ICE Spent $825,000 on Vehicles Equipped with IMSI-Catchers

U.S. Immigration and Customs Enforcement (ICE) paid $825,000 this year for vehicles fitted with cell-site simulators (IMSI-catchers), according to public-contract reporting covered by TechCrunch. These devices impersonate cellular towers to collect identifiers, location, and potentially intercept phone data from all devices within range.

What are IMSI-catchers?

• IMSI stands for International Mobile Subscriber Identity, a unique identifier for each cellular user.
• Cell-site simulators (aka “stingrays”) act as fake cell towers to force nearby phones to connect, enabling location tracking and data interception.
• There are passive and active variants: passive devices are less intrusive; active devices can intercept calls, messages, and data streams.

Key concerns

• Warrantless use can sweep data from innocent bystanders, raising Fourth Amendment issues.
• Active IMSI-catchers can disrupt emergency calls (e.g., 911), posing safety risks.
• Transparency and oversight are limited — civil liberties groups such as the ACLU and EFF have raised alarm and developed detection tools.

Who supplied the vehicles?

TechOps Specialty Vehicles supplied the vans under contract to integrate the simulators; the government agency buying the equipment was ICE.

Are these devices sold to consumers?

No reputable retail platforms (e.g., Amazon) sell legitimate IMSI-catchers for general consumers; these tools are restricted and typically used by government or law enforcement.
