Can I pre order iphone for a friend?

Online orders must ship to an address within the online store country.

The payment method must have a billing address within the country of purchase.

If you buy an item from the US store, credit card has to be from the US.

that is Apple’s policy.

No, you can't. Apple doesn't ship internationally.

Doesn't matter. You cannot order a phone from Pakistan to be delivered to the US. No way. No how.

I see Johnathan gave you an acceptable answer.

If you want to buy a phone for a friend in the US. Send them the money and let them buy the phone themselves in the US.
