6.5 Minutes BY The Three Team

The Samsung S21 is set to be the year’s must-have Android, offering simply amazing technology that redefines the sector, with an array of new features and attractive, sleek design. All of the S21 models support 5G so they are the perfect partner for Three, Ireland’s only network with 5G in every county.

The S21 series is a major step up from the S20, S20+ and S20 Ultra, but with so many new features and a range of different models to choose from, it can be difficult to decide which one is right for you. That’s why we’ve produced this guide, to help you compare each model. 

There are three phones in the new Galaxy range:

  • Samsung S21
  • Samsung S21+
  • Samsung S21 Ultra

Before we dive into each individual phone, here’s a quick overview of the key specs of the Samsung Galaxy S21 Series:

The S21 is the standard model of the new range, but rest assured, there’s nothing standard about the array of technology that it packs. Compared to its S20 predecessor, the S21 delivers smarter cameras, faster performance and a sleeker design. It’s easily one of the best smartphones available anywhere in the world. 

Samsung S21 Specs


First impressions are really good - the phone’s 6.2-inch Full HD+ screen sits into a sleek, contour-cut metal housing. The picture quality is excellent, with rich, deep colours and pin-sharp clarity. 


More and more of us are looking for more versatility and better quality from our phone cameras and the S21’s camera is a major plus that will bring out the photographer or movie-maker in you.

It’s just as good for shooting video as it is for stills, with a triple-lens on camera on the rear offering 30x Space Zoom, 3x optical zoom and enhanced Night Mode for low-light photography. Switch to video mode and you can shoot in a crystal-clear 8K video – a real point of difference over lesser phones.


Samsung have put serious research and development into battery technology to support all the functions of the new phone. The S21’s battery means you can keep going all day, because of the power and efficiency in the way it has been designed. The Galaxy S21 is also IP68-Rated, which means it can withstand dust, dirt and sand, and is water resistant up to a maximum depth of 1.5m underwater.

S21 Price

While the specs are market-leading, Samsung have kept the S2’s price at a very competitive level. For Bill Pay customers, you can either join Three or upgrade and get this flagship smartphone for just €199 on our €59.02 plan or for €799.99 on prepay.

Our view

Great spec, great value, delivers everything it promises – we believe the S21 is set to become the phone that all other smartphones will be compared against.


While the S20 is set to be the flagship smartphone for the widest audience, the S21+, as the name suggests, offers additional features and better spec, still at a competitive price.

Samsung S21+ Specs


The first difference you’ll notice with the S21 is the larger screen, at 6.7-inches. The extra dimensions make the it particularly attractive for TV, gaming or simply for work. The AMOLED display means the touch screen is integrated into the screen technology, giving you exceptional clarity and a screen that reacts to the light in your environment, so it is easier on your eyes. 


Like the S21, the camera on the S21+ is triple-lens, allowing you a greater zoom function and sharpness, with an array of features to help you get the perfect shot. Shoot in high quality with 8K video or capture the moment without fear of missing it thanks to Single Take 2.0, where you shoot an image once, but get multiple image options to save.


Additional technology needs additional battery power, and Samsung have taken battery technology to the next level with the S21+.  The 4500 mAh battery means you have a phone than can do more for longer, and it’s more secure because the S21+ IP68-rated, meaning it’s water and dust resistant.

S21+ price

The extra features mean a little more in cost, but with Three, you can get amazing value on the Samsung Galaxy S21+ , yours for €449 on our €59.02 plan or €989.99 on prepay

Our View

The big ‘plus’ of the S21+ is in the screen size, so if you are comfortable with a slightly larger device, the benefits of this phone are well worth the extra.


For the S21 model that takes all of the technological advances to the next level, the Samsung S21 Ultra more than delivers. Thanks to its Exynos 2100 processor, it is the best smartphone that Samsung has to offer with unrivalled power and efficiency thanks to its 12GB RAM.

It will be the first of the Galaxy S family that supports the Samsung S-Pen (sold separately) and it’s IP68-rated, meaning it is resistant to dust and water - perfect for outdoor use.


The first feature to take in is the ultra-impressive 6.8-inch screen, with Samsung’s Infinity-O display. This advanced system offers a cinematic experience for movies and games, and the screen technology puts more in view, whether you're browsing the internet or checking social media.


Samsung have pulled out all the stops with the S21 Ultra’s camera, delivering 108 Megapixels, with Ultra-wide and Tele lenses. On the front, you get a fantastic 40 Megapixels selfie camera, so no excuse not to look good! The camera technology means you can shoot the highest-quality stills even in low light, while for moving pictures it becomes a serious 8K video camera, capturing video at 24fps, the worldwide standard for cinema projectors.


Technology is only as good as the battery that drives it, but the S21 Ultra boasts a massive 5000 mAh battery. It delivers more than enough power for you to enjoy the phone all day and share some power with friends or charge additional gadgets with wireless power-sharing.


Behind all of this technology is a processor that gives you unrivalled power and efficiency with 12GB RAM from us. It will be the first of the Galaxy S family that supports the Samsung S-Pen (sold separately) and it’s IP68-rated, meaning it is resistant to dust and water to a high level - perfect for any outdoor use.
