There are generally three ways to activate credit cards: SMS activation, online activation and customer service phone activation. SMS and phone activation are detailed in the registered letter to send you a credit card.
SMS activation and online activation may not be easy to handle, and the steps or details are a bit cumbersome.
One of the most common and convenient is the activation of customer service phone. There is a 24-hour customer service hotline starting with 400 on the back of the credit card. Call customer service and enter relevant information according to the voice prompt.
