At our company, we’re committed to providing reliable, long-lasting phones, including the used S21. Even our ‘poor condition’ pre-owned phones maintain a minimum of 85% battery health, ensuring prolonged power with fewer interruptions. Our cheap phones are available in great condition, highlighting their effective working capacity and appearance similar to new devices. This surpasses the offerings of many competitors, who often sell devices with lower battery health.
Battery health measures how well a battery retains its charge compared to its original state. An 85% battery health indicates the battery is still in good condition, delivering better performance and longer usage between charges. It’s important to note that this percentage reflects the efficiency of the battery, not its charging capacity.
Most of our devices come with a 12-month warranty, protecting your purchase against material defects for a full year. Should an issue arise that is covered by the warranty, we will resolve it at no extra cost to you. This is part of our commitment to ensuring you have a reliable and worry-free experience with your device. To find out more, visit our warranty page.
The refurbished Samsung devices we sell undergo a meticulous process involving over 90 individual checks to ensure they meet our rigorous standards. These checks cover all aspects of the phone, including functionality, battery health, cosmetic damage, and overall condition. We guarantee that every phone purchased is in excellent working order and has been data wiped, making it ready for reliable use. Unlike many competitors, who may not perform such extensive testing, we ensure our phones meet the highest standards of quality.

Our grading conditions range from ‘Brand New’ to ‘Poor’, so you can pick your device to suit your budget! For first-time buyers, we recommend buying ‘Like New’ or ‘Pristine’. If you're considering a flagship Android device, a refurbished Samsung S21 is an excellent choice.
Brand New—sealed as you would expect. These phones have never been used before, and they even come with their manufacturer’s warranty!
Like New- Almost New (Out of Box). This is our best-refurbished condition, and the device has no cosmetic damage. Besides not being in the original box, this device is essentially brand-new!
Pristine—Very Slight Signs of Use. The excellent condition phones clearly show that the previous owner has taken great care of their device, so while there may be some minor cosmetic imperfections, 99% of the phone is in perfect condition.
Very Good- Light Signs of Use. These phones show light signs of usage and may have visible cosmetic marks, but they won’t be visible when the screen is on. Buying ‘Very Good’ is ideal for those who are budget-conscious and don’t mind a few imperfections.
Good- Medium Signs of Use. These are phones that have had a few bumps! There are visible cosmetic marks, and the device shows medium signs of use, but its functionality is completely unaffected!
Poor- Heavy Signs of Use. Fully tested and in perfect working order, these phones are the cheapest way to get the model you want at the cost of cosmetic quality. Scratches, cracks, and screen burns are all possible.
