Three mobile has for a long time been well known in the UK for offering good deals, especially for customers looking for some seriously big data bundles. In the early days, the network was blighted by poor reception in many areas but these days Three mobile doesn’t have any such issues and its prices can be stellar.
So take a look at our comparison tool to see what you can get for your money with Three. And below that we’ve also handpicked the best the network has to offer on flagship handsets such as the iPhone XR and Samsung Galaxy S10.
And if you’re perfectly happy with your current handset but are at the end of your contract, then we heartily recommend that you consider the 100GB Three SIM only deal for £20 per month

Price comparison chart
Three mobile deals on the Samsung Galaxy S10
Samsung’s newest release, this phone is rocking a completely flat, notch-less screen with a pin hole camera, giving it a unique style. Whether it’s the triple cameras on the back, fast processor or reverse charging, there is a lot to love here.
Samsung Galaxy S10 | £79 upfront | All-you-can-eat data | Unlimited minutes and texts | £57pm
We know, we know. Sometimes only unlimited data will do. Well you’re going to have to go for Three then, aren’t you. The monthly payments for unlimited Netflix binging, heavy Facebook scrolling and Spotify streaming through the night away from Wi-Fi are on the high side, but at least there’s not too much to spend upfront. Total cost over 24 months is £1,447
Samsung Galaxy S10 | £79 upfront | 1GB data | Unlimited minutes and texts | £41pm
Keeping the same upfront cost as above but dropping the monthly cost all the way down to £41, this is the most affordable way to get the S10 on Three. Of course, you will be capped at 1GB of data so if you’re a heavy data user, this might not be the contract for you. Total cost over 24 months is £1,063
Samsung Galaxy S10 Plus | £79 upfront | All-you-can-eat data | Unlimited minutes and texts | £61pm
Okay, so the S10 Plus is already an expensive device so going for all-you-can-eat data might seem crazy. But, there is an argument that if you’re going to pay a lot for a phone you might as well go all out. If you’re happy to big on your new phone deal we can’t think of any better way to do it. No data caps on Samsung’s top device. Total cost over 24 months is £1,543
Samsung Galaxy S10 Plus | £79 upfront | 1GB data | Unlimited minutes and texts | £45pm
Unlimited data isn’t for everyone, in fact, a lot of people would rather pay a lot less and take a big cut on data, if that’s you then this might be a deal you can get on board with. Keeping the £79 upfront fee and dropping the monthly cost down to £45, this is one of the cheapest Three S10 Plus deals out there. Total cost over 24 months is £1,159
Three mobile deals on the Samsung Galaxy S10e
Samsung’s brand new budget flagship, the S10e features high-end specs for an affordable price. If you want the best Samsung has but don’t want to have to pay through the roof to get it, this is the way to go. With all of the same features as the S10 with a few cutbacks, this is a high-end phone with mid-range pricing.
Samsung Galaxy S10e | £79 upfront | Unlimited data | Unlimited minutes and texts | £52pm
There’s a small part in all of us that wants to stream, download and scroll all day and to those who want to embrace that side of themselves, we say go for an unlimited data contract. Coming in at £79 upfront and £59 a month you really don’t even have to pay too much to get it either. Total cost over 24 months is £1,327
Three mobile deals on the iPhone XR
The iPhone XR hits a sweet spot between high tech and reasonable pricing. It looks a lot like its more powerful brethren – both in appearance and on the spec sheet – and boasts a glorious 6.1-inch Liquid Retina display and A12 Bionic chipset without a £1,000 price tag.
iPhone XR | £49 upfront | All-you-can-eat data | Unlimited minutes and texts | £58pm
Well this is a lot more affordable than we thought it would be. Three was always going to be the network offering all-you-can-eat data, but we assumed the monthly price would be waaaaaaay over £50. The upfront spend is reasonable too. So if it’s all the data you need, it’s all the data you’ll get with Three. Total cost over 24 months is £1,441
iPhone XR | £49 upfront | 1GB | Unlimited minutes and texts | £43pm
Where there is absolutely no doubt around Three’s prowess over the unlimited data scene, it seems like they struggle a bit more when it comes to the cheaper end of the spectrum. If you’re looking to get a Three contract at its lowest price it will cost you around £43 a month. But, you will be capped at 1GB of data, we would advise just sticking to Three for unlimited data options. Total cost over 24 months is £1,081
Three mobile deals on the Samsung Galaxy S9
OK, so the Samsung Galaxy S9 doesn’t make massive strides on the S8, but that doesn’t mean it’s not still one of the premier Android phones on the market. The cameras in particular are awe inspiring and tangible improvements have been made to the biometrics and position of the fingerprint scanner.
