Renai Education can't issue the verification code, which may be a software problem. It is recommended to uninstall the software and try downloading again.

The mobile phone cannot receive the verification code for the following reasons:

1, mobile phone settings. Please check your phone settings, because it comes with an interceptor or an application you downloaded yourself.

2. Incorrect input of receiving number.

3. If only the short message with verification code cannot be received, other short messages can still be received. You can contact the product service provider that issued the verification code for feedback.

4. If it still can't be solved, you can contact the customer service of the number operation for help.
