Samsung Galaxy S25 Ultra | 256GB Storage | 12GB RAM | 6.9-inch 120Hz AMOLED Display | 200MP Main Camera
A titanium-framed stylus handset with four rear lenses and seven years of promised Android upgrades.
Condition: Used
Note: price and availability are subject to change without prior notice
Samsung Galaxy S25 Ultra is available at Mascom International for KSh 99,000, a used 256GB unit with 12GB of RAM, a 6.9-inch 120Hz AMOLED screen and a 200MP main camera. This Samsung Galaxy S25 Ultra runs the Snapdragon 8 Elite for Galaxy chip, carries a built-in S Pen and sits in a titanium frame rated IP68 against dust and water. Every unit is a carefully maintained international import in clean used condition. You can handle it before paying at our shop on the first floor of Old Mutual Building, Kimathi Street, in Nairobi CBD, or order it for delivery anywhere in Kenya.
Built for executives, lawyers, journalists and content creators across Kenya, the Samsung Galaxy S25 Ultra replaces a notebook, a camera and sometimes a laptop on a busy working day. Lawyers mark up PDF contracts with the S Pen between court sessions. Journalists shoot 4K clips and file stories from the road. Estate agents in Kilimani photograph whole rooms with the 50MP ultrawide lens and send the shots to clients within minutes. The problem with phones at this level is the cost of buying sealed. A used Samsung Galaxy S25 Ultra gives you the same chip, cameras and pen for far less money.
Unlike other electronics retailers in Kenya that sell grey imports with no after-sales backing, Mascom International checks every phone before sale and covers it with a 6-month warranty. At Mascom International, we're seeing the Samsung Galaxy S25 Ultra become the pick for buyers who want an S Pen phone with years of software support left, rather than an older model close to its last update. Customers across Nairobi tell us the 5x zoom is the feature they use most. Visit our Kimathi Street shop to test the S Pen and cameras yourself, or order on WhatsApp for pay-on-arrival delivery.
Common Questions About the Samsung Galaxy S25 Ultra
How much is the Samsung Galaxy S25 Ultra 256GB in Kenya?
The used Samsung Galaxy S25 Ultra 256GB with 12GB RAM costs KSh 99,000 at Mascom International on Kimathi Street, Nairobi CBD. That price covers a tested, carefully maintained international import, the built-in S Pen and a 6-month Mascom International warranty. Samsung never shipped a charger with this phone, so budget for a 45W USB-C charger if you lack one. Delivery is pay-on-arrival across all 47 counties. For comparison, the used Samsung Galaxy S26 Ultra 256GB costs KSh 115,000 here, which is KSh 16,000 more.
Is this Samsung Galaxy S25 Ultra used or refurbished, and what is the difference?
This Samsung Galaxy S25 Ultra is used, not refurbished: it is a carefully maintained international import that was lightly used abroad. A refurbished phone has been opened, repaired and restored by the manufacturer or a certified workshop before resale. This unit has not gone through that repair process. Battery health, small cosmetic marks and whether the original box is included vary from one unit to the next, so message Mascom International on WhatsApp for photos and the battery reading of the exact phone before you order.
Should I buy the Samsung Galaxy S25 Ultra or the Galaxy S24 Ultra in Kenya?
Pick the Samsung Galaxy S25 Ultra for a faster chip and a later end to software support; pick the used Samsung Galaxy S24 Ultra 256GB at KSh 86,000 to save KSh 13,000. The S25 Ultra runs the newer Snapdragon 8 Elite, adds a higher-resolution ultrawide camera, weighs less and has rounder corners that sit easier in the hand. It also arrived a year later, so its update window closes a year later. Both carry an S Pen and a 5x periscope zoom, and Mascom International stocks both used.
Does the Samsung Galaxy S25 Ultra work on Safaricom 5G and cope with Kenyan power cuts?
Yes, the Samsung Galaxy S25 Ultra supports 4G and 5G and works on Safaricom, Airtel Kenya and Telkom, including Safaricom 5G in towns with coverage. Most international units take one nano-SIM plus an eSIM, so you can keep a Safaricom line for M-Pesa and a second line for data. During KPLC outages, the 5000mAh battery carries you further, and Samsung states 65% charge in 30 minutes with a 45W charger. A short spell on a generator or a USB-C power bank goes a long way.
How long will the Samsung Galaxy S25 Ultra get software updates?
Samsung promises seven major Android upgrades for the Samsung Galaxy S25 Ultra, counted from its Android 15 release in early 2025. That puts support into the early 2030s, longer than most people keep a phone. For a used phone, this matters more than any single spec, because security patches keep banking apps and work email safe. Samsung sends updates over the air to imported units the same way it does to local ones, so a phone from Mascom International stays current.
Is the S Pen on the Samsung Galaxy S25 Ultra worth it for work?
The S Pen is the main reason professionals choose the Samsung Galaxy S25 Ultra over other large phones. It slots inside the phone, so it does not get lost in a bag. Doctors sign forms and sketch notes, accountants annotate spreadsheets, and university students handwrite lecture notes that Samsung Notes can convert to typed text. Samsung removed the Bluetooth remote features from this generation's pen, so it no longer works as a distant camera shutter. For writing, drawing and signing, it works exactly as expected.
