Can the mobile phone signal jammer block the signal of a specified mobile phone number?

Many individual customers often ask if there is a Cell Phone Jammer that can accurately block a certain mobile phone number without affecting other nearby mobile phones. 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?

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.

It should be emphasized that the shielding signal emitted by the mobile phone signal blocker has limited power and limited transmission range.

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.
