Discover the best way to buy a second hand Samsung Galaxy S21 Ultra. When you buy a refurbished S21 Ultra from The Big Phone Store, you always know you're getting a fully tested device in perfect working order.
108MP Camera: With a truly insane number of megapixels, the quad-camera setup on the rear provides up to 10x optical zoom, and up to 100x Space Zoom!
Samsung Knox Vault: Secure hardware keeps your passkeys and biometrics encrypted at all times.
S-Pen compatible: The S21 Ultra is fully compatible with Samsung's digital pen, or S-Pen, previously found only on Samsung's Galaxy Note phones.
(Updated 2024. Reviewer: Andrew Norris)
The S21 Ultra has everything you'd expect from an Android phone made by Samsung. Despite its age, the S21 Ultra still has all the most important key features of a high-end Samsung phone, such as S-Pen compatibility (which for me is without a doubt the most valuable feature of any Samsung phone).
Most of all, I love Samsung's 'Ultra' cameras, esspecailly the amount of detail you can get out of the 108MP sensor on the S21 Ultra.
Now that we're a few years out from its inital release, the price of a refurbished S21 Ultra has plummeted. This phone is available at up to 60% off or more compared to its original price.

I've been stung by buying phones online but after looking at all the positive reviews, I took the chance and was impressed by the quality and how fast it arrived. I will definitely buy from TBPS in the future.
