Cell phone tracking might be of various types and I guess you would like to discover more about them. The most commonly used type of cell phone tracking is GPS tracking with the help of embedded GPS tracking chip of your smartphone. Using this chip government can track your smartphone location. To avoid this type of tracking you can use GPS jammer. But there are many other, more complex ways of tracking your cell phone.
More complex way of tracking your cell phone is called A-GPS technology. It uses not only GPS navigation of your cell phone but also cell phone towers as an additional source of location information. Together those technologies can quickly and easily triangulate your location, starting from the position between cell phone towers and then determining your location more precisely via GPS tracking. You need to use pocket GSM/GPS jammer in order to avoid this type of tracking.
If you have a smartphone with the WiFi connectivity, company called Septier will be able to use it in order to track your location, and in the nearest future they will be able to track you even indoors. So it would be great for you to block WiFi frequency in this case.
As the bottom line I can say that if your cell phone has all of the technologies I have mentioned then instead of carrying around all those jammers for separate frequency blocking you can use the best cell phone jammer we have and select what frequencies you need to block and what to leave in the working condition.
I hope that this information will help you to prevent anyone from tracking you through your cell phone because nowadays even President Obama wants to track you and CIA Director is happy to track you too.
Be safe! ;)
