Looking for a flagship-quality phone without paying flagship-new prices? A refurbished mobile phone from Samsung's Galaxy S Series can give you a premium display, a strong camera, and reliable everyday performance all for under £249.
Whether you're comparing the refurbished Galaxy S21, refurbished Galaxy S22, or refurbished Galaxy S23, this guide breaks down which model fits your needs, and how to buy with confidence.
Every model here falls in the cheap mobile phones unlocked category, so you're not tied to a single network either.
Get More Galaxy S for Less
You don't need to pay full price for a new flagship to get flagship features. A well-tested refurbished Galaxy S21, S22, or S23 still delivers a vivid AMOLED display, a capable multi-lens camera, and Samsung's polished software experience just at a fraction of the original cost.
Within a £249 budget, you can realistically choose between three generations of the Galaxy S line, each offering a different balance of price and performance.
The Problem With Buying New
Problem: New Samsung flagships regularly launch north of £700, and even mid-range new phones can creep past £300–£400.
Agitate: For most everyday users browsing, messaging, streaming, and casual photography that price gap buys very little real-world benefit. You end up paying a premium for features you may rarely use.
Solution: A quality refurbished Galaxy S21, S22, or S23 gives you the same core flagship experience display, camera, performance without the new-phone markup.

-
Testing process: A genuine refurbished phone should be functionally tested battery health, screen, cameras, buttons, and connectivity.
-
Battery expectations: Battery health is usually disclosed as a percentage or capacity range; ask if it isn't listed.
-
Warranty & returns: Look for at least a 12-month warranty and a clear returns window.
-
Unlocked status: Confirm the phone is network-unlocked, not carrier-locked.
-
IMEI check: A clean IMEI check confirms the device isn't reported lost, stolen, or blacklisted.
