How to Use a Cell Phone to Jam Signals
If your cell phone contains a Global Positioning System (GPS) feature, it can be used to track you and hone in on your location. A phone with GPS is constantly giving off its location, not just when you use the GPS feature or contact emergency services. To hide your location and stop this transmission, utilize a cell phone accessory known as a cell phone jammer.
Purchase a cell phone jammer, which will stop your cell phone from sending and receiving signals. Top-of-the-line jammers block out cell phones in an estimated 100-foot radius from sending signals to a cell phone tower. More modest jamming devices cover a 15-foot radius.
Jam the signal by turning the device on. Some jamming devices utilize a flip feature, while with others you just click a button. The jamming device is about the same size or a little smaller than a standard cell phone. Also, ensure that the jamming device is close by to your cell phone for it to work properly.
Turn off the jammer when you are done using it. This is important because there is the potential to jam and interfere with other radio signals in immediate area.
