The iPhone 16 Plus in 512GB Ultramarine (model A3290) is Apple's larger-screen standard-tier phone from the prior generation, sitting below the Pro models but offering a bigger 6.7" display and battery than the base-size iPhone 16 in the same non-Pro camera/chassis tier. Ultramarine is one of the iPhone 16 line's launch colourways. 512GB is the largest storage option offered for this model, aimed at users with large media libraries, extensive offline app/game storage needs, or heavy photo/video shooters who don't want to manage storage or rely on iCloud. It's a good fit for buyers who want a big screen and generous storage without paying for Pro-tier camera hardware.
