Did CCB invite Platinum Card by SMS?

You should mean that CCB sends a text message inviting you to upgrade your platinum card. Well, under normal circumstances, banks invite high-quality customers to upgrade their platinum cards, and only those who meet the requirements will be invited, so in this case, it can basically be approved, even if it is not approved, it should be only a special case. As far as I know, it will take about 30 days if I accept the invitation to reply to the message. If you have replied, you can log on to the credit card website of CCB, click "Application Progress Query", enter your ID number and check the application progress. If this cartoon passes, the bank will give you a business card to print and send you a text message telling you the mailing number. Pay attention to the text message yourself.
