Yes, please look at the customer service hotline printed on the back of the credit card, which shows that it is 24 hours. When you make a phone call, you can open the card through self-service voice and enter the card and ID information. It's better to dial with the reserved mobile phone, which is very convenient. Besides customer service hotline, outlets and online banking, cards can be opened now, but the security requirements of online banking are relatively high, so you need to apply for an online banking shield, otherwise you can only open cards, and you can't set passwords.
