CCB's credit card bills are provided by paper bills (printed by surface mail), electronic bills (electronic bills sent to EMAIL), short message bills (short messages sent to mobile phones), and multimedia message bills, which are sent to mobile phones in the form of multimedia messages, with repayment amount, repayment time and bill details. Do you see if you have received the bills? There is also the possibility that CCB will send marketing activities in MMS format. There is a big difference between these two short messages, so the landlord should judge ~ In addition, the customer service hotline is engraved on the back of the credit card, starting with 4, so you can have a look. You can also edit the last four digits of the short message CCYH# card number and send it to 95533 to inquire about the repayment amount, which is real-time.
