Why can't the mobile phone send a message?

If the vivo phone cannot send information, please refer to the following methods for troubleshooting:

1. Some short messages could not be sent.

1. If the short message contains sensitive words, the other party cannot receive it after sending it.

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

2. Confirm whether the "fixed dialing" service is enabled.

When 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-Applications and Permissions-System Application Settings-Telephone-Mobile/Unicom/Telecom-Fixed Dialing, and turn off Fixed Dialing (please consult the operator for the PIN2 code to be entered when turning off).

3. Unable to send short messages to some short numbers.

Please go to the information App-3 o'clock in the upper right corner-Settings-More Settings-Send payment information. It is recommended to set it to every query.

Second, all text messages can't be sent.

1, switch flight mode.

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

2. Check whether to use a third-party SMS App.

The third-party SMS App may have compatibility reasons, so it is recommended to use the SMS App that comes with the system. Go to Settings-Applications and Permissions-Rights Management-Permissions-Default Application Settings-Information and set it as Information.

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

Enter Settings-Applications and Permissions-System Application Settings-Information-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.

The contact numbers of the four major domestic operators are: 10099 (China Radio and Television), 10086 (China Mobile),10 (China Unicom) and 10000 (China Telecom), so you can call them in time.

4. Compare and test SIM cards

It is recommended 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.

5. Restore all settings

Go to Settings-System Management-Backup and Reset-Restore all settings, and then follow the onscreen instructions.

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.
