What's the matter that vivo mobile phones can't send short messages?

Case 1: Some short messages cannot be sent.

1. 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. Please use the test statement to send a short message to confirm whether the other party can receive it normally, such as sending: Hello, thank you, etc. If the other party can receive it normally, it means that the text message sent before may contain sensitive words.

3. After fixed dialing is turned on, you can only send information to the contacts in the fixed dialing list, but not to other numbers. If you want to continue sending SMS, please cancel the fixed dialing service. Enter settings-(application and permissions)-system application settings-telephone-corresponding SIM card-fixed dialing, and close fixed dialing (you need to input PIN2 code and consult the operator when closing).

4. If you can't send short messages to some short numbers, please go to the information App-three points in the upper right corner-Settings-More Settings-and send payment information. It is recommended to set it to every query.

Situation 2: All short messages can't be sent.

1. 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. Try to switch flight modes, trigger the network and try again.

3. Third-party SMS applications may have compatibility problems. It is recommended to use the SMS app that comes with the system, and go to Settings-Applications and Permissions/More Settings-Permission Management-Permissions-Default Application Settings-Information and set it as Information.

4. 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, please 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. It is suggested to put the SIM card on other mobile phones to send SMS test. If it still fails to send, it is recommended to consult the operator's customer service.

6. Enter Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore All Settings-Restore.

Note: Restoring all settings will not delete any data or media files, but only restore all settings of the mobile phone, and some third-party application accounts need to log in again. Please make sure that it will not affect the use of the software before operation. For the safety of mobile phone data, it is recommended to back up mobile phone data in advance before operation. (You can go to 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-enable WLAN, Bluetooth, etc. Synchronize data to cloud services)

7. If the above methods can't be solved, please back up the important data of the mobile phone in advance and take it to the vivo customer service center for testing and processing.

Tips: It is recommended to bring relevant purchase vouchers (such as purchase invoices/warranty cards/ID cards) when you go, and call the service center staff in advance to ensure that the staff will go again during normal working hours, avoid running empty, and pay attention to safety on the way back and forth.
