If your statement is accurate:
“I pre-ordered the new iPhone Duo today using Apple Pay. However, I’ve just realised that I’ve lost my default payment card. Will I still receive my iPhone Duo on the estimated delivery date if I replace my payment card in Apple Wallet? The delivery date is in December, so I don’t expect Apple to charge me before my replacement card arrives.”
There are two possibilities to consider.
1. If your order has not been completed successfully
If Apple has not confirmed your order and provided you with an order number, it is possible that the payment authorisation is still pending or that the transaction has not been completed. In that case, you should check your order status and ensure that you have a valid payment method available. However, the absence of a charge does not necessarily mean that the order is incomplete, as Apple may process payments at a later stage.
2. If Apple has confirmed your order and provided an order number
If you have received an official order confirmation and an order number, it generally indicates that Apple has accepted your order. If Apple Pay successfully authorised the transaction when you placed the order, losing your physical card afterwards does not automatically invalidate that authorisation or cancel your order.
It is important to understand that a physical payment card and Apple Pay are not exactly the same thing. Apple Pay uses a device-specific payment token rather than simply transmitting your physical card details. Depending on your bank's policies and the action taken to report the card lost, Apple Pay transactions may continue to work, or the bank may suspend the associated digital payment credentials.
Therefore, losing your physical card does not necessarily mean that Apple Pay will stop working immediately.
However, once you report the card lost, your bank may disable the card and its associated Apple Pay credentials.
My conclusion: If Apple has confirmed your pre-order and provided an order number, you should not assume that your delivery will be affected merely because you lost your physical payment card. Nevertheless, if Apple needs to collect payment closer to the December delivery date, it may require you to update your payment method if the existing one is declined.
The safest approach is to check your order status on Apple's website and follow any payment-related instructions displayed there. An order confirmation is a good indication that your order has been accepted, but it does not guarantee that a future payment will succeed.
