My mobile card can't be displayed by SMS in Xiaomi Mobile 1S Youth Edition, and I can't get the SMS center number.

Can you get the message? When did the problem arise? It is recommended that you try the following methods:

1, set the number of SMS centers, and set the number of SMS centers in SMS interface-menu key-Settings-Advanced Settings. For example, +86 1380000000

2. If you still can't send SMS, take off the mobile phone card, insert it into another mobile phone and set the SMS center number, and then insert the SIM card back into the mobile phone.

3. Whether optimization software such as power saving, optimization, assistant and forced task termination is installed to guide users to close or uninstall attempts.

4. If it still can't be solved, you can try to refresh the computer with Miflash after the backup. After the refresh, you can try to send the information without restoring any backup.

Thank you for your support and wish you a happy life!
