Bank of China sent me a text message saying that I raised the amount, but I didn't apply for a credit card from Bank of China.

There are several ways to increase the quota:

1. Temporary limit adjustment. When using a bank credit card, if you find that the approved credit limit is not enough and need to increase the credit card limit, you can call the 24-hour customer service hotline to contact the customer service specialist and apply for a temporary increase in the credit card limit. After the expiration of the validity period of the temporary adjustment of the bank credit card limit, the credit limit will be automatically restored to the original limit;

2. Long-term credit line adjustment. If the credit card limit of the bank is insufficient, you can call the 24-hour customer service hotline at any time to apply for a permanent increase in the credit limit. The bank will review your past credit card usage records and repayment records, and adjust the credit card limit appropriately for the cardholder after approval.

3. The validity period of the temporary credit line is 1 month at the longest, and it will be automatically restored to the credit line before adjustment. Please ensure that the account balance does not exceed the original credit line before the current billing date, or you will have to pay the over-limit fee.
