There are many types of signal jammer for cell phone brands in our lives, but they can basically be divided into two categories: one is engineering machinery, and the other is ordinary machinery. As the name suggests, engineering machines are generally used for projects with high requirements, high standards and high indexes. Their characteristics require very stable performance and 24-hour uninterrupted operation. Ordinary phones, for general home use, have limited performance and may affect the use of other people's signals.
So, how to use a mobile phone signal jammer?
First, make sure that the jammer for sale you use is legal.
Second, try to choose engineering machines with reliable performance.
Third, ask a professional team to install it to ensure that it is within the shielding range and does not affect others around you.
Fourth, turn on the power and run the machine, and the signal will be automatically shielded within the shielding range.
