What is the reason why mobile phone data can't get online?

If you use a vivo mobile phone, you can check the troubleshooting method that the mobile phone cannot turn on or off the data network switch:

1, shut down and restart the phone to see if it is restored;

2. Replace a SIM card (from other operators);

3. Enter Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore all settings. (Important materials are recommended to be backed up in advance to avoid loss. )
