You can do it most of the time, but it is recommended not to call the customer service hotline to open a card in the middle of the night and early in the morning. Banks usually do system maintenance during this time period. If you encounter this, you will not be able to open it and you have to wait. Only if the system is well maintained.

In addition to the customer service hotline to open a card, you can also go to the financial management counters of CCB branches to open a card. If you have a CCB online banking shield, you can also open a card after logging in to online banking.
