Samsung Galaxy S21 Ultra 5GGray 12GB RAM + 128GB

The Samsung Galaxy S21 Ultra 5G is aimed at users who want the most advanced camera and display Samsung offered in the S21 generation, without compromising on performance or battery life. Its 6.8‑inch Edge Dynamic AMOLED 2X Infinity‑O display delivers QHD+ resolution (up to 3,200 × 1,440 px), an adaptive 10–120 Hz refresh rate and HDR10+ support, giving you extremely sharp, fluid and bright visuals for gaming, streaming and productivity. Gorilla Glass Victus on both front and back, a solid aluminium frame and the subtly curved screen edges combine to create a premium feel, while the large canvas is still comfortable for two‑handed use. Choosing a certified refurbished Galaxy S21 Ultra 5G from Remobile lets you enjoy this top‑tier hardware at a fraction of the original price while reducing CO₂ emissions and electronic waste.

Power for demanding users and 5G

The Galaxy S21 Ultra 5G is powered by Samsung’s Exynos 2100 or Qualcomm’s Snapdragon 888 5G chipset (region dependent), both built on a 5 nm process for high performance and improved efficiency. Paired with 12 GB or 16 GB of RAM and internal UFS 3.1 storage options of 128 GB, 256 GB or 512 GB (without microSD expansion), it handles heavy multitasking, photo and video editing, and graphics‑intensive games with ease. The phone launched with Android 11 and One UI 3.1 and has since received multiple major updates, benefiting from Samsung’s extended OS and security update policy so that refurbished units continue to feel current and secure in 2026. With full 5G support, Wi‑Fi 6E, Bluetooth 5.2, NFC and USB‑C 3.2, the S21 Ultra offers fast and stable connections for networks, accessories and peripherals.
