Shenzhen Huaying Display Co., Ltd. has no signal at all. What happened?

There is no signal on the mobile phone because the signal will be affected by various factors such as topography, landforms and tall buildings. If your location is relatively closed, the signal will be affected. The treatment method is as follows:

1. Shut down again and try again;

2. Replace the mobile phone card with the mobile phone of family or friends and try again;

3. See if there are any signals from other Unicom users around;

If there is no signal, it is suggested that you can contact Unicom's manual customer service for inspection and handling. The actual situation is subject to local policies.
