The latest smartphones work well, but I've had moments of despair in places like libraries and grocery stores. There are many stories about the wide use of mobile phones, but there are annoying uses, and we are very distressed by the noise of mobile phone calls. There are many stores of GSM jammers. A radius of 10 feet may block the reception of mobile phones. This product is a way to suppress phone signals.
The use of mobile phones poses a security threat in military settings. Advanced security facilities use signal jamming equipment to prevent unauthorized communication. We are taking measures to prevent GPS reception, mobile phone communication, etc., which will cause strong interference in the same frequency range. We recommend that you take security measures to improve security. Such as the use of wireless jammers to protect network information security, countering violations of information confidentiality.
You can use this jammer to protect your privacy. It is forbidden to send messages within its scope, to prevent noise, and to use mobile phones on the train to eliminate violations. If you want to use a GPS jammer, you need to obtain a license under certain conditions.
