Blocking a single caller can be a waste of time. The mobile jammer can block all incoming calls at once, thus eliminating the trouble.

If successful, the phone will no longer receive signals at a specific location. People use jammers for several reasons. Business owners may wish to block their employees’ cell phone signals to prevent interference or interference in the workplace during meetings. The jammer also prevents the phone from sending outgoing messages. People may use jammers to prevent the leakage of sensitive information. This is also a useful way to stop signals to prevent terrorist attacks. People also like to use jammers because they send out an “out of service” message instead of a “phone is down” message. This makes the caller seem unable to reach the phone owner. There are many different devices that can block the phone like this.
