Some individual customers often ask us whether there is such a cell phone signal jammer, which can only achieve jamming signals for a designated cell phone number, and cannot affect other cell phones around the designated cell phone. It is even hoped that even if the designated mobile phone user is far away from other cities, it will interfere with the signal. So, can our mobile phone signal jammer achieve such a function?

The answer is no, the mobile phone signal jammer cannot achieve precise jamming signals for the specified mobile phone number. The reason is: from the basic working principle and method of the mobile phone signal jammer, it only emits interference on multiple mobile phone frequency bands. Signal, this kind of interference signal does not participate in the communication and signaling analysis between the mobile phone and the base station, and does not have the function of identifying each mobile phone number or mobile phone identification code. In the area covered by the interference signal, no matter what number of mobile phone, Regardless of the brand, model, etc. of the mobile phone, the interference signal of the mobile phone signal jammer will act on these mobile phones, which will make these mobile phones unable to answer or make calls normally. Internet access and data services as normal.
