At present, credit cards basically support minimum repayment or installment repayment. As for whether the bill of Shanghai Pudong Development Bank can be changed after installment, according to the regulations of Shanghai Pudong Development Bank, once the bill of Shanghai Pudong Development Bank is successfully handled, it cannot be revoked, nor can the installment amount and the number of installments be changed.

For the installment that has not happened, it can be cancelled in advance. You can call the Pudong Credit Card Service Hotline to apply for canceling the signing installment in advance. It is worth noting that if there is no interest-free credit card bill after installment, a part of the handling fee will be paid in addition to the principal every month. The specific rate is determined by the number of periods.
