We’ve partnered with Three and have access to 3 mobile deals that you won’t find elsewhere – even on Three’s own site.
Whilst you save money on these deals you will receive the exact same product and services as buying direct from Three themselves. All orders, returns and customer services will be provided by Three.
These deals cover SIM Only plans, mobile phones, home broadband, and mobile broadband, so almost every product category offered by Three.
There are great deals on Three all year round, and below you’ll find details of some of the ongoing highlights, while above you can purchase any that catch your eye. But it’s now Black Friday, and Three’s Black Friday deals have now started too.
These include various phone, SIM Only, and even mobile broadband and home broadband deals, so there’s a lot to get stuck into. You can find more details of these deals below.
Currently, the best Three mobile SIM Only deals include a number of Black Friday deals that bring significant savings. All deals come with Three+ Rewards, 5G at no extra cost, and tethering included.
A great deal for those looking for a cheap deal that still doesn’t compromise on data. For just £7 a month you can bag 30GB of data, unlimited minutes and unlimited texts on a 12-month contract.
A brand new deal with 40GB of data, unlimited minutes and texts for just £8 a month on a 12-month plan.
For just £9 a month you can now get a whopping 60GB of data, which again comes with unlimited minutes and texts on a 12-month plan.
Those looking for a nice chunk of data should consider the 120GB for £10 a month deal on a 12-month plan.
Those needing a large chunk of data should consider this 250GB deal for £14 a month. That’s also on a 12-month contract.
Never worry about running out of data again with unlimited data for £20 a month on a 24-month contract.
We've got a host of exclusive deals on the latest contract phones, including flagships and more affordable mid-range options.
The brand new iPhone 16 has arrived and right now you can get it with a hefty 150GB of data for just £30.00 per month plus £30 upfront. That includes unlimited minutes and texts too, and is on a 36-month contract.
If you’d rather have an Android phone then consider the Samsung Galaxy S24, which is available for just £21 per month with £25 upfront. That’s also with 150GB of data and unlimited minutes and texts, and it’s on a 36-month contract.
The Samsung Galaxy S24 FE is a slightly cheaper alternative to the Galaxy S24, and right now you can get it for just £19.50 per month and £20 upfront, on all the same terms – so 150GB of data, unlimited minutes and texts, and a 36-month contract.
If you’re after a high-end foldable then we’ve got you covered with the Samsung Galaxy Z Flip 6, which is currently down to just £32 per month and £40 upfront, on a 36-month contract with 150GB of data, and unlimited minutes and texts.
If you don’t need the latest model, then you can also get the still-excellent iPhone 15 for a bargain £28 per month plus £25 upfront. Once again that’s on a 36-month contract with unlimited minutes and texts, and 150GB of data.
The flagship Google Pixel 9 is also on sale, with this super-smart smartphone costing just £21 per month plus £25 upfront currently. And again that’s with 150GB of data, unlimited minutes and texts, and on a 36-month contract.
There’s also a deal on the AI-packed Google Pixel 8a for £15 per month plus £25 upfront, which again gets you 150GB of data on a 36-month plan.
For another mid-range option, consider the Honor 200 5G, which right now you can grab for just £15 per month and £25 upfront. That’s on a 36-month contract with 150GB of data.
Or there’s the always-affordable Motorola Edge 50 Neo, which is even cheaper than usual currently, at just £13.72 per month and £10 upfront. That again is a 36-month contract with 150GB of data and unlimited minutes and texts.
Right now, you can get a Black Friday offer of £19 per month for Three 5G Broadband or Three 4G Broadband. That’s down from a typical price of £24 per month, saving you £120 over the life of the contract. That’s with unlimited data and no upfront cost.
Or if you don’t want to be tied into a lengthy contract you can get Three 5G Broadband for £28 per month on a 1-month plan.
If you have a 5G signal at home then we’d always recommend Three 5G Broadband, especially as this deal is the same price for both options. But Three 4G Broadband is an excellent choice for homes without 5G – and it still supports download speeds of up to 600Mbps.
If you’re after a mobile broadband option – so you can get all your gadgets online when away from home – then right now you can get the Three 5G MiFi on a 24-month plan with unlimited data for £28 per month.
Or you can get the Three 4G MiFi on a 24-month contract with unlimited data for £22 per month.
In both cases that’s with no upfront cost, and if you don’t want to be tied in to such a long contract, you can get the Three 4G MiFi on a 1-month plan with a £39 upfront cost for £32 per month.
If you’re already a Three customer then you’ll be eligible for Three existing customer deals. These 3 phone deals for existing customers change regularly, but the network often rewards its users by giving them discounts on its product range, including often phones, SIM Only plans, and broadband.
If you’re already a Three customer then you might be eligible for an upgrade, even if you’re still within your contract. Generally you can upgrade in the last 30 days of a contract, but for full details, check out our Three upgrades guide.
There are lots of reasons to choose Three above and beyond the excellent value offered by these 3 mobile deals. Highlights of the network include the following things.
Three’s 4G coverage reaches 99% of the UK population, so wherever you are and wherever you go, you’ll almost always have a signal.
Its 5G coverage is also growing at a rapid rate, and may soon be almost as widespread as 4G. At last count, Three offered 5G in over 650 towns and cities, and to over 60% of the UK population – and both figures are likely to be even higher by the time you’re reading this.
So there’s a good chance you’ll be able to get 5G where you need it, meaning you’ll be able to tap into the highest possible speeds with these 3 mobile deals.
