What is the function of the mobile phone signal jammer of 3G signal?

3G has already begun to be canceled in many countries. Verizon announced that it will finish shutting down its 3G network by December 31, 2022. T-Mobile announced that it finished shutting down Sprint's 3G CDMA network as of March 31, 2022 and Sprint's 4G LTE network as of June 30, 2022.

Verizon is the only wireless provider whose service is still up and running. After AT&T and T-Mobile completed shutdowns of their 3G wireless networks in the first six months of this year, Verizon remained as the only provider of the nearly obsolete service. Verizon will discontinue its 3G network at the end of 2022.

But many remote areas still use 3G networks, such as rural areas. And these mobile devices are relatively backward, and local operators will delay the use of 3G. The cost of 5G is relatively high, which is not conducive to mass use. At the same time, many tracking devices use 3G and 2G signals to transmit data, which is good for cost control.

How to use the 3G cell phone signal jammer?

Dedicated 3G mobile phone jammers are almost non-existent. Generally, it will only exist in jammers dedicated to tracking systems, or 4G 5G jammer devices. To choose a 3G signal jammer, we only need to purchase according to the demand, and the 3G frequency bands all over the world are blocked in the same way. So there is no need to distinguish between countries.
