How do we know if the phone is being monitored?

Open your mobile phone, click Dial, enter the number of your mobile phone card, and dial with the mobile phone card in the number. If you get through, your mobile phone must be bugged.

The normal situation of the above situation should be that your mobile phone is "on the phone". Call again after the phone is turned off. The prompt tone on the phone is delayed, even if it is delayed for about 20 seconds to say "the number you dialed does not exist", you feel that something is wrong. Then your mobile phone has been bugged. At this time, you need to download anti-eavesdropping software or go to the mobile phone shop to disassemble the machine to check whether there are bugs.

Usually, during the call, if you feel the obvious echo of your mobile phone, pay attention, it's not a bad signal, it's eavesdropping.
