GPS and 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.
