Cell Site Simulators

Cell-site simulators (“CSS”), also commonly known as IMSI catchers or Stingrays, are devices that law enforcement uses to try to locate specific suspects. However, because CSSs cause the phone to connect to the device rather than the cell tower, they actively interfere in communications between cell phones and towers for every phone in the impacted area, including 911 calls.
