Callback is not absolute, and it is related to the application materials and personal credit information provided by you. Banks will only spot-check some customers for a return visit, not all of them. The other is that when the card is approved, it may not be called back, but it may be notified by SMS. Generally, 95% of people who receive a return call can get off the card as long as they can answer the questions smoothly. Credit card telephone return visits generally enter the second trial stage. As long as the data verification is successfully completed, the card can basically be issued.
