What if Huawei's mobile phone can't send text messages?

1. Enhanced information cannot send short messages. If "enhanced information" is displayed in the edit box, it means that the mobile phone is sending short messages 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 keys > settings > enhanced information). 2. If you need to contact the other party urgently, it is suggested that you turn off the enhanced information function first and send the information by ordinary SMS, so as to contact the other party in time. 3. If the other party cannot receive the enhanced information after you send it, your message or number may be controlled by the operator's security policy, and the operator did not send it to the receiver after receiving the message. For details, please call the operator customer service to confirm the cause of the problem. 4. 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 successful, it means that some short messages can't be sent by mobile phone. 1. If the short message contains sensitive words, the other party cannot receive it after sending it. Please send a short message with a test sentence to confirm whether it can be received normally, such as sending hello, thank you, goodbye, etc. If you can receive it normally, it means that the 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. After starting fixed dialing, 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 enter mobile phone >; Three-key > Settings > Card > More > Fixed Dial Close Fixed Dial (please consult the operator for the PIN2 code required during the closing process). 3. If you are sending a group short message, please confirm whether the screen is closed during sending. It is recommended that you keep your mobile phone screen bright or keep your mobile phone charged when sending group short messages. 4. If you can't send short messages to short numbers (such as 1066), please go to Settings, search for paid SMS permission, and click Enter to find information. It is recommended to set it as a query. 3. All short messages can't be sent. 1. You can try again after restarting the network by switching flight modes. 2. If your mobile phone is currently using a 5G network, I suggest you pull down the shortcut switch panel to turn off the 5G switch and try again. 3. 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 cannot be found or the problem is not solved after restarting the VoLTE switch, it is recommended that you contact the operator to restart the VoLTE function first, and then try to restart the mobile phone. 4. 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 selected information is a three-party SMS application. If yes, please set the system default information as the system default. 5. if the "red exclamation mark" appears directly when sending a short message, please press and hold the failed short message to select more > view the information details, contact the operator and feed back the error code. 6. Please check whether the number of the SMS center is set normally: (1) Please click Message > Three-Point Button > Settings > 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 another mobile phone. 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 inspection. If other mobile phones can't be sent, I suggest you consult the operator. 4. If the above troubleshooting can't solve your problem, I suggest you clear and restore the data. 1.
