Features

Every detail, verified.

01Network and SIM

It is unlocked for EE, O2, Vodafone, Three and all other UK networks, with 5G where available. GSMArena lists nano-SIM and eSIM support for the European model (SM-G996B); SIM support depends on the model supplied, so message us to confirm before you order if you need eSIM.

02Display

The flat 6.7-inch FHD+ Dynamic AMOLED 2X screen runs at up to 120Hz. Unlike the S21, the S21+ has Gorilla Glass Victus on both sides and an aluminium frame; GSMArena lists it at 200g.

03Performance and storage

UK models use the Exynos 2100 with 8GB of RAM and 128GB or 256GB of storage. It copes well with social, streaming and navigation; for heavy gaming a newer chip is noticeably quicker. There is no microSD slot.

04Cameras

The cameras match the S21: a 12MP main, a 12MP ultra wide and a 64MP telephoto for 3x hybrid zoom, plus a 10MP front camera. It records up to 8K at 24fps. For 10x optical zoom you would need the S21 Ultra.

05Battery and charging

Its 4,800mAh battery (when new) is the main reason to choose it over the S21, which has 4,000mAh. Charging is 25W wired and 15W wireless. The minimum battery health for each grade is listed in Key facts.

06Software updates

Samsung has stopped updating the S21+. Its last major upgrade was Android 15 (One UI 7), the last security patch was reported in November 2025, and it did not appear on Samsung's security update list on 30 Sep 2026.

Condition

Pre-owned. Tested. Honestly graded.

Every second hand Samsung S21+ we sell is pre-owned. We test it, clean it, factory reset it and remove Google (FRP) and Samsung accounts, then grade the glass back, frame and screen as Like New, Excellent or Very Good. Like New means no visible marks on the screen or body; Excellent means light signs of use, hard to spot at arm's length; Very Good means visible marks on the body, with the screen in good shape. Every grade is fully working, tested and cleaned, with at least 85% battery health. Read how we test and grade.

Compare

How it compares

Our view

Is a refurbished Samsung Galaxy S21+ worth buying in 2026?

It is a big-screen phone for light use at a low price, but it no longer gets Samsung security updates. If you bank or pay by phone, the Galaxy S22+ costs £30 more and is still supported until around February 2027.

Who it's for

It suits someone who mainly watches video, browses and messages and wants a larger, glass-backed phone for little money. For a supported large screen, see the Galaxy S22+ (from £240).
