Vivo SMS can't be sent out. What happened?

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

1. Some short messages could not be sent.

1. Confirm whether the phone bill balance is sufficient.

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

Please send short messages with test sentences to confirm whether the other party can receive them 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-(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).
