Cell Phone Blocker

How do Cell Phone Blockers work?

Cell phone signal blockers work by emitting radio frequency signals on the same frequencies used by cell phones. These signals overwhelm and disrupt signals between cell phones and cell towers, effectively preventing communication between them. As a result, phones within range of the jammer cannot make or receive calls, send text messages, or access mobile data services.

Cell phone blockers can operate on a variety of frequency bands, depending on the type of signal they want to block. Some cell phone Blockers target specific frequency ranges used by cellular networks, while others may cover a wider frequency range to interfere with multiple communications technologies, including 2G, 3G, 4G and even GPS signals.
