Tell you a common sense, the credit card limit of the same bank is not cumulative. For example, if two Bank of Communications cards are held by the same person, and the limits are 10000 and 5000 respectively, then the combined use limit of these two cards is 10000, because one person is an account, not a card. Then, the credit card limit itself is not counted and can only be approved by the Shanghai Bank of Communications Credit Card Center. If you want a larger amount, try to provide proof of property such as real estate license in my name.
