As the new S25 launches, 2024's Samsung S24 has started to see some noticeable discounts. We've rounded up the best deals below.
One of the best places to check for deals is always the official Samsung store – Samsung typically offers some pretty appealing deals that include traditional discounts but also free accessories, other devices like Chromebooks or significant cashback on older devices that can reduce the up front cost dramatically.
You can also compare Samsung's current offers to the handset-only and contract deals to see which works out best for you.
We've tested the S24. So you'll want to read our full reviews on the Samsung S24, S24+, and S24 Ultra before you buy.

Samsung Galaxy S24 Ultra
Samsung's new S24 range debuted with AI stealing the headlines, promising to make your life easier, improve your communication, save time, and make photography far more versatile. They also deliver an impressive six years of security updates, and while hardware improvements are fairly iterative, expect brighter screens and a more robust build.
Right now, you can get a free pair of Samsung Galaxy Buds FE, and a Samsung Fit3 activity tracker when you buy a last-gen S24 from Samsung. That might be tempting, but it's actually £139 cheaper to buy the bundled tech separately from other retailers.

Best Samsung Galaxy S24 contract deals
There are hundreds of contract deals for the Galaxy S24 range and they change all the time. The key to getting a good deal is knowing how to work out the total cost to compare to other options. Use our phone contract calculator below to do that for deals you're weighing up, and bear the following in mind before you take the plunge:
Check the period over which you'll pay off the handset. Many providers now offer 48-month repayment plans, which can make the monthly cost appear low but may not save you money in the long term.
Find out how much the Sim price may rise after the first year, and remember you can switch the Sim part of the deal after the two years are up (see our 'top pick' Sim deals below).
Watch out for up-front costs, and look out for other ways to save, such as trading in money for your old handset.
Compare contract deals on theSamsung Galaxy S24, theGalaxy S24 Plus and theGalaxy S24 Ultra and use our calculator to work out total cost.

Why you can trust our mobile phone tests
We buy every mobile phone we test anonymously to make sure it's the same product that you buy – and to keep our results impartial.
Our phones go through more than 40 different tests in lab conditions. Our camera testing is in-depth – from overall picture quality in daylight conditions, to evaluating colour accuracy, image stabilisation and quality of the optical zoom. We use a robotic arm to interact with the phone to measure its battery life through the day at different brightness settings, and test how long it takes to charge, and benchmark the speed of each phone's processor to compare it to others on the market as well as putting it through daily tasks to make sure you don't end up with a sluggish performance.
For your peace of mind, we also test if the phone is durable enough to survive getting caught in the rain or being dropped on hard surfaces. Read more about how we test mobile phones.
