Why can't the SMS be sent out after the Cool 7296 mobile phone is restored to factory settings?

It is recommended to restart the phone or restore the factory settings. Cool reference path: click Settings-System Settings-Reset the phone-Restore factory settings-Reset the phone, and then follow the prompts. If the mobile phone is logged into the LeTV account or the fingerprint/password unlock is set, it is necessary to log off or unlock the screen before resetting the mobile phone.
