It can interfere with 3g, 4g, WiFi, GPS and other signals. It is really good value for money. A jammer can shield so many signals. I like it very much.
Review 8 Band Portable Cell Phone Jammer
This jammer is the perfect jammer. As long as the phone is nearby, no signal will be displayed immediately.
As we all know, when it is necessary to make the current phone boring, are cell phone jammers used to block cell phone signals? How I bought it, it will be of great help to you. Moreover, it is very cheap.
Excellent product! I work in a movie theater and we have installed a set of such products. Customers can now enjoy their movies and they are satisfied with it.
