What should I do if the verification code of red rice mobile phone short message can't be opened?

Check whether the mobile phone has downloaded third-party software, such as security guards. It is possible that the software intercepted the short message, so it is recommended to uninstall it. Verify whether the SMS blacklist function is set in the mobile phone. Check the mobile phone notification settings, whether SMS notification is turned on, and whether the notification method is the setting window. If all these methods are useless, it is recommended to save data backup and restore factory settings.
