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. Additionally to this it is able to jam GPS and WIFI frequencies which actually makes this jammer to be you all-in-one jamming solution. Another great innovation is a separate DIP switch for each band. it can jam all 8 frequencies continuously and simultaneously, or block only chosen frequencies. So if you need to jam only GPS frequencies, let's say in your car, and you would like to have an opportunity to use your cell phone during your ride, just switch on the GPS on the body of jammer and only GPS frequencies will be jammed. By the way, GW-JN8L goes with car power network adapter, so you can use it in your car for long time.
