Mobile phone information can't be sent, how can I get back to normal?

If you use a vivo phone, you can refer to the following methods for troubleshooting:

1. Confirm whether the phone bill balance is sufficient.

Please confirm whether the phone bill of the mobile phone card is sufficient. If the phone bill is not enough, sending SMS will fail.

2. Switch flight modes

You can try to switch flight modes, re-trigger the network and try again.

3. Check whether to use a third-party SMS APP.

Third-party SMS applications may have compatibility problems. We suggest that you use the SMS app that comes with the system, go to Settings-Applications and Permissions/Multiple Settings-Permission Management-Permissions-Default Application Settings-Information, and set it as Information.

4. Check whether the number of the SMS center is set correctly.

Enter information-click on the dot in the upper right corner-Settings-More Settings-SMS center number. If you don't know the local SMS center number, contact the operator to get the SMS center number and set it.

* Note: You can also check the number of the local SMS center by checking other mobile phones using the SIM card of the same operator.

5. Compare and test SIM cards

Test that you put the SIM card on other mobile phones to send text messages. If it still fails to send, it is recommended to consult the operator's customer service.

6. Restore all settings

You can go to Settings-System Management-Backup and Reset-Restore All Settings-Restore and Restore Settings. This operation will not delete the media file, but will cancel the password and restore all settings, including the set wallpaper, unlocking method, WiFi, default opening program, etc. Logged-in software accounts also need to log in again.

Note: Enter Cloud Service-Device Cloud Backup-Backup Data Type-System Data-Back-Back up some backup system settings and desktop layout immediately; Cloud service-data synchronization-turn on WLAN and Bluetooth to synchronize data to cloud service.
