SMA Female Connectors Cell Phone Signal Blocker Jammer with Individual Switch

GREETWIN jammer is so brilliant , can jam 2G,3G and 4G LTE frequencies. Today with the expansion of 4G networks, especially in USA, UK, Japan and Europe. This jammer goes with lifetime "guarantee" to jam all possible cell phone communications.
