Hi, yes, I tried to get a SIM-Free version. Also, I have read things there on that page you linked many times already. The thing is, even before I applied for the Apple card, I used to be able to still see that financing/installment option (by CitizensOne) already by selecting a carrier for an iPhone, so why would anyone need to get an Apple Card in order to get Monthly Instalments Option?
I just tried checking out as guest (which means there is no credit card (No Apple Card) information on the checkout page) but I was still be able to finance it through Citizens One (Not by using an Apple Card as payment) by selecting an iPhone with a Carrier. So it seems that we don't need an Apple Card at all for Monthly Instalments (?):

That, again, begs the question: why would anyone need to get Apple Card in order to get the Monthly Instalments Option, if it is there already as long as we get an iPhone with a phone carrier?
In addition, the following option is what I don't see (but expect to see) during checkout (I have tried both website and the Apple Store App):
