This jamming pouch is great for blocking one or two particular cell phones. The phone will not ring inside the case. The signal is automatically reconnected once it is removed from the bag. Depending on your operator's network configuration, callers will hear a "temporarily unavailable" message instead of "cell phone is off" type message.
This jammer is very reliable and blocks the widest range of frequencies. This model is ideal for medium sized rooms that need to be cell phone free. This jammer is also one of the few models that can be charging while in use. 60FT 3-in-1 Phone, WiFi, and Bluetooth Jammer Specs: Blocking Radius: 70-110 Feet (Cell Phone Type and Network May Cause this to Vary) Car Charger: Included Standard
