When the mobile phone is within the effective shielding range of the mobile phone signal jammer, the phone's voice call function and Internet data transmission and other functions will be cut off, and the signal grid on the top of the display screen will also disappear. At this time, the mobile phone is completely offline , Basic functions such as answering or making calls, sending and receiving text messages, chatting online, and playing games online cannot be used normally. At this time, some customers will ask questions: If the mobile phone signal jammer is turned off, how long will it take for the mobile phone to return to normal? Is it true that the mobile phone signal will be restored immediately when the mobile phone signal jammer is turned off?

The facts may be different from your initial assumptions: the mobile phone signal jammer has two different states of action on the mobile phone at the moment of turning on and turning off.

Let me first talk about what happens when the mobile phone signal jammer is turned on: as long as the mobile phone is not far away and does not exceed the effective shielding range of the shielding device, then at the moment of turning on the mobile phone, the communication functions (including voice and data) will be disabled. Immediately blocked, with almost no time difference between the two. Although some people may find that the signal grid does not disappear quickly or drop to zero when observing the signal grid on the mobile phone screen, but in fact the signal grid at this time is just a false display. Operate the mobile phone, trigger the external communication function of the mobile phone, and you will find that the display of the signal grid will quickly complete the status update.

Let's talk about the performance process of the mobile phone signal jammer that was originally shielded by the signal when it was turned off or cut off the power supply after the mobile phone signal jammer was turned on for a period of time? Through observation, it can be found that the moment the mobile phone signal jammer is turned off, the mobile phone does not respond in a short period of time, and it is not possible to answer or make calls immediately, and it is not possible to quickly use the mobile phone to access the network. The signal grid is still displayed as no signal for a period of time at the beginning. Mobile phone users can only see that the signal of the mobile phone has finally recovered after waiting patiently for more than ten or even twenty seconds, and then they can use the mobile phone completely and normally. Why is this so? This is because after the mobile phone signal jammer is turned off, the signal recovery of the mobile phone must go through a process, that is, the process of handshake communication between the mobile phone and its surrounding base stations, identification, and registration to the network. The length of this process will be affected by several factors. Factors, including: different operators of mobile phones, different strengths of base station signals, different numbers of mobile phone users in the service area to which base stations belong, and so on.
