Samsung Galaxy S23 Ultra is now available at Mascom International for KSh 73,000, supplied as a carefully maintained international import with 512GB of UFS 4.0 storage and 12GB of LPDDR5X RAM. This Samsung Galaxy S23 Ultra pairs a 6.8-inch Dynamic AMOLED 2X screen, the Snapdragon 8 Gen 2 for Galaxy processor, a 200MP main camera, and an in-body S Pen. The unit was lightly used internationally and never deployed locally in Kenya before reaching our store. Find the Samsung Galaxy S23 Ultra at Mascom International, Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD.

Samsung Galaxy S23 Ultra suits Kenya's business executives, content creators, photographers, and university students who want a top-tier device at a used-import price. The 200MP camera and dual telephoto lenses handle wedding shoots in Karen, event coverage at the KICC, and wildlife photography on Mara trips without the cost of a brand-new equivalent. The in-body S Pen replaces a separate notepad during client meetings and contract markup. For buyers priced out of newer Ultra models, the Samsung Galaxy S23 Ultra brings 10x optical zoom, a 5000mAh battery, and Samsung DeX desktop mode at KSh 73,000.

Unlike other electronics retailers in Kenya that sell only sealed new stock, Mascom International offers the Samsung Galaxy S23 Ultra as a clean used import that passed full functional testing before reaching our shelves. Buyers across Nairobi report that the Snapdragon 8 Gen 2 still runs demanding 2026 apps, mobile gaming, and 8K video editing without lag three years after launch. The IP68 rating and Gorilla Glass Victus 2 hold up to daily Nairobi matatu commutes and unexpected rains. Test the Samsung Galaxy S23 Ultra at our Kimathi Street store, or order it with pay-on-arrival delivery to any of Kenya's 47 counties.

Common Questions About the Samsung Galaxy S23 Ultra

What is the difference between this used Samsung Galaxy S23 Ultra and a refurbished one?
This unit is used, not refurbished, meaning the original hardware stays intact with no part swaps or factory reconditioning. A refurbished phone typically has its battery, screen, or other components replaced and reset by a vendor. This Samsung Galaxy S23 Ultra is a carefully maintained import, lightly used abroad and never deployed locally in Kenya. It passed Mascom International's functional testing for screen, battery health, cameras, charging, and biometrics. You collect the genuine device at KSh 73,000, backed by a 6-month Mascom International warranty covering hardware functionality.

Is the Samsung Galaxy S23 Ultra still worth buying in 2026?
Yes, the Snapdragon 8 Gen 2 for Galaxy remains quick enough for everyday and demanding tasks three years after its February 2023 launch. The chip handles banking apps, video calls, mobile gaming, and multitasking across four apps without slowdown. Samsung committed to four Android upgrades and five years of security patches, so the device now runs One UI 8.5. At KSh 73,000 used, the Samsung Galaxy S23 Ultra costs far less than a new model while keeping the 200MP camera, S Pen, and 10x zoom that define the Ultra line.

How good is the 200MP camera for content creation?
The 200MP main sensor captures fine detail for billboards, print work, and cropping flexibility that lower-resolution phones cannot match. Its f/1.7 aperture and large 1/1.3-inch sensor pull in light during evening events and indoor shoots across Nairobi. The 10x optical periscope and 3x telephoto cover distant stages, wildlife, and tight portraits, while the 12MP ultra-wide adds autofocus for close detail shots. Kenya's content creators report publication-ready stills and stable 8K video, making the Samsung Galaxy S23 Ultra a practical tool for weddings, events, and social media work.

How long does the battery last and how fast does it charge?
The 5000mAh battery comfortably lasts a full Westlands-to-Karen-and-back workday of calls, navigation, and social media for most users. Wired 45W charging refills roughly 65% in about 30 minutes when paired with a certified Samsung 45W adapter. Third-party chargers without the right authentication chip may cap charging near 25W, so the matching adapter matters. The phone also accepts 15W wireless charging and 4.5W reverse wireless charging to top up Galaxy Buds. Real-world endurance holds steady in Kenya's warmer Mombasa and Kisumu climates.

Does the Samsung Galaxy S23 Ultra support Safaricom 5G?
Yes, the Samsung Galaxy S23 Ultra carries full 5G support for Safaricom 5G coverage across Nairobi, Mombasa, Kisumu, and Nakuru. It also works on Airtel Kenya and Telkom Kenya 4G and 5G bands, with dual SIM that handles a Safaricom personal line and an Airtel business line at once. Wi-Fi 6E and Bluetooth 5.3 keep downloads, file transfers, and accessory pairing quick. M-Pesa transactions, Lipa na M-Pesa till payments, and banking apps from KCB, Equity, and NCBA run smoothly on the chipset and fast connectivity.

What can the S Pen actually do for daily work?
The in-body S Pen pulls out of the phone itself, charges inside the device, and supports note-taking, document markup, and signatures without any separate accessory. It converts handwriting to typed text, useful for capturing notes during client meetings and site visits. Air Command opens screen capture, content extraction, and screen-off memo with one button. Bluetooth low-latency lets the S Pen act as a remote shutter for group photos and presentations. Business users find it replaces a notepad and stylus tablet they previously carried as extra gear.

What is included with this used import and what warranty applies?
This used Samsung Galaxy S23 Ultra ships with the handset, a compatible USB-C cable, and a SIM ejector tool, since used imports do not arrive in sealed Samsung retail packaging. Samsung never bundled a charger with this model, so we recommend adding a certified 45W adapter, stocked separately at Mascom International. The device carries a 6-month Mascom International warranty covering hardware functionality. Our Nairobi CBD service desk handles any warranty claims directly, with same-day support for walk-in customers across the central business district.
