Why does texting always fail?

1. Some short messages cannot be sent:

1, please check whether the number of the received information is accurate, whether it is 1 1 digits, and there are no spaces before and after the number.

2. 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: 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. 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).

4. 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. Query the phone bill balance

If the mobile phone card is in arrears, the short message cannot be sent successfully.

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

There may be compatibility reasons for the third-party SMS App, so it is recommended that you 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.

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, please contact the operator to get the SMS center number and set it.

Check other mobile phones around you that use the SIM card of the same operator, or check the number of the local SMS center.

5. Compare and test SIM cards

It is recommended that you put the SIM card on other mobile phones to send SMS test. If the transmission still fails, it is recommended that you consult the operator's customer service for handling.

6. 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 media files, but only restore all settings of the phone. Some third-party application accounts need to log in again. Please ensure that the use of the software will not be affected before operation.

7. You can go to the service center with your mobile phone, ID card and valid purchase certificate, enter the browser to search for vivo official website-Services-Service Center-View All-select provinces and cities to inquire about the address and contact information of local service centers.
