Many people are at a loss when shopping. This is the reason for the lack of understanding of product features and specifications. Some people say that the purpose of buying things is unclear.

I have a question like this. In order to solve these problems, today I want to talk about portable mobile phone jammers and fixed jammers. Customers will find it helpful when choosing this product.

Both can block different radio waves. It can suppress GPS, WIFI, 3G, 4G, GSM and other signals. Next, I will explain the difference. The range of blockade is different.
