Collection: Cell Phone Signal Blocker Jammer

Cell Phone Signal Blocker Jammer operate by emitting radio signals on the same frequency as cell phone signals. This interference disrupts the incoming cell phone signals, causing mobile devices to be unable to connect to the cellular network. As a result, the device is unable to make or receive calls, send or receive text messages, or connect to the internet.

The effectiveness of cell phone jamming blocker depends on several factors, including the power output, frequency bands, and range of the device. Some cell phone jammer can block all frequency bands used by mobile phones, while others can only block specific frequency bands. The range of a cell phone jammer also varies depending on the environment. In an open area, the range can be up to 30 meters, while in an enclosed area, it can be as low as 5 meters.
