You would need to return the iPhone 17 Pro within your 14-day period if you purchased online or over the phone, and once this has been received and processed as a return you would then be able to order a 17 Pro Max. If you purchased this in-store, the 14-day change-of-mind does not apply and there is no return policy.
The 17 Pro Max is currently experiencing stock shortages, with wait times on orders placed today being "expect dispatch within 21 days" for the Blue and Silver and "expect dispatch in more than 28 days" for the Orange with the standard storage.
