Zhaotong Unicom has no signal for several days.

Tips: Watching videos will consume traffic. I suggest you watch it in wifi environment. Please pay attention to the traffic situation at any time! ?

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 change the mobile phone card to 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, you can contact the online customer service in the province where the number belongs to verify the specific reason.
