enter the mobile phone number, the user will receive SMS verification code, but now the situation is a little strange, mobile users are normal, Unicom users will receive two verification codes (different), the interval is about 1 minute, the company tried several numbers, so kneel!

I think you may have sent it twice, because numbers in mainland China are usually sent through the same channel. Or did you only request once, but bug appeared on the side of the SMS provider, resulting in a resend to China Unicom
did you request the interface twice in a short period of time?
