I ordered exactly that (unlocked US version) but got a single sim version. Was this a mistake in the order department or was your article misinformed? Ref: https://www.androidcentral.com/does-galaxy-s10-support-dual-sim
The US model is single-SIM. The international version comes in dual SIM. But the international version isn't guaranteed to work with all US carriers. (And there's no US warranty.)
