Some people even say that even if the blocked mobile phone user is far away, the signal blocking can continue. Can our mobile phone signal blocker meet such requirements?<\/p>\n\n\n\n<p>The answer is no. Mobile phone signal blockers cannot accurately block a certain mobile phone number. The reason lies in the basic working principle and method of mobile phone signal blockers. The shielding signals emitted by these devices cover multiple mobile phone frequency bands, but the transmitted shielding signals do not participate in the communication or signaling analysis between the mobile phone and the base station, nor do they have the ability to identify specific mobile phone numbers or identification codes. Within the coverage of the shielding signal, all mobile phones, regardless of number, brand, or model, will be affected by the shielding signal of the mobile phone signal blocker, resulting in the inability to make or receive calls and access the Internet and data services.

Whether it is a low-power or high-power blocker, the range of the shielding signal is generally only a few meters to a few hundred meters. Therefore, it is impossible for a mobile phone signal blocker to cross the city boundaries and affect a specific number of mobile phones in another city. It is also difficult to achieve in reality.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h5 class=\"wp-block-heading has-text-align-center\">Best Selling Signal Jammers<\/h5>\n\n\n<div
