Xiaomi 15 Ultra 512GB 5G Dual SIM Mobile Phone, Black

The Xiaomi 15 Ultra 512GB 5G Dual SIM Mobile Phone, Black delivers the performance, camera system and everyday experience that have made it one of the most popular devices in its category. Choosing a refurbished model lets you enjoy the same features at a lower price than buying new.

Unlike a phone bought from a marketplace or a private seller, every refurbished Xiaomi phone sold by Klap is professionally tested, cleaned and prepared before it reaches you. Each device goes through a 98-point quality inspection covering the battery, display, cameras, connectivity, speakers, microphones, sensors and other key functions.

What do the grades mean?

Every Xiaomi phone is assigned a cosmetic grade based on its appearance. This helps you understand what to expect before placing your order. The grade reflects visible signs of use, while the device itself is tested to ensure it functions properly for everyday use.

Whether you choose Grade A+, A, B or C, you'll receive a fully checked device with transparent product information and clear condition details.

What's included?

Every eligible Xiaomi phone comes with a 2-year warranty, free 30-day returns and a compatible charging cable included at no extra cost.

You'll also benefit from detailed product grading, professional testing and customer support before and after your purchase, so you know exactly what you're buying.

Refurbished vs. second-hand

A refurbished Xiaomi phone is different from a typical second-hand phone. Before being listed on Klap, each device is inspected, tested and prepared according to strict quality standards.

The result is a device that has been professionally checked and backed by warranty, giving you a safer alternative to buying from an unknown seller.

A better price, without compromising on quality

A refurbished Xiaomi 15 Ultra 512GB 5G Dual SIM Mobile Phone, Black is a practical way to get the Xiaomi device you want while spending less than you would on a new one. You get a fully functional device, verified through 98 quality checks, backed by a 2-year warranty and ready for everyday use from day one.

The sale was very good. I did receive less, but that was normal because the phone had some damage while I had it. I am glad I sold it instead of keeping it in a drawer and letting it deteriorate further. I am satisfied with the services and will work with Klap again in the future. Thank you!

Excellent and prompt service. I sold my phone right before Christmas.

Crina I.

iPhone 12 64GB, Red

If the phone doesn’t sell in 30 days, the offer process restarts from 0 with new values. The information is mentioned in the terms and conditions, but it would be good for the customer to be informed about such a clause when they’re invited to choose the selling option.

Ciprian

Super satisfied, fast, and the money the next day

Szekely Mihaly

Very easy to sell your phone. Easy online value estimate. After I sent the phone, the amount confirmed by phone was in my bank account in 2 days. Very transparent process. I’ll definitely use it again!

Mihai M.

Samsung Galaxy Z Fold2 5G 256GB, Mystic Black

Very simple process. I went to the Klap site, selected the phone model I wanted to sell, and chose the voucher option. The next day the courier called, and in less than 24 hours the phone I ordered from them was on its way to me. I am glad I used them and could order a phone immediately from their site using the voucher. Thank you, guys.

Alina I.

iPhone 8 128GB, Space Gray

I thought I would not get any money back for a damaged phone that was still fully functional! Plus transport. Good job. At another repair shop, for another phone, I paid 50 lei just to replace a faulty USB port. Here I had a cracked screen, a very worn battery, and transport for a phone bought almost new for 300 lei, and I still got something back.

Daniel Gheorghiu

Samsung Galaxy J5 2015

I sold an immaculate iPhone 14 Plus Purple, like new out of the box, still under warranty! So simple—fair, fast, no hassle, no worries! I recommend Klap’s services! They were pros with me, thank you!

Marcu Virgil

Samsung Galaxy S9 64GB, Coral Blue. I sold my phone to them and at first I was unhappy with the price offered, but later I understood their evaluation and the costs. In the end it was ok, even though I wanted to get more money for the phone.

Doru I.

Samsung Galaxy S9 64GB, Coral Blue

Professionals. I sold a phone with their help, via extended sale, and the price offered was very good.
