A GSM jammer is a piece of equipment capable of blocking reception or transmission of cell phone signals. This is mostly done by creating some form of interference at the operating frequency ranges of cell phones, which results in no signal or significant loss of signal quality. Although it could be used practically anywhere, they are mainly used in areas where silence is expected or required.

When a Cell phone jammer is active, most cell phones show no network signal, and when the cell phone jammer is switched off, the cell phone becomes active. Cell phones use unique frequencies for talking and listening. Most of them block either of the two frequencies, indirectly providing the effect of prevention of both. It work on the same principles as that of jammers used in preventing radio communication. They either function by disrupting the cell-phone-to-base-station frequencies or base-station-to-cell-phone frequencies.
