There is an error in the quick SMS service of China UnionPay.

China UnionPay Express failed to obtain user information, and China UnionPay Express failed to display bank verification code information. The first possibility is that you entered the wrong verification code, which is basically the case. The second possibility is that the verification code input exceeds the specified input time, and the verification information of the short message cannot pass. This situation may be due to the data exchange time between China UnionPay Express and the bank, or it may be that the customer himself has delayed the time.
