1. Credit card installment can be repaid in advance, but you need to contact customer service in advance to terminate the installment. If you don't apply for termination of installment, the remaining installment amount will not be billed at one time, and it will still occupy the card amount, and the money you deposit is only equivalent to the deposit.

2. In addition, even if the installment is terminated in advance, the handling fee for the remaining installments will still be charged. For example, if you pay 1 yuan for each issue and 12 yuan for each issue, the bank will only think that you have overpaid, and the rest is just overpayment. The bill is still deducted in one installment. If you can, you can cancel the installment payment first, then pay back, and click on the repayment directly, but the details still depend on the bank's regulations. Of course, some banks are more humanized, and the remaining installments can be repaid in advance without handling fees.
