What should I do if my mobile phone can't receive SMS? ?

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

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 with the operator whether the "High Frequency/Advanced Disturbance Interception Function" is enabled, which will intercept some short messages.

2. 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 so,

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.

3. Please check whether there is a blacklist in the harassment interception of mobile phone housekeeper/tablet housekeeper.

Please remove the number from the blacklist as needed and try: enter the mobile phone housekeeper/tablet housekeeper > harassment interception > interception rules > blacklist.

4. Please check whether intercepting strange short messages is set in the harassment interception of mobile phone housekeeper/tablet housekeeper.

Please turn off this switch as needed and try (taking mobile phone housekeeper as an example): go to mobile phone housekeeper > harassment interception > SMS interception rules > intercept strange SMS.

5. 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".

6. if you can find the intercepted messages during the period of entering mobile phone housekeeper > harassment interception, please check the message types, advertising messages, spam messages, etc. If it is a normal SMS intercepted by mistake, please contact Huawei customer service hotline 950800 for more help.

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 restarting the VoLTE switch, it is recommended that you contact the operator to restart the VoLTE function and try again.

4. please go to settings > system and update > developer options > turn off the 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.

1. Restore all settings of information.

EMUI: information > three points > settings > three points, and select the following to restore the default settings.

HarmonyOS system: information > four points >; Settings > 4 o'clock, select the following to restore the default settings.

2. Restore network settings

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.

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