Samsung Galaxy S25 Ultra 5G 512GB Dual Sim Whitesilver combines Samsung’s Ultra camera system, large anti-reflective display and built-in S Pen in a premium flagship design. This Whitesilver model is brand new, sealed and network unlocked, with 512GB storage, 12GB RAM, 12-month warranty support, fast nationwide delivery across South Africa and secure checkout from ExcellTronics.
Samsung’s complete Ultra flagship
The Galaxy S25 Ultra is designed for customers who want Samsung’s most capable S25-series experience. Its large 6.9-inch display gives photographs, video, documents and games room to breathe, while the integrated S Pen adds precise writing, selection and editing. The Whitesilver finish keeps the design understated and professional, and this listing clearly identifies the exact 512GB storage configuration being purchased.
Samsung equips the SM-S938B/DS family with the Snapdragon 8 Elite for Galaxy platform and 12GB RAM. The combination supports demanding applications, multitasking, high-resolution photography and Galaxy AI features. Actual performance and feature availability can vary with software, temperature, network conditions and regional configuration.
6.9-inch QHD+ Dynamic AMOLED 2X display
The 6.9-inch Dynamic AMOLED 2X display has a QHD+ resolution of 3120 × 1440 and an adaptive refresh rate up to 120Hz. It delivers sharp text, deep contrast and smooth motion for streaming, browsing, gaming and creative work. Samsung’s anti-reflective display treatment helps reduce distracting reflections, while high outdoor brightness supports visibility in bright conditions. The actual viewable area is slightly smaller because of the rounded corners and camera opening.
Corning Gorilla Armor 2 helps protect the front surface against everyday scratches and impacts. A protective case and careful handling are still recommended because no glass phone is damage-proof.
200MP quad-camera system
The rear camera array combines a 200MP wide camera, 50MP ultra-wide camera, 50MP telephoto camera with 5x optical zoom and 10MP telephoto camera with 3x optical zoom. This gives the S25 Ultra flexibility for detailed everyday images, broad landscapes, close portraits and distant subjects. Optical image stabilisation supports the main and telephoto cameras, helping reduce unwanted movement in compatible modes.
The 12MP front camera supports selfies and video calls. Samsung’s ProVisual Engine and Galaxy AI editing tools can assist with detail, colour, low-light scenes and object-aware edits. The phone also supports high-resolution UHD 8K video recording. Final results depend on lighting, focus, motion and camera settings.
Built-in S Pen
The integrated S Pen is stored inside the phone, making it available without carrying a separate accessory. It can be used for handwritten notes, precise selections, drawing, signing documents and detailed editing. The S Pen is one of the main reasons to choose the Ultra over the standard S25 or S25 Plus, especially for customers who work with documents, mark up images or prefer handwriting to on-screen typing.
Galaxy AI and productivity
Galaxy AI features can assist with search, writing, translation, summaries, transcription and photo editing across supported Samsung and Google services. Availability varies by language, region, application, account and software version, and some features require an internet connection or account sign-in. Samsung DeX also allows compatible external-display workflows for customers who want a desktop-style workspace.
Smart Switch helps transfer supported contacts, photographs, messages and applications from an older Android phone or iPhone. One UI provides Samsung’s familiar interface, security controls and customisation options.
512GB storage with 12GB RAM
This listing includes 512GB internal storage and 12GB RAM. The 512GB version is well suited to customers who record substantial high-resolution video, keep large photo libraries, install demanding games or want additional long-term storage headroom. Available user storage is lower because the operating system and pre-installed software use part of the stated capacity.
The S25 Ultra does not use a microSD memory-card slot, so storage should be selected according to long-term needs. This product page is specifically for the 512GB Whitesilver version.
5,000mAh typical battery
A 5,000mAh typical battery supports extended mixed use, though actual endurance depends on signal strength, screen settings, applications, camera activity and background services. Charging speed depends on the compatible cable and adapter used. Samsung does not include a wall charging adapter in the standard sealed retail box, so customers who require one should use a suitable USB-C charger sold separately.
Wireless charging and Wireless PowerShare are available with compatible accessories and devices. Charging performance can vary with alignment, case thickness, temperature and power source.
Premium construction and IP68 protection
The Galaxy S25 Ultra uses a titanium frame and Gorilla Armor 2 on the front. Samsung lists an IP68 rating for resistance to dust and freshwater under controlled laboratory conditions. Water resistance is not permanent and may decrease with normal wear, impact or repair, so the phone should still be handled carefully around liquid.
Dual SIM, eSIM and 5G connectivity
The SM-S938B/DS family supports dual-SIM and eSIM configurations, subject to regional software and network support. It is sold network unlocked for compatible South African mobile networks. 5G requires suitable coverage, a compatible SIM and an appropriate plan. Connectivity features include Wi-Fi, Bluetooth, NFC and USB-C, with Wi-Fi 7 availability depending on the router, network and market.
