generally, a credit card is valid for 3 years, and each bank card is different. Minsheng Bank's credit card has not been activated for a long time and can only be activated by calling the customer service hotline. The customer service will send an appointment activation code to your reserved mobile phone, and just reply by SMS. At the same time, if the activation is unsuccessful after repeated replies, you can only take the credit card and ID card to the local sub-center for activation.
if you have any other specific questions, I suggest you call the customer service staff of the bank, hoping to help you.
