The counseling account can be changed to a bound mobile phone, but no one can log in, and the background will prompt you to change your mobile phone to punch in.
If the mobile phone is lost, you need to log in to a new device and change the bound mobile phone number. If the previous account has been enabled for account security protection, you need SMS verification code when logging in. The old mobile phone number is lost, so you can't log in by SMS. It is suggested that you can reissue your mobile phone number or re-register with a new mobile phone number.
