5-band mobile phone signal jammer

The design of the 5-band cell phone blocker device is very light and easy to remove the antenna. There is a separate frequency switch, which can be turned on or off as needed, or it can be placed in a pocket or bag, which is very convenient.

It also has two great advantages:

1. Use GPS satellite positioning and tracking to effectively prevent and protect the location of your privacy and confidential information.
2. Effectively interfere with mobile phone signals such as CDMA / GSM / DCS / PHS / 3G
