Buy a refurbished Samsung Galaxy S23 Plus SIM-free with 85%+ battery health, 12-month warranty, 45-day returns and fast UK delivery.
The S23 Plus is the kind of phone that rewards patience. Not the one everyone talked about when it launched, not the one that made the headlines, but the one that, a week into owning it, you realise is quietly perfect for how you actually use a phone. Generous screen, dependable battery, Samsung's flagship camera intelligence doing everything you'd hope, in a form that never feels too much or too little.
Considered, capable and built to last. Every refurbished S23 Plus we sell at The Big Phone Store is tested and graded in-house — data-wiped, battery checked, unlocked and covered by a 12-month warranty.

A refurbished Samsung Galaxy S23 Plus is professionally checked before sale. A typical used Samsung Galaxy S23 Plus from a private seller may look cheaper, but it often comes with unknown battery health, unclear history and no practical warranty.
Professionally Refurbished | Typical Used Phone |
90+ point testing before dispatch | May only be briefly checked |
Minimum 85% battery health | Battery health may be unknown |
Professionally data-wiped | Data removal may not be complete |
12-month warranty included | Usually no warranty |
Clear cosmetic grade | Condition can be unclear |
Network and history checks completed | Hidden finance or network risk may remain |
Yes. Refurbished is usually safer because the phone is tested, graded, data-wiped and sold with a warranty and returns process. A private used Samsung Galaxy S23 Plus may cost less upfront, but you often lose battery checks, support, history checks and a clear route back if the phone has a fault.
Every refurbished Samsung Galaxy S23 Plus we sell is fully functional. The grade describes cosmetic condition, not performance.
Like New: Best for the cleanest look and 100% guaranteed battery health
Pristine: Best for excellent condition with very light signs of use
Very Good: Best for strong value with minor cosmetic marks
Good: Best for the lowest price if visible wear does not bother you
"The S23 Plus and S23 Ultra share the same Snapdragon 8 Gen 2 chip… and it's a remarkable processor! Every model in the S23 lineup runs the chip faster than any other Android phone released that year. That performance advantage still shows today." - The Big Phone Store Technical Team
