Why does the black shark get disconnected on the phone?

The signal strength is unstable and the network setting is wrong.

1. Unstable signal strength: Black Shark's mobile phone needs a cell phone signal or WiFi network to make a call. If the signal strength is unstable or the network quality is poor, it will lead to network interruption or poor call quality.

2. Network setting error: for example, Black Shark mobile phone network setting error, such as APN setting error, data roaming not turned on, etc. The network will also be disconnected when you make a phone call.
