There are generally three ways to activate credit cards, namely SMS activation, online activation and customer service telephone activation. SMS activation and phone activation have detailed steps in mailing registered letters of credit cards.

The steps or details of SMS activation and online activation are a bit cumbersome and troublesome. The most common and convenient method is to activate the customer service phone. There is a bank's credit card customer service line on the back of the credit card, which is generally a 24-hour customer service hotline at the beginning of 400. After activation, just call customer service and enter relevant information according to the voice prompt.
