Apple's mobile phone information has not been seen, but it has not been opened.

When Apple's mobile phone displays unread information, but it doesn't, there may be the following reasons and solutions:

1. Turn on the "read-only" function: You can try to enter the phone setting interface, find the SMS option, and see if the "read-only" function is turned on. If this function is turned on, all messages will be automatically marked as read, and unread messages cannot be viewed.

2. SMS application settings: You can try to enter the phone settings interface, find the SMS option, and see if the "read-only" function is turned on. If this function is turned on, all messages will be automatically marked as read, and unread messages cannot be viewed.

3. There are too many spam messages or harassing messages: You can try to clean up the SMS records, delete irrelevant information and reduce interference.

4. Set the function of filtering spam messages and unknown senders: enter the setting menu of the mobile phone, and find the option of "Information" or "SMS" to see if the function of filtering spam messages and unknown senders is turned on. If so, please disable these filtering settings.

5. Update the software: Make sure your Apple phone is running the latest version of the operating system.

6. Reset SMS settings: In the settings menu of the mobile phone, select General-Restore-Restore all settings. This will restore the mobile phone settings to the factory default values. Please note that this operation will not delete your data, but will reset some system settings.
