Is there a combination GSM 3G 4G jammer?

Hello, Eden. Your request sounds very unique, and it's much more demanding than normal full-spectrum jamming. You should know that general GPS location tracking, in addition to the GPS tracker may be located, it may also be sent by the phone's APP. But you want to keep the phone's normal communication function, which is much more complicated. Obviously, a normal handheld jammer won't do what you need. You may need an advanced cell phone jammer that controls each band individually
