Generally, the credit card of Bank of Communications can exceed the cardholder's credit card limit at most 10%. If the cardholder's credit limit is 10000 yuan, then he can exceed the consumption by 1000 yuan at most. However, the specific amount of excess consumption will be determined by Bank of Communications according to the cardholder's card usage and credit status.

At present, Bank of Communications doesn't charge credit card over-limit fees, but in a billing cycle, Bank of Communications only provides credit card over-limit consumption once. After the cardholder overuses it, Bank of Communications will send a short message to inform him. If you want to continue to use the card, you can only repay the loan as soon as possible to restore the limit.
