A man ask us a questions: “My insurance put a black box in my car it has a built in gps and tracks my speed I want to block the whole thing”?
First of all, we will analyze the way this box how to achieve positioning and tracking.
The insides (IMEI number covered up–Off-the-shelf GSM module by Telit):
So it is a dual-core positioning device: GSM+GPS both! So you need a jammer which can block GSM(GPRS)+GPS both because when you only block the box GPS with a mini gps jammer, then it will automatically active achieve GPRS GSM positioning through the built-in SIM card.
Maybe you will have a question: GSM blocker would block the signal.. it would also block your phones signal lol?
Yes, it will only block GSM signal but there is no impact on the 4G signal, so you can answer and make a phone call.
