As we all know, mobile phones are increasingly becoming an integral part of our lives. It can bring us convenience and negative consequences. To prevent this bad effect, various types of cell phone signal jammers are presented in the market. It can meet different needs and avoid mobile phones from affecting our lives. It is the best choice to ensure that we use mobile phones efficiently. Because it can cut off the 3G 4G signal of the mobile phone without your knowledge, and many strong mobile phone jammers can set one or more signals independently, it will not affect the use of other mobile phone signals, which is very convenient.

While advanced cell phone jammers can block multiple types of networks at the same time, cut off dual-mode or triple-mode cell phones, and switch between networks. and find a closing signal. Some high-end jammers can block all frequencies at once, while other cell phone jammers can be set to block specific frequencies.

To jam your cell phone signal, all you need is a device that can broadcast on the correct frequency. GSM networks for digital and PCS cellular systems operate at 900 MHz and 1800 MHz in Europe and Asia, and 1900 MHz (sometimes 1.9 GHz) in the US. Jammers can broadcast on any frequency and are ineffective against AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN and Nextel systems. Old-fashioned analog telephones are just as easily disturbed as today’s digital telephones.

The practical range of a GSM jammer is related to its power and external environment (eg slopes, walls, etc., which can block the jamming signal). Low-power jammers can block phone calls within a radius of up to 30 feet. High-powered equipment can turn the size of a football field into a no-signal zone, and equipment used by law enforcement can cut off service within a mile radius.
