can i purchase an iPhone 17 without selecting a carrier?

Yes. But you need to choose the "Buy" option first and then the "Connect to any carrier later" option, rather than the Finance or Apple iPhone Upgrade option.

Financed options require the selection of a supported carrier, and the existence of an active service line with the selected carrier.

The choices when I check out do not have xfinity. So how do I buy a phone.

You do what I showed in my previous reply.

Xfinity is not a supported carrier for financing, as such it is not an option.

You choose the "Connect to any carrier" later and then setup your service with Xfinity once you get the phone.

You do what I suggested and what Phil0124 showed. You have to buy the phone upfront, then you can choose any carrier you want after you get the phone as long as they support iPhone.

Ja, ohne Problem. Später einen Anbieter auswählen und auf das Gerät registrieren.

When you go through the steps to preorder an iPhone 17 the options are choose a carrier or select a carrier after purchase.

In some countries like my own - UK - carrier locking has been outlawed for some years anyway.
