Three months before the card expires, we will remind you through relevant channels that your card is about to expire. If you don't call to make it clear that you don't need a new card, we will mail you a new card within 2 months before it expires. The new card can be used after it is activated. The card number and password remain unchanged. To prevent risks, please destroy the magnetic stripe and chip of the old card after activating the new card. If the new card fails to be made because the card is not used for a long time, you can call the credit card customer service hotline 4006695599 to manually change the card.
