When the SIM card status is abnormal, the signal cannot be detected or the signal is abnormal, the first grid of the signal indicator (signal light 1) will flash, and the other signal lights will be off. The signal value of WiFi can be checked through the system register HSW146 of V-BOX, and the signal value of 2G/4G can be checked by the system register address HSW166.