How good is the Samsung Galaxy S25 Ultra camera for content creators?
The Samsung Galaxy S25 Ultra has four rear cameras: a 200MP main, a 50MP ultrawide, a 10MP 3x telephoto and a 50MP 5x periscope telephoto. Content creators get 8K video at 30fps, 4K at up to 120fps for slow motion, and 10-bit HDR recording. Optical stabilisation on the main camera and both zoom lenses keeps handheld footage steady. Buyers throughout Kenya report that the 5x lens lets them film weddings, graduations and church events from the back of the hall without losing detail.
Who should buy the Samsung Galaxy S25 Ultra and who should skip it?
Buy the Samsung Galaxy S25 Ultra if you write, sign or sketch on your phone, shoot a lot of zoom photos and want years of updates at a used price. Skip it if you want a compact phone: at 218g and 6.9 inches, it fills a pocket and tires small hands. Those buyers are better served by the used Samsung Galaxy S26 at KSh 88,000. If you would rather read documents on a folding screen, the used Samsung Galaxy Z Fold6 256GB at KSh 96,000 is in stock.
Technical Specifications
Display and Screen Quality
- 6.9-inch Dynamic AMOLED 2X screen at 1440 x 3120 pixels — sharp enough to read small print in contracts without zooming in.
- 120Hz LTPO refresh rate — scrolling looks fluid, and the screen slows itself on still images to save battery.
- Up to 2600 nits peak brightness — the screen stays readable outdoors in strong midday sun.
- Corning Gorilla Armor 2 cover glass with an anti-reflective finish — fewer glare spots and better resistance to scratches.
- HDR10+ support — streaming apps show brighter highlights and deeper shadows in supported shows and films.
Processor and Performance
- Qualcomm Snapdragon 8 Elite for Galaxy on a 3nm process — a smaller process means the chip does more work per unit of battery.
- Octa-core CPU with two cores at 4.47GHz and six at 3.53GHz — heavy and light tasks each run on suitable cores.
- Adreno 830 graphics — handles demanding mobile games such as Call of Duty Mobile and Genshin Impact at high settings.
- Galaxy AI tools including Live Translate, Note Assist and photo object removal — translation and summaries without extra apps.
- Released on Android 15 with seven major OS upgrades promised — software support runs into the early 2030s.
Memory and Storage
- 12GB RAM — keeps WhatsApp, email, banking, maps and several browser tabs open without reloading when you switch.
- 256GB UFS 4.0 storage — UFS 4.0 is a fast storage standard, so apps open and files copy quickly.
- Room for about 80,000 photos at the default 12MP setting, before apps and system files take their share.
- Or about 10 hours of 4K video at 30fps, which uses roughly 350MB for every minute recorded.
- No microSD slot — move older files to cloud storage or a USB-C flash drive through the OTG-capable port.
Camera Hardware and Imaging
- 200MP main camera with f/1.7 aperture and optical stabilisation — fine detail in daylight and steadier shots in dim rooms.
- 50MP ultrawide with a 120-degree field of view — fits whole rooms, large groups and tall buildings into one frame.
- 10MP 3x telephoto with optical stabilisation — natural-looking portraits from a comfortable distance.
- 50MP 5x periscope telephoto with optical stabilisation — distant stages, road signs and wildlife come out clear.
- 12MP front camera recording 4K at up to 60fps — clean video calls and selfie vlogs with plenty of detail.
Battery and Charging
- 5000mAh battery — a full working day of calls, maps, email and video on one charge for most users.
- 45W wired charging — Samsung states 65% in 30 minutes when paired with a compatible 45W charger.
- 15W wireless charging, Qi2 Ready — rest it on a wireless pad at your desk with no cable needed.
- 4.5W reverse wireless charging — tops up Galaxy Buds or a smartwatch placed on the back of the phone.
- USB Type-C 3.2 port with DisplayPort output — connects to a monitor for the Samsung DeX desktop layout.
Connectivity and Build
- 5G in standalone and non-standalone modes on Sub-6 bands — works with both newer and older 5G network setups.
- Nano-SIM plus eSIM on most international units — two lines active at the same time on one phone.
- Wi-Fi 7 tri-band — faster and steadier connections on newer home and office routers.
- Bluetooth 5.4 and NFC — earbuds pair quickly, and NFC supports tap-to-pay and quick file sharing.
- IP68 rating in a titanium frame, 218g and 8.2mm thick — survives dust and submersion to 1.5 metres for 30 minutes.
Package Contents
The used Samsung Galaxy S25 Ultra comes as the handset with its S Pen docked inside the frame. Each phone is an individual international import, so the retail box, cable and paperwork vary between units; ask on WhatsApp what comes with the unit you want. Samsung did not include a charger even when this model was sold sealed, so a compatible 45W USB-C charger is sold separately at Mascom International, along with cases and screen protectors.
