U.S. Immigration and Customs Enforcement has spent hundreds of thousands of dollars on vehicles equipped with “cell site simulators” (also known as “fake cell towers”) that can be used to spy on phones.
The federal agency has long used the controversial fake cell tower devices, also known as StingRays or cell site simulators. The information about them shared in 2026 social media posts references 2024 and 2025 federal contract data.
In July 2026, social media posts claimed that U.S. Immigration and Customs Enforcement has spent hundreds of thousands of dollars on vehicles equipped with “cell-site simulators, also known as fake cellphone towers” that can “impersonate legitimate cell towers, causing nearby phones to connect to them.”
The claim spread via posts on Facebook, which warned that the cell site simulators allow law enforcement to “identify and locate devices in the area” (screenshot, screenshot). According to the posts, a company called TechOps Specialty Vehicles was outfitting the vehicles with the cell site simulators for ICE.
“The surveillance may not stop with the intended target,” the posts said. “Phones belonging to bystanders, neighbors, protesters, journalists, or anyone else nearby could also interact with the simulator during its operation.”
These posts also shared “possible signs” your phone may have interacted with a cell site simulator and alleged ways to reduce the risk of government surveillance via cell site simulators.
ICE did, in fact, spend a total of $1.6 million on vehicles equipped with cell site simulators in 2024 and 2025, according to public government spending data. As such, we have rated this claim as true.
Cell site simulators, also known as StingRays, work by tricking phones into connecting to the simulator rather than a legitimate cell tower, allowing the user of the simulator to collect data such as the content of a text or voice call, websites visited and identifying information, according to Electronic Frontier Foundation, a nonprofit digital rights group.
According to contract information (archived) on the U.S. government’s federal spending website, TechOps Specialty Vehicles provided the cell site simulator vehicles. TechOps Specialty Vehicles did not immediately return a request for more information. According to a 2025 TechCrunch report, the company’s president, Jon Brianas, said the company provides cell site simulators but doesn’t make them in-house.
ICE has a long history of using cell site simulators, which are controversial because they collect information from everyone nearby, not just the intended target. Critics say the devices violate the Fourth Amendment, which protects Americans from unreasonable searches and seizures.
According to the ACLU — which sucessfully sued for public records from ICE on cell site simulator use — the federal agency used the devices at least 466 times between 2017 and 2019. A Buzzfeed News investigation reportedly found that Homeland Security Investigations, an arm of ICE, used cell site simulators 1,885 times from Jan. 1, 2013, to Oct. 11, 2017.
A 2023 report from a federal auditor found that ICE and the Secret Service illegally conducted surveillance using cell site simulators by failing to obtain court orders required under federal law before using the technology. The two agencies also did not adhere to federal privacy policy governing the use of the simulators.
Snopes asked ICE several questions about its use of cell site simulators and associated privacy concerns. We await a response.
How to find the federal contract yourself
A search (archived) for “cell site simulator” on USAspending.gov, the official federal spending website, returned five results, including one contract awarded by ICE. That contract, under ID No. 70CMSD24FR0000115, showed that ICE paid TechOps Specialty Vehicles $1.6 million for “CELL SITE SIMULATOR VEHICLES.”
Under “Award History,” the transaction history indicated that ICE awarded $818,422 to TechOps Specialty Vehicles on Sept. 10, 2024, and an additional $825,708 on May 8, 2025.
While searches for keywords returned no evidence that ICE purchased cell site simulators or cell site simulator vehicles in 2026, it is possible that the agency has purchased cell site simulators under different contract descriptions.
Can you reduce the risk of this surveillance?
Like the claim posts suggest, cell site simulators may drain your phone’s battery, interrupt your service or attempt to drop your phone to a 2G connection. However, these issues can happen for plenty of legitimate reasons. There is very little public information about how commercial cell site simulators work, making it difficult for the public to detect and prevent cell site simulator surveillance.
Some experts and advocates have built advanced tools that seek to detect some versions of cell site simulators. In 2025, the Electronic Frontier Foundation launched an open-source detector called Rayhunter. Researchers at the University of Washington also built a system that detects “anomalies in the cellular landscape” to indicate where and when the surveillance devices are being used.
To protect yourself against cell site simulators, the Electronic Frontier Foundation recommends putting your phone in airplane mode or turning it off entirely. According to the foundation, cell site simulators also can’t read end-to-end encrypted messages, such as those on the private messaging app Signal. In addition, Google and Apple have released features that can help protect users against cell site simulators.
