Hi, this is actually quite simple. We just need to block or cover the cell phone signal.
The current phone signal blocker are all frequency bands, which can block all 2G 3G 4G signals, 2.4G WIFI signals and Bluetooth signals. frequency, so as to achieve the purpose of shielding them.
Therefore, as long as the jammer is turned on, the mobile phone cannot make calls, send and receive text messages, and surf the Internet.
This cannot be avoided by any number and band cracking, because no matter which number or band you use, it is within its shielding range.
There is also bluetooth software, because its frequency will also be blocked by the blocker.
