Supplies of iPhone XR units were pretty slim early on and as usual Apple chose to prioritize carriers in the US. The SIM free option just went live on Apples site, so if you havent jumped on T-Mobiles free XR offer, you can go skip the new contract.
Youll have to pay the full price up front thats $750 for the 64GB model, $800 for 128GB and $900 for 256GB. Delivery is listed as 1 business day, so an online order should arrive pretty quickly. Or you could pick one up from Apples retail stores.
There are still no official cases for the iPhone XR, Apple is just selling a couple of OtterBox cases.
