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 click in Info >; Three o'clock > Settings > Advanced > 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 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 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.

If your phone can't receive SMS, you can do the following:
1. Unable to receive enhanced information.
If "enhanced information" is displayed in the SMS edit box, it means that the mobile phone is sending a short message with enhanced information. If you cannot receive the enhanced information, you can do so in the following ways:
1. After the enhanced information is sent, the other party cannot receive it.
Your message or number may be controlled by China Mobile's security policy, and China Mobile did not send it to the receiving end after receiving the message. For details, please call mobile customer service 10086 to confirm the cause of the problem.
2. The enhanced information is logged in for the first time, and the content of the received information has nothing to do with the enhanced information service.
There are still some defects in the background information push function of enhanced information, so after the first login of enhanced information, the information pushed by China Mobile is wrong. You can call 10086 to check the correctness of the push information.
3. Enhance information message display garbled code
(1) Enhanced information not supported by the receiver's mobile phone.
Warm reminder: If the text content is sent, it will be sent to the receiver by SMS; If you send a picture, a link will be sent to the recipient.
(2) Some message types (such as cards and public accounts) forwarding enhanced information will display garbled codes on the mobile phone. Due to the lack of the function of China Mobile Enhanced Information Server, the message you received is garbled. You can call 10086 to check the message garbled.
4. Increase information costs
The sender sends a message through enhanced information (enhanced information status: the background color of the sent information is blue). If the receiver is not in the enhanced information login state, the server will send a message to the receiver in the form of ordinary short message. This situation may result in expenses. Please call the operator's customer service hotline for details.
Warm reminder: To confirm whether the message is enhanced, you can check it through the information details. Steps to view information details: enter the information dialogue interface, press and hold the message to be confirmed > select more > more > view information details in the pop-up menu, and view the type in the information type. The type of enhanced information is chat information, and the other types are ordinary short multimedia messages.
If the message type that cannot be received is "General Message", please continue to check.
Second, some short messages can't be received.
For example, after sending short messages to operators (China Mobile/KOOC-0/0086, China Telecom/KOOC-0/0000, China Unicom/KOOC-0/00), can you successfully receive a reply? If there are, it means that some short messages can't be received by mobile phones.
1. Please check whether the number is saved in the privacy space.
You can enter the settings, search into the privacy space, open the information to see if you have received the SMS record. If yes, please move the required contact to the main space and try again. Operation method:
(1) In the privacy space, go to Settings >; Security and Privacy > Privacy Space, click Privacy Space to the main space;
(2) Select and check the files (such as contacts) to be transferred, click Move, and then complete the transfer according to the screen prompts.
2. Please check whether there is a blacklist in the harassment interception of mobile phone housekeeper.
Please delete the number from the blacklist if necessary, and then try:
EMUI 4。 X & 5.x & p8.x: mobile phone housekeeper > harassment interception > gear button > number blacklist;
EMUI 9.0: mobile phone housekeeper > harassment interception > interception rules > blacklist;
EMUI 9.0 . 1/9. 1/9. 1. 1/ 10。 X & ampEMUI 1 1。 X & HarmonyOS system: mobile housekeeper > harassment interception > gear button > blacklist or mobile housekeeper > harassment interception > interception rules > blacklist;

EMUI 10。 X & ampEMUI 1 1。 X: mobile phone housekeeper > harassment interception > SMS interception rules > intercepting strange SMS or mobile phone housekeeper > harassment interception > interception rules > SMS interception rules > intercepting all strangers.
4. Please check whether there is a third-party housekeeper application to intercept SMS.
Some security management applications will intelligently filter the received short messages, so it is recommended to uninstall this application. These applications are generally named after "XX housekeeper" or "XX assistant".
Please check if you just can't get the text message from Apple's mobile phone.
If you just can't receive the SMS from Apple's mobile phone, you can receive the messages from other mobile phones. It may be because your mobile phone number was bound to an Apple device before, and the other party sent you an iMessage instead of an ordinary SMS. Please refer to Apple's official instructions to unbind the phone number from the iPhone device. The specific steps are subject to Apple's official instructions.
6. Please check whether the short message contains sensitive words, which makes the mobile phone unable to receive it.
Please use the test message to check whether it can be received normally, such as hello, thank you, goodbye. Please avoid sending sensitive words if you can receive them normally.
Third, all short messages can't be received.
1. Third-party SMS may have compatibility problems. Please check whether you have used a third-party SMS application. If so, go to Settings, search for the default application, and set the information as the system default.
You can pull down the status bar, switch the flight mode 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 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.
4. please go to settings > system and update > developer options > turn off the "don't keep alive" switch in the application and set the "background process limit" to "standard limit".
5. Insert the SIM card into another mobile phone for troubleshooting. If other mobile phones can't receive it, 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.

Enter Settings, search and restore network settings, click Restore Network Settings (WLAN, Bluetooth and other related data will be deleted), and then try whether you can receive 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.

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 your mobile phone can't make calls, you can use the following methods:
1. You can't make phone calls in certain scenarios.
(1) Unable to dial someone's number, indicating that the user is busy.
Maybe the other party has blacklisted your number. I suggest you try to contact the other party in other ways, and you can dial normally after removing the blacklist.
(2) The short number cannot be dialed, and the prompt number does not exist.
It may be that the cornet is beyond the specified use area. The cornet is for local use only. If the cornet cannot be used outside the designated area, it is recommended to dial ordinary 1 1 digits.
2. You can't make a phone call unless it's a specific scene.
(1) Please confirm that the mobile phone card signal is normal.
When the status bar of the mobile phone shows emergency call only or "×" symbol, it will lead to the inability to make a call.
Warm reminder: If the mobile phone card signal is normal, you can't make a call, and you will be prompted that the number is empty or turned off. Generally, it is a network problem of local operators. I suggest you contact the local operator.
(2) Please ensure that call barring business is not opened.
Some operators' calling cards have call barring service. If your calling card restricts outgoing calls, some or all calls will be restricted. Please consult the operator's customer service for details.
(3) Please enable the VoLTE function.
It is possible that the 2/3G call network environment in your location is not good, so I suggest you try to turn on the VoLTE function. When the VoLTE function is turned on, the HD icon will be displayed in the signal bar.
If your mobile phone card doesn't have the VoLTE function, or your mobile phone doesn't support the operator's VoLTE function, please pay attention to whether the status bar of your mobile phone can be switched to 2G or 3G normally when dialing. If you can't switch, it may be caused by insufficient coverage of 2G/3G networks in this area. I suggest you try calling from another place.
(4) Please restore the network settings.
It is recommended that you search in Settings to restore network settings and try to restore network settings.
Tips: Restoring the network settings will delete the WLAN and Bluetooth connection records, and you need to enter the screen lock password for verification.
If your mobile phone still can't make a call, I suggest you contact Huawei's customer service hotline (950800), or back up the information in advance (third-party applications such as QQ and WeChat need to be backed up separately), and bring relevant purchase vouchers to the nearby Huawei customer service center for testing.
