credit card (debit card) handles bill installment, which shows that the balance is insufficient because the user needs to reserve enough available balance for the bank to deduct the handling fee. When the available balance of credit card (credit card) is insufficient, a reminder of insufficient balance will appear when the bill installment is selected. At this time, the user can repay part of the arrears in advance, restore part of the credit card (debit card) line, and then apply for bill installment.

in addition, the bill can't be paid in full by installment, and some amounts don't participate in installment, so users must pay this amount in full when repaying.
