S.2522

Cell-Site Simulator Warrant Act of 2025 regulates cell-site simulator use by requiring warrants and limiting evidence admissibility.

The Cell-Site Simulator Warrant Act of 2025 amends the United States Code to require warrants for using cell-site simulators, except in specific circumstances. It prohibits unauthorized use of these devices, which mimic cell towers to intercept communications. Warrants must specify the simulator's operational area and duration, and courts must weigh law enforcement needs against potential negative effects. Evidence obtained without a warrant is generally inadmissible.
