If necessary, you can use flexible controls to block the signal bar. The 7.4v/3600Ma/h lithium ion battery can be used for a long time. After turning on the mobile phone jammer, you can charge it. Life is very convenient. In addition, it is an adjustable signal jammer that allows you to select a frequency type that cannot be used at any time. If necessary, you can use flexible controls to block the signal bar. The 7.4v/3600Ma/h lithium ion battery can be used for a long time. After turning on the mobile phone signal jammer, you can charge it. Life is very convenient. In addition, you can choose a frequency type that can adjust the mobile cell phone jammer, which will not work at any time. If necessary, you can use flexible controls to block the signal bar.
The adjustable cell phone signal jammer allows you to choose the type of frequency that stops working at any time. If necessary, you can use flexible controls to block the signal bar. The adjustable cell phone signal jammer allows you to choose the type of frequency that stops working at any time. If necessary, you can use flexible controls to block the signal bar. Now, you can turn it off politely and go again, or you can buy cell phone jammers and leave them alone.
The basic principle of a mobile phone jammer is to emit the same radio frequency signal as a mobile phone. Because the frequency is the same, the mobile phone cannot distinguish which signal is a regular base station signal, thus realizing “interference”. As long as there is a machine with the same frequency as the phone, when the base station tries to connect to the phone, a lot of “noise” will be generated. You will find that the phone signal cannot be recognized, so you will refuse to communicate with the phone. Initially, mobile phone jammers can only block a set of frequencies, such as 2G, while complex mobile phone jammers can simultaneously block multiple types of networks, such as 2-3-4-5G.
