Turn off the wifi and 3g, then it will just stop the phone's signal. What functions you need, what functions you don't need, now you can use the swith to make what you need.

Powerful and effective, this portable signal jammer effectively disables any nearby WiFi and 3G networks, as well as other cell phone signals (GSM, CDMA, DCS, PHS 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 unjamming. 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.
