Galaxy S21 256GB 5G Unlocked

The Samsung Galaxy S21 is a fully unlocked smartphone with 256GB of internal storage and 5G connectivity. It is intended for users who want a flagship-grade handset without carrier restrictions. The device ships in Phantom Gray and is sold as new inventory. Buyers who need dual-SIM capability or expandable storage should look elsewhere.

Dynamic AMOLED 2X 120Hz Display

The 6.2-inch Dynamic AMOLED 2X panel runs at 120Hz and supports HDR10+ with a peak brightness of 1300 nits. Sustained interaction such as gaming or video playback remains fluid thanks to the high refresh rate. The screen covers 94.1 cm² and achieves an 87.2% screen-to-body ratio. There is no mention of adaptive refresh behaviour under thermal load.

Glass Front Plastic Back Aluminium Frame

The handset measures 151.7 x 71.2 x 7.9 mm and weighs 169 g. Its construction uses Gorilla Glass Victus on the front, a plastic rear panel and an aluminium frame. The supplier notes that Grade C units may show dents, cracks, chips, scuffs, scratches or dark spots on the LCD. No thermal throttling data, fan noise figures or power-draw numbers are provided.

Questions about this item

How warm does the Exynos 2100 or Snapdragon 888 get during all-day use with the 120 Hz AMOLED screen?

The 4000 mAh battery and 7.9 mm chassis limit sustained heat; expect warm but not hot temperatures under continuous load.

What charger do I need to use the 25 W fast-charging on the 4000 mAh battery?

Any USB-PD 25 W or higher power adapter with a USB-C cable will deliver the rated speed.

Will my existing Nano-SIM work in the single-SIM tray alongside an eSIM profile?

Yes, the tray accepts one Nano-SIM; you can add a carrier eSIM profile in software for dual-line use.