Three has been rated the UK’s fastest 5G network by Speedtest, in tests conducted in 2022, and echoed by data from 2023 and 2024. Similar 2024 tests from RootMetrics also found that Three’s 5G sped ahead of most rivals, as did Opensignal tests in September 2024.
To give you an idea of just how fast we’re talking, Speedtest found in the first half of 2024 that Three’s median 5G download speed was 255.23Mbps, which is higher than any rival, while Opensignal similarly found that Three’s average 5G download speed was better than rivals at 208.9Mbps. This has been made possible in part because Three has more 5G spectrum than any other UK network.
Three’s peak speeds also impress, with RootMetrics in the first half of 2024 recording a 95th percentile speed of 879.0Mbps for Three. That’s far higher than any other network in this test, with EE being a distant second at 709.0Mbps.
All that speed means you can download apps and files faster, stream video in higher quality, and game online more smoothly. In fact, just about anything that uses data will perform better on Three.
All Three customers with a phone or SIM plan get access to the network’s Three+ app, which includes offers from brands like Caffè Nero, Uber Eats, and Cineworld, among others. These can take the form of discounts and freebies.
Plus, the app includes competitions, and access to presale tickets for festivals, music gigs, and comedy events. New offers, deals, and events are added to the Three+ app frequently too, so there’s always something to enjoy.
You can access the Three+ app on both iPhone and Android, as a free download. So it’s accessible to every Three customer with a smartphone.
You can get 3 mobile deals with unlimited data, and these are available whether you’re going SIM Only, getting a phone on contract, or choosing mobile broadband or home broadband.
Better yet, Three’s unlimited data plans really are unlimited, with no speed limits or data caps when used in the UK.
That’s notable because many networks do have fair usage limits, even in the UK, but that’s not something you need to worry about on Three.
Three’s plans come with either free or cheap roaming in 163 global destinations. Pick a Value plan and you’ll get up to 28 days of free roaming (depending on the length of your plan), while with a Complete plan you’ll get up to 56 days. But even on Three’s most affordable Lite plans you can roam abroad for just £2 per day in Europe, and either £5 or £7 per day in many destinations outside Europe.
That all makes Three a great choice for frequent travellers, especially as those 163 roaming destinations include key places outside Europe like the US and Australia, whereas many networks limit you to European roaming unless you pay a high additional fee.
5G doesn’t cost extra on Three – it comes as standard. And not only that, but Three’s plans are very competitively priced.
With Three mobile deals you can get free, next working day delivery on phones, tablets, and broadband devices, so you won’t be left waiting long for your order.
Simply place your order before 8pm and it will be delivered by DPD the following working day (or in two working days for those in Northern Ireland or North of Scotland).
As well as home delivery, Three also offers next working day store collection – just make sure to bring some photo ID and the email order confirmation if using this service.
Three offers both Wi-Fi Calling and VoLTE (Voice over LTE) on all its plans as standard. This means you can make and receive calls – and send and receive texts – over Wi-Fi and 4G seamlessly.
The main benefit of this is that it means you can stay in touch in more places than on networks that don’t have these features, but call quality over Wi-Fi and 4G can also be higher, so the sound will be crystal clear.
One other perk of 3 mobile deals is that all Three’s phone and SIM plans let you tether – meaning sharing your phone’s internet connection with other devices.
This comes at no extra cost and the only limit is your data allowance – so if you choose one of the Three mobile deals with unlimited data then there will be no limit at all.
It’s simple to switch from another network when you grab one of these 3 mobile deals. In fact, most of the process can be handled with a simple text message.
Just text ‘PAC’ to 65075 from the number that you want to keep, and then – once your new Three SIM card is active – give the code you’re sent to Three, by filling in this form.
Three do make voucher codes and discount codes available from time to time. However, at the current time they only offer exclusive online 3 mobile deals to partners and run short-term sales.
Existing customers aren’t left out of all the Three deals. In fact, the network gives existing customers access to some exclusive deals to reward their loyalty.
Existing Three customer deals change over time, but often include discounts on phones, tablets, SIM Only plans, and even mobile broadband.
To access existing customer deals please login to your My3 Account, or download the Three app.
Yes, if you are eligible for an upgrade you will be able to access upgrade deals in your My3 account, or on the Three app.
We have handpicked the best 3 mobile deals on Three's network and put them all together for you to browse quickly and easily. They are constantly updated so you always get the heads up on the very latest deals and offers.
These Three mobile deals cover all the major product categories including mobile phones, SIM Only, home broadband, mobile broadband and tablets. You can quickly and easily switch between product categories to browse the best offers, or head over to our main product category pages where you can use filters to find the perfect 3 Mobile deals for you.
Note that while we’ve collected all the top deals for you, once you choose one, you’ll be dealing with Three directly. We take a small commission from Three, which is used towards the running of this website, but this does not increase the cost to you.
Sometimes you’ll be able to get free gifts when purchasing contract phones and other devices on Three.
The exact selection will vary and there won’t always be any plans with a free gift.
Transferring your number to Three is easy. Just activate your new Three SIM card, and then text ‘PAC’ to 65075 from the number that you want to keep.
You’ll then get a PAC (Porting Authorisation Code) within 60 seconds, which you can give to Three by filling in this form. Then your old number will be transferred on the date of your choice.
Yes, you can get Three mobile deals for businesses too, whether you want phones, SIM Only plans, mobile broadband, or tablets. And Three offers a price promise, so if you find a better deal on EE, Vodafone or O2, then Three will beat it by at least £1 per month.
