prohibited and permissible devices, and set procedures for manufacturers to demonstrate exclusions.
  • Mandates coordination with DHS, Customs, the Attorney General, the FTC, and state attorneys general for enforcement and information sharing.
  • Establishes enforcement tools: each violation (including each day of a continuing violation) is a separate offense, the FCC can issue cease‑and‑desist orders, and mobile service providers can bring civil actions for injunctions and damages.
  • Provides a safe‑harbor for mobile providers acting in good faith to detect or mitigate SIM box activity, while limiting liability for unrelated or abusive use of obtained information.
  • Amends forfeiture and privacy provisions to allow seizure of devices involved in prohibited SIM box activity and to permit assistance to federal agencies.
  • Preempts any state or local law that conflicts with the federal SIM box prohibitions, unless the state law is stricter on the same issue.
