    Handheld 3G 4G Cell Phone Jammer / Portable Mobile Phone GPS Jammer Metal Case

    Handheld 3G 4G LTE Cell Phone Jammer / Portable Mobile Phone GPS Jammer Metal Case


    How to use?
    First, please attach the antennas to the body. Then use the charger to charge the jammer before you use it for the 1st time. Please make sure that the jammer is charged for at least 5 hours.

    Once you turn the switch on, devices like cellphones (2G ~ 4G LTE) and WiFi&Bluetooth devices will not be able to transfer any data or make calls within the blocking range.


    The metal case provides a very firm frame and the fan inside makes it possible for long term operation without overheat. Each antennas has its own switch so you can turn them off separately according to your needs (like when you only want to block GSM phones and let CDMA phones work just fine).

    Rechargeable battery inside could provide a working time over 1.5 hours continuously. You could charge the jammer via the lighter in your car or use AC/DC in your home.This tiny device could help those who want to control or block phone use (voice call and internet use) around with very easy steps.

    All you need to do is just to turn the jammer on and it will automatically start to send out jamming signals. Within the functional range, all wireless device, including cellphone, mobile phone, GPS, WiFi device, will not be able to use as long as the jammer is on.
