    Hello, MacArthur
    A gsm jammer is a device that blocks transmission or reception of signals, usually by creating some form of interference at the same frequency ranges that cell phones use. As a result, a cell phone user will either lose the signal or experience a significant loss of signal quality.
    In addition to GSM, such jammers can also block 2G,3G,4G and upcoming 5G signals.
