Welcome to the community!
I'm doubtful that any of the mobile providers will carry the device in their line-up. It's such a niche device that it doesn't make sense for them to carry inventory for it. The price tag of $2599 is prohibitive for most customers. Even with an XXXL plan, the upfront costs would still be out of reach for the vast majority of customers. The devices providers usually carry are accessible for the majority of their customer base. As far as I am aware, the device will be available at the Samsung Experience stores across the Country (see here).
Hope this helps 😀
