Samsung Galaxy S21 5G is in stock at Mascom International, priced at KSh 31,000 for a used unit with 256GB storage and 8GB RAM. It pairs a 6.2-inch 120Hz Dynamic AMOLED 2X display with a triple rear camera led by a 12MP main sensor and a 64MP telephoto lens. Each Samsung Galaxy S21 5G is a carefully maintained international import with a 4000mAh battery, IP68 water resistance, stereo speakers and eSIM support. Samsung fitted a 5-nanometre chip, either Snapdragon 888 or Exynos 2100 depending on import region. Visit our first-floor shop at Old Mutual Building on Kimathi Street, Nairobi CBD.
Designed for journalists, estate agents and executives who carry their phone in a shirt pocket, the Samsung Galaxy S21 5G handles one-handed calls, quick edits and long video shoots. Most buyers face a trade-off: small phones usually come with small storage. This Samsung Galaxy S21 5G removes that worry with 256GB of space and 8K recording at 24 frames per second. An estate agent in Kilimani can film a full property walkthrough, edit it and share it on WhatsApp before the next viewing. A journalist covering a Westlands press event can shoot hours of 4K clips without deleting old files.
Where most Nairobi electronics shops sell used phones without testing or written cover, Mascom International checks each Samsung Galaxy S21 5G before sale and includes a 6-month warranty. At Mascom International, we're seeing steady demand for this model from buyers who find newer phones too large. Customers across Nairobi tell us the 169-gram body and 120Hz screen make it a pleasure to use on a crowded matatu. Come to Kimathi Street to hold it and test the camera, or order through WhatsApp for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the Samsung Galaxy S21 5G
What is the Samsung Galaxy S21 5G 256GB price in Kenya?
The Samsung Galaxy S21 5G 256GB with 8GB RAM sells for KSh 31,000 in used condition at Mascom International, Nairobi CBD. The price includes a tested and factory-reset phone, our 6-month warranty and pay-on-arrival delivery to all 47 counties. Samsung shipped this model without a charger, so a compatible 25W adapter is an extra purchase in store. The Samsung Galaxy S21 FE 5G 128GB costs KSh 2,000 less at KSh 29,000, while the Samsung Galaxy S21 Ultra 5G costs KSh 10,000 more.
Is this Samsung Galaxy S21 5G used or refurbished, and what is the difference?
Our Samsung Galaxy S21 5G is used: a lightly used international import kept in clean condition by its previous owner, never refurbished. Refurbishment means a manufacturer or certified partner has replaced parts and recertified the phone. A used phone keeps its original parts and passes through our own checks of the display, cameras, speakers, buttons and SIM signal. Battery health and small cosmetic marks differ from one unit to the next, so message us on WhatsApp for photos of the exact phone.
Should I pick the Samsung Galaxy S21 5G or the Samsung Galaxy S22 256GB?
The Samsung Galaxy S21 5G saves you KSh 5,000 against the used Samsung Galaxy S22 256GB at KSh 36,000, with the same storage size. The Samsung Galaxy S22 is one generation newer, with a newer chip, a refreshed camera system and a longer software support window. The Samsung Galaxy S21 5G still offers a 120Hz screen, 8GB RAM, 8K video and IP68 protection. Choose this phone if price matters most; choose the newer model if you plan to keep your phone four years.
Does the Samsung Galaxy S21 5G support eSIM on Safaricom and Airtel Kenya?
Yes, the Samsung Galaxy S21 5G supports eSIM alongside a physical nano-SIM, so you can run Safaricom and Airtel Kenya lines together. Many dual-SIM units take two nano-SIMs plus an eSIM, using any two at once. Visit a Safaricom or Airtel shop with your ID to get an eSIM profile, then scan the QR code in Settings. Its 4G band list covers bands 1, 3, 7, 28 and 40 on both import versions. Telkom users can keep a physical SIM in the tray.
Is the Samsung Galaxy S21 5G good for content creators and journalists?
The Samsung Galaxy S21 5G suits content creators and journalists because it records 8K at 24fps and 4K at 60fps with gyro stabilisation. The 64MP telephoto offers 3x hybrid zoom, handy for framing a speaker from the back of a hall. With 256GB on board, you can store about 12 hours of 4K footage before offloading to a laptop. The 10MP selfie camera records 4K too, so vlogs and live updates from Nakuru or Kisumu look sharp on YouTube.
Is the Samsung Galaxy S21 5G comfortable to use with one hand?
Yes, the Samsung Galaxy S21 5G is one of Samsung's more compact S-series phones, measuring 151.7mm tall and weighing about 169 grams. Its 6.2-inch screen lets most people reach the top corners with a thumb, which helps when you hold a handrail on a matatu or a bag on a boda boda. The frame is aluminium with Gorilla Glass Victus on the front. The back is plastic, which shrugs off small knocks better than glass and stays light.
Who should buy the Samsung Galaxy S21 5G, and who should skip it?
The Samsung Galaxy S21 5G is right for buyers who want a small, quick Samsung with 256GB and strong video for KSh 31,000. Executives, agents and reporters will value its size and storage. Skip it if battery life is your top priority, as heavy users may need a midday top-up; the Samsung Galaxy S21 FE 5G carries a bigger 4500mAh cell. Skip it also if you need long-range zoom, where the Samsung Galaxy S21 Ultra 5G and its 10x periscope lens make sense.
How long will the Samsung Galaxy S21 5G keep getting updates?
The Samsung Galaxy S21 5G launched in January 2021 with Android 11 and has received its four promised major Android upgrades, reaching One UI 7. No further major Android versions are expected for it. Popular apps such as M-Pesa, KCB, Equity, WhatsApp and the KRA iTax portal still work on it today. Buyers who want years of fresh Android versions should look at the Samsung Galaxy S23 FE 128GB, which Mascom International sells used for KSh 38,000.
