What is the reason why the mobile phone can't receive SMS?

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

1. Some messages cannot 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 there is a blacklist in the mobile housekeeper harassment interception.

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

2. Please check whether intercepting strange short messages is set in the harassment interception of mobile phone 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.

3. 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".

4. 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:

A. in the privacy space, enter Settings >；; Privacy >; Privacy space, click the privacy space to the main space;

B select and check the files to be transferred (such as contacts), click migrate, and then complete the transfer according to the on-screen prompts.

5. Please check with the operator whether to turn on the "high frequency/advanced harassment interception function", which will intercept some short messages.

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.

Second, I can't get any short messages.

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. 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.

Warm reminder: How to open the developer option:

Open the settings, enter about mobile phone in the search box, and click to enter the page about mobile phone; Click the EMUI version number or HarmonyOS system version number 7 times continuously and quickly until a prompt appears, prompting you to be in developer mode!

4. Please insert the SIM card into another mobile phone for investigation:

① If other equipment cannot receive it, it is recommended that you consult the corresponding operator for processing.

② If other devices can also receive it, it may be that the VoLTE network is abnormal. It is recommended that you contact the operator to re-enable the VoLTE function and try again.

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

1. Default settings for recovery information:

path 1:Info >； Three o'clock > Settings > Three o'clock, and select Restore Default Settings below.

Path 2: information >; Four o'clock >; 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.

Note: 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). ), other settings will not be restored.
