Have you ever had any phone tapping? I'm a government employee, and we will several important meetings recently, and given the security of information, we need to prevent eavesdropping. Will mobile phone become the medium of wiretapping? How to avoid phone tapping?
This happens all the time. Thanks to advances in technology, the phone-tapping order can now be accessed via the phone's APP, so it could be tapped if your phone or the smart device around it starts.
In the face of this situation, we can usually use the WIFI cell phone jammer. When the device is turned on, it can quickly block the phone and wireless signals around it so that they can't tapping. Confidential information can be effectively protected.
First of all, do you have to know where it came from
If it's from inside the phone, you need a jamming device that interferes with a variety of cell phone signals. If it comes from the outside, then you need a jamming device that can interfere with WIFI and radio signals.
