There is no signal in the elevator and underground garage in the community.

1, there is no signal or signal difference, 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 change the mobile phone card to the mobile phone of family or friends and try again;

3 Check whether the cell phone signals of other Unicom users around are normal.

2. If you still can't use it normally after self-service troubleshooting, it is recommended that you contact the local manual customer service for verification.
