In addition to the mobile phone showing no service, there is another situation where our mobile phone shows that the mobile phone signal is full, but in fact the mobile phone has no signal. Such a situation is that after the mobile phone is in the shielded state, due to the wrong signal state caused by interference, when we use the mobile phone to call someone, the mobile phone will send a request to the nearby base station to search for the signal from the nearby base station to establish a connection. At this point, when we are in the vicinity of the wireless wifi bluetooth jammer, the mobile phone cannot make calls, and the status is connection failure.
