After you receive the card, if it is not activated, there is no charge and there is no time limit for activation. However, it is recommended not to delay too long, because the banking system will automatically update within the specified time, and the update time of each bank and each bank's respective card type is inconsistent. No one can say for sure. If so, I suggest you open a card. If you don't want it, you can cancel it at the card bank to avoid unnecessary trouble.
