Powerful and effective, this portable signal jammer effectively disables any Wi-Fi networks and mobile phone signals (on the 2G [GSM, CDMA, DCS and PCS], PHS, 3G and 4G LTE 1800 bands) without interrupting any other electronic devices. The highly portable size and one-touch power button allows users to quickly turn the device on or off for instant jamming and un-jamming. Incredibly easy to operate and carry around, this portable signal jammer is both the ideal security and anti-security device and quite simply one of the best we have ever tested.
