Why did the network request go wrong when Baguikang's literacy knowledge entered Wanjia?

There are many reasons for network request errors, such as poor cell phone network signal, web page loading problems and so on.

The reason for this is the following：

1. Please confirm whether the SIM card type of the mobile phone corresponds to the network type supported by the mobile phone.

2. Make sure that the SIM card of the mobile phone is not in arrears (this situation is most easily overlooked).

3. Enter the mobile phone settings, mobile network and access point name, and then click Select to try to reset to the default settings.

4. Check whether there is traffic monitoring software (including the network assistant that comes with the system) that forcibly shuts down the network. If there is, you can cancel the upper limit of flow or adjust it to an appropriate value.

At present, most software and web pages need to use network access points. If the connection fails, try changing the access point to a network.
