LMGSMSafe: Cell Phone Frequency Monitor

It does not take a whole lot to spy on you. A cell phone can easily pick up your private conversations if you are not careful. That’s where LMGSMSafe can be so helpful. You just have to put your phone in the box for the LMGSMSafe to activate and monitor all transmissions your phone makes. The LMGSMSafe will detect GSM, CDMA850, 3G, and Bluetooth signals. When a signal is detected, the LED will flash with the color associated with its protocol.

This device can also be used to create a white noise to mask any sound your phone’s microphone may pick up. The battery life should last you up to 15 days. Not cheap but can help protect your private information.
