Cell-site simulators, often known as Stingrays or IMSI catchers, are gadgets that masquerade as reputable cell-telephone towers, tricking telephones within a certain radius into connecting to the gadget fairly than a tower.

Law enforcement use cell-site simulators to pinpoint the situation of phones with greater accuracy than telephone corporations and without needing to contain the phone firm at all. Cell-site simulators can also log IMSI numbers, ItagPro (International Mobile Subscriber Identifiers) unique to every SIM card, of all the mobile devices inside a given area.
