A hand tour, text message or phone game will disconnect you. How to solve it?

There are generally three situations when a mobile phone is disconnected:

1. Strong interference of radio waves will lead to disconnection. Because mobile communication is spread by radio waves, when some radio waves interfere with the radio waves in use to a certain extent and the signal-to-noise ratio drops below the standard value, the mobile phone will automatically turn off and drop the line.

2. Transmission is blocked and buildings reflect, which will interfere with the radio waves at the receiving point and cause disconnection.

3. When the handover fails, the user's voice channel needs to be switched from the original cell to the new service cell, but the busy and idle time of the user in the new service cell is also random. If there is no effective voice channel to provide during the handover, the handover will fail, resulting in the disconnection of the mobile phone. If the call is suddenly dropped, you can move and change the location to avoid using it in a dead corner.
