The credit card limit of ICBC is really low. If you want to increase the credit limit, you should always swipe your card, and then repay it on schedule, and keep a good credit card record (no arrears). You can call the credit card customer service hotline every six months to one year to increase the quota. It is difficult to judge the specific increase, and the credit card center will comprehensively evaluate it (there are many factors, such as your income, company situation, consumption situation, etc. ).
