Indeed, considerable progress has been made in science and technology in the past few years. Nowadays, mobile phones are not only a communication tool, but also a fashion. This is why even a small communication device is not cheap. An easy and effective way to stop communication is to use a cellphone signal jammerer. A blocking device is a device that prevents a mobile phone from being used near the device by transmitting radio waves in the same frequency band as that used by the mobile phone and the PHS.

We use wireless networks almost every day, but what we don't know is that they are not reliable or even dangerous. Many smartphone users are used to connecting free wifi hotspots in public places and using it to browse the Internet and update and process some personal privacy data, such as communication records, bank card information, etc. This is very dangerous, especially Android user. Android's operating system is not SHA1 because it is a weak version of SSL encryption using the RC4 algorithm, so you need a signal jammer. If this signal interception device is installed, the phone will be out of service and cannot make or receive calls.
