Questions about Apple iPhone 14 Pro Max

Why did I pre-order it a week ago anyway? Until last night it said 'delivery expected tomorrow' and now suddenly mid-October??? I am really disappointed.

Comes with its original box?

Is this working with a vodafone network sim card from another country? Or only working with a Switzerland network sim card?

If you order it today, can you still assume that it will be delivered at the end of October~ / the delivery date is correct? Is it possible to order a large enough quantity from the supplier to satisfy the demand? Thank you very much in advance!
