If you do not receive the confirmation code, please check the following two items.
Whether the phone number is correct
Whether the communication environment is unstable
If you issue the authentication code multiple times, it will be limited (locked) and an error message 'This phone number has been used many times' will be displayed.
If it is locked, it will be unlocked after 24 hours, so please start over from issuing the authentication code.
If you still cannot receive the authentication code, please contact your mobile service provider.
※We regret to inform you that we cannot provide support for this issue even if you contact with support.
