Your available limit needs to reach 3500. If your current limit is below 3500, you can call customer service and ask for an increase in the temporary limit, which can generally be increased by about 50%. For example, your credit card limit is 2000, which can be temporarily increased to 3000.

Staging means that after you buy something, call the customer service and he will help you with it.

If you don't call customer service, you can only wait for the bank to automatically increase the limit according to your credit history and credit card swiping. Generally, some banks will automatically increase your quota after you apply for a card for half a year. My boyfriend has a Zhang Zhongxin card, which has been useless. After a year's investigation, the limit was raised from 6000 to 19000, and then he went to cancel the card. The customer service said that as long as the card was not cancelled, the limit could be increased, but it was really useless and it was cancelled.

There's another way. For example, if your quota is 3000, you can deposit 500 in the card first, and then your available quota will become 3500. There is no need to call the customer service hotline.

But instead of waiting for the bank to increase your quota, it is better to apply for a credit card at another bank.
