I was excited when I first received this cell phone jammer but a couple of things to note before you spend your money: This device "eats" the caller id number and does not pass it along to your telephone. If you depend on the caller id, this device will "block" it. This can cause you to miss calls you really need
Reviews About N12 Mobile Phone Signal Blockers
I bought one and it worked well. Thanks to this product, I can now block 4G LTE and 4G Wimax signals at the same time and create a quiet environment.
The powerful features of this device made me buy it. The huge coverage radius and the adjustment of the output power of each antenna can cause interference to frequencies within the specified range. I can set it to block only one frequency (such as Wi-Fi) and use other frequency bands freely. Powerful and flexible household equipment can shield equipment!
I have been persecuted by retaliated federal officials for more than 20 years. There is a tracker on my truck, where people can follow me, harass me electronically, break into my home and take other Nazis away. When I use mini GPS jammers, they will not follow. Then I put the phone in airplane mode and told my wife the same thing.
