Who would have thought? This device that looks like a smartphone can actually interfere with mobile phone signals. The pocket-sized cellular phone jammer can cover CDMA, PCS, and 3G signals, and can effectively block 2G voice calls, text messages and other basic communications.
The lightweight body design is close to the size and thickness of early smartphones, and it is easy to carry with you. It is almost unnoticeable during use, allowing you to easily achieve unnoticeable shielding operations.
It is necessary to remind you that due to the low power of the device, the P-JM03 is relatively weak in shielding 3G signals. If your core demand is to strongly block 3G communications, it is recommended to use higher power products, such as P-US-06-5, etc.
