Although the 4G cell phone signal jammer has been born for 9 years, it is still the hottest cell phone jammer product. Many countries have not popularized 5G, and even 4G is not common in many remote areas. Therefore, the 4G signal jammer is still the most popular product at present.

How does 4G jammer work?

The 4G jammer works by sending radio frequencies to the same tower. It will overpower the cell phone signal by mimicking your cell phone. Basically, it sends out a signal that is the same frequency as your phone. This signal is powerful enough to outmuscle your phone's signal.
Usually, most mobile phone signal jammers only need to install the corresponding antenna correctly according to the antenna mark and turn on the device with a full charge. At this time, the device will run for a few seconds, and the mobile phone signal will not be received normally.

How to choose a 4G cell phone jammer?

4G devices usually need to determine the mobile phone signal operator in the area of use, such as 4G LTE and 4G WIMAX.
If you don't know, you can choose a dual-signal device. The number of antennas generally requires at least 5.
