We’ve partnered with Three and have access to 3 mobile deals that you won’t find elsewhere – even on Three’s own site. These deals cover SIM Only plans, mobile phones, home broadband, and mobile broadband, so almost every product category offered by Three.
When browsing our site, the exclusive Three mobile deals are clearly labelled, with ‘exclusive deal’. In the current cost of living crisis, these discounted 3 mobile deals will save you a considerable amount of money.
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.
For a closer look at some of the best Three mobile deals and devices across all categories, read on. Then further down you’ll find more information on Three itself – and why it’s a great network choice.
The best Three mobile SIM Only deals currently include a number of exclusives, such as 25GB of data on a 12-month contract for just £8 per month. If you shop with Three direct, those same allowances will cost you £16 per month.
If you’re a big data user then you can similarly get 120GB for £12 per month (compared to £18 from Three direct) and an unlimited data deal for £20 per month (compared to a standard price of £27).
These Three mobile deals on SIM Only are all 12-month plans, and all also include unlimited minutes and texts. But what if you don’t need much data? We’ve got you covered there too, with a 3GB 12-month plan for just £5 per month.
All of the exclusive 3 mobile deals on this page (and the deals elsewhere on our site) are available to new Three customers, so you don’t need to be with Three already to get an excellent offer.
The iPhone 15 Pro is one of the most popular phones on the planet, and right now you can get it with a hefty 150GB of data for just £38 per month plus £50 upfront with one of these 3 mobile deals. That includes unlimited minutes and texts too, and is on a 36-month contract.
If you’re more into Android then you can get the same allowances with a Samsung Galaxy S23 Ultra for £45 per month, plus £65 upfront. There’s also a deal on the cutting-edge Google Pixel 8 Pro for £38 per month plus £55 upfront, which again gets you 150GB of data on a 36-month plan.
Don’t need such a high-end phone? Then how about the standard Samsung Galaxy S23 with 150GB of monthly data for £34.50 per month and £30 upfront. That again is a 36-month contract and includes unlimited minutes and texts, making it one of the best Three deals. The iPhone 15 can be had on the same terms for £33 per month and £30 upfront.
Looking for something more affordable? Why not check out the brilliant Google Pixel 7a for £22 a month with 150GB, or the Samsung Galaxy A34 5G for just £20.22 a month.
You’ll find a number of great Three mobile iPhone deals here, which currently includes exclusive offers on the iPhone 15, the iPhone 15 Plus, the iPhone 15 Pro, the iPhone 15 Pro Max, and the iPhone 14 range.
In every case with these Three mobile iPhone deals you’re getting a hefty 150GB of monthly data, with prices starting as low as £30.50 per month.
We’ve also got exclusive Three mobile Samsung deals for a variety of the latest devices, including the Samsung Galaxy S23, the Samsung Galaxy S23 Plus, the Samsung Galaxy S23 Ultra, and cheaper models like the Samsung Galaxy A14.
You can get the last of those Three mobile Samsung deals for just £18 per month plus £15 upfront, and that will come with 150GB of data on a 36-month contract.
Right now, whether you want 5G home broadband or 4G home broadband you can get it free for three months with the best Three deals.
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 4G+ MiFi on a 24-month contract with unlimited data for £22 per month, but with the first six months being half price, so you’ll only pay £11.
That’s with no upfront cost, and if you don’t want to be tied in to such a long contract, you can get it on a 12-month plan with a £19 upfront cost for £26 per month, reduced to £13 per month for the first six months. That saves you £78 over the life of the contract.
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 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 588 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 Ookla, in tests conducted in 2022, and echoed by data from 2023. Similar 2023 tests from RootMetrics also found that Three’s 5G sped ahead of rivals, as did Opensignal tests in April 2023.
To give you an idea of just how fast we’re talking, Ookla found in 2023 that Three’s median 5G download speed was 275.85Mbps, which is higher than any rival, while Opensignal similarly found that Three’s average 5G download speed was better than rivals at 237.7Mbps. 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 2023 recording a 95th percentile speed of 813.6Mbps for Three. That’s far higher than any other network in this test, with EE being a distant second at 436.9Mbps.
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, Moonpig, 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.
As well as the Three+ app, Three also offers a dedicated app for viewing your usage and managing your account.
