In certain specific cases, the use of mobile phones may be restricted. A common practice is to install a full-band shielding device to block mobile phone signals. But there are always people who try to bypass restrictions and restore normal use of mobile phones. Can these shielding devices really be cracked using methods on the Internet?<\/p>\n\n\n\n

To crack the blocked mobile phone signal, you must first understand the working principle of the full-band shielding device. These devices emit white noise signals with the same frequency as the mobile phone signal, interfering with the mobile phone’s reception of base station signals, resulting in no signal and limited use of the mobile phone. The range of the shielding device depends on the transmission power of each module in the device and the signal strength of the base station used. In theory, the greater the transmission power of the full-band shielding device, the greater the shielding range. Conversely, the stronger the base station signal, the smaller the shielding range of the device. Cell phone jammers<\/a> and GPS jammers<\/a> worth buying.<\/p>\n\n\n\n

In theory, it is quite difficult to crack such devices. Although there are still methods on the Internet, they are generally ineffective.<\/p>\n\n\n\n

Here is a cracking method provided by a professional manufacturer for reference only:<\/p>\n\n\n\n

There are only two ways to restore the mobile phone signal within the coverage of the full-band shield without damaging the device. One is to move the mobile phone out of the coverage of the shield, and the mobile phone signal will recover naturally. The second is to use the mobile phone normally within the shielding range of the full-band jammer, and at the same time enhance the transmission signal power of the base station to enhance the mobile phone signal within the shielding range, thereby reducing the shielding range of the full-band jammer and restoring the mobile phone signal. However, this operation is also difficult. It takes careful consideration to establish a base station. The signal strength emitted by the base station needs to be enhanced in many ways, and it cannot be based on personal preference alone.<\/p>\n\n\n\n

The online references often involve a series of mobile phone settings, such as changing the network settings to manual search. However, whether it is automatic network search or manual network search, it is necessary to connect to the base station for communication. In actual applications, these methods cannot successfully restore the mobile phone signal, and the mobile phone still shows no signal.<\/p>\n\n\n\n
