Why does the mobile phone always disconnect automatically?

If you use a vivo phone, the data network will be automatically disconnected. You can view the following:

First, the 5G or 4G network is disconnected:

1. One APP is disconnected from the Internet (confirmation method: compare and confirm whether only one APP can't access the Internet and other apps can access the Internet normally);

This phenomenon appears in a single software, while other software works normally because of the software itself. Such as: the server where the software is located, network and other factors. It is suggested to check the network of different operators, or consult the software customer service to find out whether the software itself is in a state of maintenance, abnormality, etc.

2.5G network is not normal.

The 5G network is currently under construction. In order to further improve the stability of the network, operators will optimize and adjust the 5G base station. During this period, if the network is abnormal, both 5G and 4G data networks will be unstable. It is recommended to temporarily turn off the 5G switch before using the view.

Path:

In order to make it convenient for consumers to experience a faster 5G network, some models will turn on the 5G function by default, and the 5G switch will no longer be displayed in the settings.

Method 1: Enter Settings-Mobile Network/Dual Card and Mobile Network-SIM Card Information and Settings-Mobile/China Unicom/Telecom/Radio and Television-Enable 5G-Turn off the switch;
