A cell phone jammer is an electronic anti-cell phone signal device, which can conceal and hide the cell phone signal from the cell phone tower by emitting a stronger signal of the same frequency. After the cell phone signal is covered, all cell phones in a specific area will be turned off and out of service. In many public places where cell phones are not welcome, cell phone jammer are very useful to us. Once we have a mobile phone jammer, when we don’t need a noisy mobile phone, we only need to turn on the jammer, and all nearby mobile phones cannot make or receive calls.
How to choose a telephone signal jammer?
1. Make sure you know the frequency of the network. In Africa, Europe, the Middle East and Asia, 900 MHz and 1800 MHz frequency bands are used in most regions.
2. Make sure you understand the local communication service provider. In France, the largest providers are 3G, 4G, CDMA and GSM. Before buying a telephone signal jammer, you should check it on the Internet. The signal jammer can provide you with complete information about the Verizon frequency in your area.
3. Determine the required interference range and application purpose. For smaller areas (such as classrooms), a small and movable area is sufficient. However, if you want to use it in a theater center that can accommodate 10,000 seats, you need to purchase a large-capacity telephone signal jammer with a wide interference range.
