After the credit card credit approval process is initiated, send supplementary SMS at most several times.

After the credit card credit approval process is initiated, the supplementary SMS will be sent at most 3 times. The reason is to remind applicants to provide the required information as soon as possible to speed up the approval process. Sending SMS for up to three times after the credit card credit investigation and approval is initiated can avoid excessive SMS harassment, and it is also a management measure to ensure the efficiency of the approval process and the applicant's active cooperation, which is helpful to reduce the approval delay caused by the applicant's negligence or delay.