Simply dubbed ‘Three’, this app lets you view and pay bills, set spend caps, top up, see when you’re eligible for an upgrade, view personal offers, see how much of your monthly allowances you’ve used, purchase add ons, and access details of new devices and accessories, as well as finding help and answers to queries.
As with Three+, the Three app is available on both iOS and Android.
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.
As well as optionally coming with unlimited data, all Three mobile deals for phones and SIM-only include unlimited calls and texts, so you never need to worry about how much you’re texting or talking.
Three’s plans come with either free or cheap roaming in 71 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 £5 per day in many destinations outside Europe.
That all makes Three a great choice for frequent travellers, especially as those 71 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. Not all networks can say the same, so that’s a reassuring perk to have. 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.
With 3 mobile deals you’re sure to be able to find a plan to suit, because on top of offering a wide range of different data allowances, Three also offers three different types of plans, so you can choose the one with the perks you need.
There are Lite plans, which are the most basic and affordable, but still come with 5G, unlimited calls and texts, and access to the Three+ rewards app. Then there are Value plans, which add free roaming (for up to 28 days), along with a Paramount Plus subscription for half the duration of the plan, and an extended warranty of up to three years when taken with a device.
Finally, there are Complete plans, which are like Value plans but come with up to 56 roaming days, give you Paramount Plus for the length of the contract, and include screen repair when taken with a 24-month device plan.
For more details about Three’s plan types, check out our Three plans guide.
Select Three mobile deals also come with Paramount Plus, for either half the length of the plan or the full duration.
Paramount Plus is a streaming service packed full of shows and movies, such as Yellowstone, South Park, and Top Gun: Maverick. It usually costs £6.99 per month, so it’s a great perk.
If you’re considering a 4G or 5G home broadband plan, it’s good to know that Three has a 30-day money back guarantee. So if you decide 4G or 5G home broadband isn’t for you – or that Three’s coverage or speeds aren’t good enough in your home – you can get a full refund within the first 30 days of taking out one of these 3 mobile deals.
That makes trying 5G or 4G home broadband on Three completely risk free.
Three UK has won all sorts of awards over the years, with a recent example being that it was rated the UK’s fastest 5G network by Ookla in both 2023 and 2022. It was also the Uswitch Best Network for Data Winner 2022, and won the Best Network for Data and Best Network for Roaming awards at the 2021 Uswitch Awards.
So you can be assured that you’re on a great network if you grab one of these Three mobile deals.
Three has a recycling scheme which will pay you for your old device, so you can offset some of the cost of an upgrade, while ensuring your old phone gets some more use.
At the time of writing, you can save up to £950 when you trade in select iPhone models, so there’s big money to be made here, and Three will process the payment within 24 hours, so you won’t be left waiting long.
So as good as many 3 mobile deals already are, this can make them even more affordable.
If you refer a friend to Three and they grab one of the Three mobile deals, then both you and they will get up to £40. The exact amount will depend on the type of plan they buy, and which phone they get if they’re purchasing a new phone.
There’s no limit to how many referrals you can make either, so you could make a lot of money out of it if you have enough interested friends.
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 doesn’t lock any of the devices it sells, so if you grab a smartphone on one of these Three mobile deals you’ll be free to use it with any other network as well.
And while you can’t get Three mobile deals SIM-free, you can buy phones outright from the network so you’re not tied into a contract, and then you’re free to use these phones with another network.
If you ever want in-person support, there are no shortage of Three UK stores to visit. Check out our Three store locator for the full addresses and phone numbers of them all.
As well as stores, there are plenty of other ways to get in touch with Three customer service if you ever need help or support after signing up for one of these Three mobile deals.
The simplest way is to call 333 from a Three phone, but there are other numbers and other options too, including live chat. For full details, head to our Three customer service page.
If you grab one of these Three mobile deals then you’ll likely have a monthly plan and not need to worry about topping up, but if you do need to top up, that’s simple too.
You can do so online, over the phone, or with the Three app. For full details, check out our Three top up guide.
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.
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. But for example, at the time of writing it was possible to get Samsung Galaxy Buds 2 Pro and a Starter Pack for free with the Samsung Galaxy Z Fold 5. Those freebies are valued at £318, so it’s worth keeping an eye out for offers like that.
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.
