The reason I ask is because while the Sim-Free version of the iPhone XS Max is what I wanted, when I did the AIUP pre-approval process it asked for my phone and carrier (T-Mobile). I reckon if I choose the wrong carrier, it wouldn't have allowed me to proceed. But now after ordering my phone, it doesn't make a carrier distinction in my email or when I review my process pending page. So I'm wondering if I got T-Mobile, or the Sim-Free version, or (which I guess is what happened) things are still processing so the page I'm viewing doesn't have my carrier information.
