CELLPHONE SIGNAL JAMMER/ BLOCKER, PORTABLE-P7,800

Imagine that you are enjoying some much needed peace and quiet at poolside, when suddenly someone nearby gets a cell phone call. So much for your island of tranquility. But, suppose you had your handy cell phone jamming device with you. Would you flip the switch and effectively block all cell phones within range in order to maintain your peace?

Cell phone jammers work by transmiting a low power radio signal to cut off communications between cell phones and cell base stations. It does not interfere with any communications other than cellular phones within the defined regulated zone. Your handy dandy cell phone jammer makes all idle phones indicate "NO NETWORK," while incoming calls are blocked as if the cellular phone were off.

When you're ready to leave the pool, you simply turn off the phone jammer and all cell phones automatically re-establish communications with full service. Only you know why
