Because 1 U.S. dollar can be exchanged for about 6 yuan of RMB, the credit limit of a U.S. dollar account is calculated based on 1:6.
If the limits of the original card and the new card are both 5,000 yuan, then the U.S. dollar limit is based on 1:6, that is, the U.S. dollar limit of 5,000/6=833. If the previous card is still 714 yuan, you can call the customer service hotline and change it to 833.
However, it should be noted that the available quota will change according to the daily exchange rate, so converted from the exchange rate on the day of the screenshot, the available USD quota is 815. This actually has no impact, as long as it is within the available limit, you can use it.
