1. Submit more financial proof: If you can provide information such as real estate certificate, automobile property certificate, income certificate or professional qualification certificate, the bank will consider the applicant's strong repayment ability and upgrade the card level.
2. Increase the frequency of consumption: you can't submit proof of financial resources, but only let the bank judge the repayment ability of users through usage. Increase the frequency and amount of consumption, so that banks will think that the current card level can no longer meet the needs of users, thus improving the card level.
3. Repay each installment on time: don't overdue the credit card during use. As long as there is overdue, banks will be more strict when upgrading their cards. Repayment on time in each installment can prove that cardholders are willing to repay and have good repayment habits, and banks are more willing to upgrade the card level for such users.
