Why can't the mobile phone send text messages?

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

1. Some short messages cannot be sent

1. Confirm whether the phone bill is sufficient

Please confirm whether the phone bill of the mobile phone card is sufficient. If the phone bill is insufficient, sending short messages will fail.

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

Please, send a short message with a test statement 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 has been started

After fixed dialing is started, 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 to SIM card-fixed dialing, and turn off fixed dialing (you need to consult the operator when turning off the PIN2 code)

4. You can't send short messages to some short numbers

Please go to the information APP-- 3 o'clock in the upper right corner-Settings-More settings-and send payment information.

2. All short messages can't be sent

1. Confirm whether the phone bill is sufficient

Confirm whether the phone bill of the mobile phone card is sufficient. If the phone bill is insufficient, sending short messages will fail.

2. Switch flight mode

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

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

There may be compatibility reasons in the third-party SMS APP. It is recommended to use the SMS app that comes with the system, and set it to Information in Settings-Applications and Permissions/More Settings-Permissions Management-Permissions-Default Application Settings.

4. Check whether the SMS center number is set correctly

Enter the information-click 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.
