Why buy a Samsung Galaxy S21 Ultra 5G?

This handset, quite literally, has it all. Samsung’s brightest 6.8” Infinity-O Dynamic AMOLED 2x display and adaptable 120Hz refresh rate, Quad rear camera featuring a laser auto focus, 40 MP front camera for professional looking selfies and wireless PowerShare which allows you to charge up your Samsung wearables or even charge a friend’s phone on the move! Plus it is superfast and efficient thanks to its 5G capabilities and top of the range processor.

Samsung’s brightest Dynamic AMOLED 2X display brings everything to life in striking colour
A stunning design and the power of 5G making sharing, gaming and streaming lightening fast and buffer free
Ultrafast 5nm processor, binge-worthy battery and S Pen support gives the Galaxy S21 Ultra it’s edge
Next generation camera with 8K Video Snap


Speed, power, creativity...whether you're focused on one task or multiple tasks at once, the Galaxy S21 Ultra 5G’s delivers the ultimate performance thanks to its Exynos 2100 5nm processor. It also has your back with vault-like security and a binge-worthy battery. Stream, share or create and your content stays totally secure. The AI, Samsung Knox and high-spec Exynos processor puts vault-like security in your hands with next-level privacy controls including faster fingerprint authentication. It also monitors your settings for gaming and Game Booster blocks notifications maximising phone performance. In a nutshell, from its water and damage resistance Gorilla Glass Victus to its 8K Video and Quad camera, Samsung seem to have thought of everything for the Galaxy S21 Ultra 5G.


If you like your phone to look as good on the outside as it does on the inside, you will be thrilled when you get your hands on the Galaxy S21 Ultra. With its contour-cut metal camera and elegant camera design, it really is the ultimate show-off. The premium frosted haze effect adds to the pristine look by making fingerprints a thing of the past.


The next generation camera on the Galaxy S21 Ultra uses 8K Video Snap which captures high-res stills and Single Take which allows you to take a variety of photos and video using all three cameras at the same time. With Samsung’s new 108MP sensor, you can shoot in extraordinary detail - even at night with the 100x or 20x Zoom Lock capturing shots you never knew existed. The 8K video feature is the highest resolution on a Galaxy smartphone and has 4 times more pixels than 4K


This spectacular device allows you to use all the video cameras at once which means that you can actually be the star in your movie while directing it simply by recording front and rear together! Super Steady begs for action and Samsung have combined AI stabilisation with 60fps capture so your adventures can get a bit more adventurous as your phone shoots like an action cam. The Motion Mirror feature is also worth a mention as it lets you cast your phone to your TV so you can follow a workout routine while also watching yourself on the big screen.


The Samsung Galaxy S21 Ultra’s Dynamic AMOLED 2X display is Samsung’s brightest, most vivid smartphone display yet. See movies as the director intended and even game or binge your favourite box set in bright sunlight thanks to its brilliant and smooth 6.8” infinity-O Display. If you haven’t used a phone with a 120Hz screen before you’ll certainly be impressed with the difference. Animations and scrolling are so smooth that it can feel as though you're scanning the pages of a book or magazine rather than looking at a smartphone screen.The phone also intelligently adjusts the dynamic display 120Hz refresh rate depending on what you are doing. For example, if you are playing a game, the refresh rate maxes out at 120Hz for super-smooth graphics and gameplay while if you are simply checking a web page or listening to a podcast, the refresh rate is reduced. This brilliant feature subsequently sustains the battery life of the phone.


The Galaxy S21 Ultra 5G’s Exynos 2100 5nm processor powerhouse gives you a console-quality gaming experience and allows you to multitask like a pro. Superspeedy 5G connectivity means that you can download twice as fast and your video calls are significantly clearer. You can also combine this handset with an S Pen which is a first for the Galaxy S series.


Samsung's Galaxy S21 Ultra 5G has the most impressive battery life yet. Battery life has always been a strong point for Samsung and this phone houses a 5000mAh battery which easily offers enough power for the whole day and evening. The S21 Ultra can also be used for reverse charging, so you can charge your Galaxy Buds or other Qi-compatible accessories by placing them on the back of the phone.

Colours & Options

Colours may differ depending on supplier but the Galaxy S21 Ultra 5G’s original colour range includes Phantom Violet, Phantom Grey, Phantom White and Phantom Pink.
