Why does my Xiaomi phone show no service after inserting the card

Why does the mobile phone insert the card into the display of no service [question]

1. No signal. The signal of the mobile phone card relies on the "communication base station" transmission, there is an area covered by the communication base station, the mobile phone can have a signal, although the base stations of the major communication operators almost cover most areas of the country, but there are still many areas where the signal is not particularly good, such as the user's location is a remote mountainous area, the mobile phone shows "no service" is normal, because there is no communication base station nearby, or outside the coverage of the communication base station, this situation will occur, change the location and then view, it will be restored.

2. Unstable signal. In addition to "no signal" will show "no service", when the user is in a high-frequency mobile state, it may also display "no service", such as when doing bullet trains, high-speed rail, and airplanes (airplanes are generally not allowed to use mobile phones, but if they are turned on, they may also show no service) will cause the signal to be unstable, and the mobile phone will display "no service", and the mobile phone signal will be restored after the user releases the "high-speed mobile state".
