Huawei can't send text messages

1. "Enhanced Information" cannot be sent.

If "enhanced information" is displayed in the SMS edit box, it means that the mobile phone is sending a short message with enhanced information, which can be handled by the following methods:

1. Please turn off and turn on the enhanced message switch (SMS) again; Three-point button "Settings" enhanced information).

2. If you need to contact the other party urgently, I suggest you turn off the enhanced information function first, and then send the information by ordinary SMS, so that you can contact the other party in time.

3. If it is still unresolved, it is recommended that you consult the operator.

Second, some short messages can't be sent.

For example, send short messages to operators (China Mobile/KOOC-0/0086, China Telecom/KOOC-0/0000, China Unicom/KOOC-0/00/0). If the short message is sent successfully, it means that some short messages cannot be sent.

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

Please use test statements to send short messages to confirm whether they can be received normally, such as hello, thank you, goodbye, etc. If you can receive it normally, it means that the short message you sent before may contain sensitive words, so I suggest you avoid sending sensitive words.

2. Please confirm whether the fixed dialing service has been started.

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, please cancel the fixed dialing service.

You can enter the settings in the upper right corner of dial-up or telephone, and click Card 1 or more under Card 2 Fixed Dialing to turn off fixed dialing (you need to consult the operator about the PIN2 code required in the closing process).

3. If you are sending short messages in groups, it is recommended that you keep your mobile phone turned on or charged when sending short messages in groups.

4. If you can't send a short message to a short number (such as 1066), please go to Settings, search for the permission of paid SMS, and click Enter to find this information. It is suggested to set it as inquiry.

Third, all short messages can't be sent.

1. If your mobile phone is currently using a 5G network, it is recommended that you pull down the shortcut switch panel to turn off the 5G switch and try again.

2. Third-party SMS may have compatibility problems. Please enter the settings, search and enter the default application, and set the information as the system default.

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

4. If the SIM card is currently enabled with VoLTE, please enter the settings, search for VoLTE, turn off the VoLTE HD call switch and try again; If you can't find the VoLTE switch or turn it on again, the problem is still unresolved. It is recommended that you contact the operator to turn on the VoLTE function again, and then restart the equipment to try.

5. If a "red exclamation mark" appears directly when sending a short message, please hold down the message of sending failure and select more. Check the details, contact the operator and feedback the error code.

6. Please check whether the number setting of the SMS center is normal:

(1) Please enter the settings in the upper right corner of the message, and then click Advanced to set the correct SMS center number in the SMS center (there is no SMS center for telecom cards). If you don't know the SMS center number, please contact the operator to get the SMS center number and set it.

(2) If the confirmation number is correct, but the setting fails, it is recommended that you set up a SIM card on other devices. If the setting still fails, it may be a SIM card problem. It is recommended that you bring your valid certificate to the operator's business hall to replace your SIM card.

7. Please insert the SIM card into another mobile phone for investigation. If other mobile phones can't be sent, I suggest you consult the operator.

4. If the above troubleshooting fails to solve your problem, it is recommended that you clean up and restore the data.

1. Restore the information to the default settings.

EMUI: Information Three Points Settings, select the following to restore the default settings.

HarmonyOS System: Four Points of Information; Settings "four points, select the following to restore the default settings.

2. Delete data and cached information (SMS will not be deleted)

4. Before restoring the factory settings, please back up important data (QQ, WeChat and other third-party applications need to be backed up separately).
