Note: I've noticed more recently that when you confirm the new card with your credit card company, the card may well update on your phone with you having to do little more than confirm the CVV code on your phone. If the card number is totally new, it can often be easier to simply delete the card from the phone and enter the card as a new payment method on your phone.
