Description
Samsung Galaxy S21 Ultra G998U1 128GB in Phantom Black — Wholesale C/D Stock
Built for enterprise, healthcare, and government device programs, the Samsung Galaxy S21 Ultra launched in January 2021 with a 6.8-inch QHD+ 120Hz Dynamic AMOLED 2X display, the Snapdragon 888 5G chip, 12GB of RAM and a quad rear camera led by a 108MP main sensor with 3x and 10x telephotos. Power comes from a 5,000mAh Li-Ion battery with 25W wired charging. It is rated IP68 (immersible up to 1.5 m for 30 minutes). It runs Android 11 with One UI 3.1 at launch, upgradable to Android 14 (manufacturer OS updates have ended). The device measures 165.1 x 75.6 x 8.9 mm (6.50 x 2.98 x 0.35 in) and weighs 227 g (8.01 oz). This lot is the G998U1 in the 128GB configuration, Phantom Black, unlocked and graded C/D Stock.
The Galaxy S21 Ultra 5G is past its manufacturer OS update window, so it suits single-purpose, kiosk, testing, and budget roles rather than long-horizon deployments. Consistent hardware across the lot simplifies imaging, accessory standardization, and support for refresh programs and field teams. An IP68 rating supports rollout to warehouse, field, and healthcare settings where dust or moisture exposure is expected.
