Thank you for pointing this out, we'll get it fixed. The error probably happened because dual eSIM works, but not physically.

Here is another link to information from Apple: https://support.apple.com/de-ch/118669

The product is new as there is no indication that it is a refurbished model. The product information refers to a new device with the stated specifications.

Good evening, you can use the trade-in under the same conditions as on the Apple website. Even with better conditions.
