Text messages can't always be sent.

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 short 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 messages to 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-three points-settings-more settings-send payment information in the upper right corner. It is recommended to set it to every query.

Second, all short messages can't be sent.

1 Switch flight modes

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

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

There may be compatibility problems with the third-party SMS App, so it is recommended to use the SMS App that comes with the system. Go to Settings-Applications and Rights-Rights Management-Rights-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 using the SIM card of the same operator to check other mobile phones.

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), which can be dialed 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

You can go to Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore All Settings-Restore, Restore Settings Options.

This operation will not delete files or software, but will cancel the password and restore all settings, including the set wallpaper, unlocking style, WiFi, default opening program, etc.
