Vivo suddenly can't connect to the network, but it can call and send text messages, and the network has been disconnected.

If you use the mobile network (that is, the traffic of the mobile phone card) to surf the Internet:

After confirming that your mobile phone card has no arrears and the local network is in normal condition.

① First, you need to open cellular data. Opening method: You can open cellular data in Settings-More Settings-Network.

(2) After opening, you need to display the G or E icon for surfing the Internet at the top of the screen. If it is not displayed, you can turn the phone on and off again.

③ If you still can't access the Internet, I suggest you try to restore the factory settings of your mobile phone: The way to restore the factory settings is: Enter Settings-More Settings-Restore Factory Settings-Restore all settings, and restore all settings without losing the data in your mobile phone.

④ If you still can't access the Internet after trying the above operations, it is recommended that you upgrade your mobile phone before using it. You can upgrade online through wifi: Settings-> More settings-> System upgrade-> Check the update immediately-download the upgrade package according to the prompt, click Check and Install, and the phone will restart, automatically entering the upgrade mode.
