Mobile phone quad-band signal jammer for worldwide use. How does it work? The cellphone jammer transmits low power radio signals to cut off communications between cell phones and cell base stations. It does not interfere with anything other than mobile phones within the 20 meter working radius. Upon activating (turning on) the signal jammer, all the nearby phones will indicate "NO NETWORK", so you can conduct your company presentation, meeting, dinner, worship service, legal proceedings, or other important activities without being disturbed. When the phone jammer is turned from on to off, all cell hand phones will automatically re-establish communications and provide full service. While you may have seen plenty of mobile phone jammers before, this one is quite simply one of the best we have ever tested.
