Why don't I often get SMS reminders from the 5 million lottery network? Is it a system problem?

If you use a Huawei mobile phone, you can use the following methods: 1. Unable to receive enhanced information. The "enhanced information" displayed in the edit box indicates that the mobile phone is sending short messages with enhanced information. If you can't receive the enhanced information, you can do it in the following ways: 1. After the enhanced information is sent, the other party can't receive your message or the number may be controlled by China Mobile's security policy, and China Mobile didn't 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. The enhanced information message displays garbled (1) enhanced information that is 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. The sender of the enhanced information charge sends the message through the enhanced information (enhanced information status: the background color of the sent message 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 so, 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, enter 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 remove the number from the blacklist as needed and try: mobile phone housekeeper > harassment interception > gear button in the upper right corner/interception rule > blacklist. 3. Please check whether intercepting all strangers is set in the harassment interception of mobile phone housekeeper. Please turn off this switch as needed, and try: 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 that intercepts 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, 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, if hello, thank you, goodbye. Please avoid sending sensitive words if you can receive them normally. 3. 1 Unable to receive all short messages. 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 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. Four. If the above troubleshooting fails to solve your problem, it is recommended that you clean up and restore the data. 1. Restores all settings of information. EMUI: information >; At three o'clock > Settings > Three o'clock, select the following to restore the default settings of HarmonyOS system: Info >；; Four o'clock >; Settings > 4 o'clock, select the following to restore the default settings. 2. delete the data and cache of information (SMS will not be deleted), enter settings, search application management, find the information, and click save > delete data. 3. Restore Network Settings Enter Settings, search Restore Network Settings, click Restore Network Settings (this will delete WLAN, Bluetooth and other related data), 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. 4. Please back up important data (third-party applications such as QQ and WeChat need to be backed up separately), and then set it after restoring the factory settings. Search to restore the factory settings, and 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 bring the purchase voucher to Huawei customer service center for testing and processing.
