I have been in Xuancheng, Anhui for three months. What happened to travel itinerary?

Because of network problems. 1. This situation may be caused by poor ambient signal or signal blind area. At this time, no signal is normal. It is recommended to move around to find a place with good signal or leave the signal blind area. 2. It is also possible that the system that comes with the mobile phone is out of order. At this time, you can turn off the phone and turn it on again, so that the phone can automatically connect to the network. 3. In addition, it is also possible that the local mobile operator may have problems with the signal transmission tower for some reasons, such as thunderstorm weather and typhoon weather. In this case, operators can only wait for emergency repair before accessing the network.
