1. Bring your ID card and credit card to the counter of the issuing bank for activation.

2. Activate online by calling the service hotline of the issuing bank. During the activation process, you need to send SMS for identity verification, and you need to ensure that the reserved mobile phone number can receive SMS normally.

3. In addition, the cardholder can activate the credit card according to some designated channels of the issuing bank, such as online banking and mobile banking. After the credit card expires, it can't be used. About one month before the expiration, the issuing bank will take the initiative to confirm whether to change the card. If it is changed, it will mail the new card to the cardholder's address, and the cardholder will activate it after getting the new card.
