If you have subscribed for MMS billing, your mobile phone will receive the MMS bill about 3 working days after the billing date. There are only MMS bills before the repayment due date. However, if the repayment is not repaid after the due date, CCB will send a text message to remind you. Because CCB credit card has a 5-day grace period, it is completely time to repay immediately when you receive the text message reminder, and it will not affect your credit record. , no additional charges will be incurred.
