Why can't I send text messages?

If you are using a vivo phone, you can refer to the following troubleshooting methods:

1. Some text messages cannot be sent

1. Confirm whether the phone bill balance is sufficient

Please confirm whether the credit on your mobile phone card is sufficient. If the credit is insufficient, sending text messages will fail.

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

Please use test statements to send text messages to confirm whether the other party can receive them normally, such as: 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 turned on

After turning on fixed dialing, messages can only be sent to contacts in the fixed dialing list and cannot be sent to other numbers. If you want to continue sending text messages, please cancel the fixed dialing service. Enter Settings--(Applications and Permissions)--System Application Settings--Phone--Corresponding SIM Card--Fixed Dial, turn off fixed dial (the PIN2 code that needs to be entered when turning off needs to be consulted with the operator)

4. Unable to send text messages to some short numbers

Please enter the message APP--three dots in the upper right corner--Settings--More settings--Send paid messages. It is recommended to set it to ask every time.

2. All text messages cannot be sent

1. Confirm whether the credit balance of the mobile phone card is sufficient

Confirm whether the credit balance of the mobile phone card is sufficient. If the credit balance is insufficient, sending text messages will fail.

2. Turn flight mode on and off

You can try turning flight mode on and off and re-triggering the network before trying.

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

Third-party SMS APP may have compatibility reasons. It is recommended to use the system’s own SMS APP and go to Settings--Applications and Permissions/Updates Multi-settings--Permission management--Permissions--Default application settings--Information, set to information.

4. Check whether the SMS center number setting is correct

Enter the information--click the dot in the upper right corner--Settings--More settings--SMS center number, if you do not know the local SMS center number, please contact your operator to obtain the SMS center number and set it up.

*Note: You can also check the local SMS center number by checking other mobile phones around you that use the same operator's SIM card.

5. Comparative test of SIM cards

It is recommended to put the SIM card on other mobile phones to send text messages for testing. If the sending still fails, it is recommended to consult the operator's customer service.

6. To restore all settings, you can enter Settings--System Management/More Settings--Backup and Reset/Restore Factory Settings--Restore All Settings--Restore and restore settings options.

This operation will not delete the software or files, but will only reset all setting options. For your data security, you can back up important data before operation.

Note: Enter Cloud Service--Device Cloud Backup--Backup Data Type--System Data--Return--Back Up Now to back up some system settings and desktop layout; Cloud Service--Data Synchronization-- Turn on WLAN, Bluetooth, etc. to synchronize data to cloud services.
