What if I can't send a text message?

If you use a Huawei mobile phone, you can do it in the following ways:

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 send the information by ordinary SMS, so that you can contact the other party in time.

3. If it still hasn't been solved, I suggest 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 sentences 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.

Please confirm whether the fixed dialing service has been started.

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, please cancel the fixed dialing service.

You can go to the settings in the upper right corner of the dial-up or telephone, and click Card 1 above under Card 2 > Fixed Dialing > Turn off Fixed Dialing (you need to consult the operator for the PIN2 code required during the turn-off process).

3. If it is a mass message, please confirm whether the screen is closed during sending. It is suggested that when you send short messages in groups, the screen of your mobile phone is on or always charged.

4. If you can't send short messages to short numbers (e.g. 1066), please go to Settings, search the permission of paid SMS, and click Enter to find 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, I suggest you pull down the quick switch panel and turn off the 5G switch and try again.

2. Third-party SMS may have compatibility problems. Please check whether you use a third-party SMS application. Check method: Please enter Settings, search to enter the default application, and check whether the application selected in the information is a tripartite SMS application. If yes, please set the system default information as the system default.

You can switch the flight mode, 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 the VoLTE switch is not found or the problem is not solved after the VoLTE switch is turned on again, it is recommended that you contact the operator to turn on the VoLTE function again, and then restart the phone to try.

5. if a "red exclamation mark" appears directly when sending a short message, please press and hold the message of sending failure, select more > view information details, contact the operator and feed back 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 click Advanced > Set the correct SMS center number in the SMS center (there is no SMS center in the telecom card). 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 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 5。 X/8。 X: information >; More > settings > restore default settings.

emui 9 . x/ 10 . x/ 1 1 . x:information >； At three o'clock > Settings > Three o'clock, select the following to restore the default settings.

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

Enter settings, search application management, find information, and click Save >; Delete data.

3. Restore network settings

Go to Settings, search to restore network settings, click Restore Network Settings (WLAN, Bluetooth and other related data will be deleted), and then try to send SMS.

Warm reminder: This operation will not delete data or files, but only restore the settings of WLAN, mobile data network and Bluetooth (such as hotspot connection information and Bluetooth pairing information), and other mobile phone settings will not be restored.

4. Please back up important data before restoring factory settings (third-party applications such as QQ and WeChat need to be backed up separately).

Enter settings, search for factory settings, and then click Restore Factory Settings.

Warm reminder: This operation will delete all data in your storage device, including account, system and application data and settings, installed applications, music, pictures and all files in the internal storage space.

If the problem still exists, please back up the data (QQ, WeChat and other third-party applications need to be backed up separately) and then take the purchase voucher to Huawei customer service center for testing and processing.
