Refurbished Galaxy S21 Ultra 5G

This refurbished Samsung Galaxy S21 Ultra 5G comes in Phantom Black with 128 GB of internal storage. It runs Android 11 on a Qualcomm Snapdragon 888 octa-core processor clocked at up to 2.84 GHz, supported by 12 GB of RAM. The device is fully unlocked for GSM and CDMA networks, making it ready for use with most carriers.

Best for photography enthusiasts

The quad rear camera system includes a 108 MP wide-angle lens with laser autofocus, two 10 MP telephoto lenses offering optical zoom at 3x and 10x, and a 12 MP ultra-wide lens. A 40 MP front-facing camera handles selfies and video calls. Buyers who want expandable storage via microSD should look elsewhere, as this model lacks a card slot.

6.8-inch Dynamic AMOLED 2X display

The main screen measures 6.8 inches full rectangle with a 3200 x 1440 Quad HD+ resolution and a 120 Hz refresh rate. It supports 16 million colours for vivid visuals. This display specification is the primary factor in deciding whether the handset meets your viewing and media requirements.

Questions about this item

How long does the 128GB internal storage last when recording 8K video at 24fps?

The 128GB internal storage fills quickly with 8K video at 24fps, so plan to offload footage or use cloud backup during extended sessions.

Does the Snapdragon 888 throttle and make the chassis hot during all-day use?

The Snapdragon 888 can warm the glass back under sustained load; a case helps, but expect noticeable heat during long 8K recording or gaming.

Which SIM card size does the unlocked model accept?

It takes a single Nano SIM; have an active Nano SIM from your GSM or CDMA carrier ready before first boot.
