The HJ-03 is a mini pocket GSM jammer that can optionally be used with 3G signals or GPS signals against GSM, CDMA and 3G signals (or GPS signals). It's smaller, probably smaller than your smartphone, so it can even be tucked away in your pocket. Due to its low power output, the working radius is only 5 meters, but it is enough to prevent many digital threats such as surveillance, eavesdropping, theft of private information, illegal location tracking, etc.

This HJ-03 signal blocker is also one of our oldest 3G jammer models, but it's still one of our best sellers. Many people still want to choose this model due to its rather low price and excellent specifications.