Samsung Galaxy S9 | £49 upfront | All-you-can-eat data | Unlimited minutes and texts | £47pm
Three may not have the pricing fire power of the other networks, but it does have a handy trick up its sleeve to persuade you to grab your new S9 contract with the numerical network. This tariff gives you absolutely unlimited data – the kind of volume other networks just can’t reach.Total cost over 24 months is £1,1177
Samsung Galaxy S9 | £49 upfront | 4GB data | Unlimited minutes and texts | £35pm
On the complete opposite end of the spectrum to the deal above, this contract has a much lower data point. Coming in at 4GB of data for £35, this is on the higher end of S9 costs, but if you really want to be on Three without spending AYCE prices, this is the offer we would suggest going for. Total cost over 24 months is £889
Three mobile deals on the iPhone XS and iPhone X
Oh gosh, Apple went and did it. After years upon years of incremental upgrades, it finally made something special to celebrate the 10th anniversary of the iPhone. For the iPhone X it has dropped the bezel altogether, while the 5.8-inch Super Retina HD is scarily good – and then it tweaked things a year later for the XS. Marvellous!
iPhone XS | £99 upfront | All-you-can-eat data | Unlimited minutes and texts | £65pm
You know how the expression goes ‘big data phone contracts cost the world but they make your life so much better’. Okay, so no one has ever said that but it is true. You do have to fork up a big ol’ £65 a month and £99 upfront, but once you do you’ll have unlimited data on one of the best phones in the world, sounds fun right? Total cost over 24 months is £1,659
iPhone X 64GB | £49 upfront | All-you-can-eat data | Unlimited minutes and texts | £54pm
If you want unlimited data on the iPhone X then Three was always going to be your go-to network. We can’t imagine you’d even be considering this if you wanted something cheap – all that streaming, surfing and downloading comes at a cost. It might be high but it is the price you’ll have to pay for unshackled data use. Total cost over 24 months is £1,345
Three mobile deals on the Samsung Galaxy Note 8 and Note 9
Samsung has now well and truly put the flaming memory of the Note 7 behind it. If the Note 8 was exceptional (6.3-inch infinity display and 6GB RAM), then the Samsung Galaxy Note 9 is even bigger and better (6.4-inch infinity display and 8GB RAM). If you want the best big screen Android phones on the market, then look no further.
Samsung Galaxy Note 9 | Three | £49 upfront | All-you-can-eat data | Unlimited minutes and texts | £55pm
If you honestly, positively, absolutely need unlimited date each month, then Three is your only option when it comes to Galaxy Note 9 deals. The jump in price is quite significant, mind – so do make sure that it’s essential to have limitless Netflix, Spotify and downloading access. Total cost over 24 months is £1,399
Samsung Galaxy Note 9 | Three | £49 upfront | 1GB | Unlimited minutes and texts | £39pm
On the complete opposite end to All You Can Eat data, Three also does brilliant small data contracts. These allow you to save money on your bills by taking a drop in your data allowance. So if you really need a Three contract but don’t want to pay tonnes to get it, this is the way to go. Total cost over 24 months is £985
Three mobile deals on the iPhone 8
Thanks to the spectacle that was the iPhone X launch, the reception for the iPhone 8 was a little bit flat. Perhaps unfairly – it improves on the iPhone 7 with wireless charging and an improved camera. Plus, it’s quite a bit cheaper. So if you’re looking for the best iPhone but balk at the iPhone X expense, try the 8 on for size instead.
iPhone 8 64GB | £36.99 upfront | All-you-can-eat data | Unlimited calls and texts | £46pm
In this contracts never-ending price rises and falls, it is currently…well somewhere in the middle, anti-climatic right? Costing £46 a month and £36.99 upfront this is a contract that provides not only the obvious – unlimited data – but also gets it for you at a relatively affordable price. Total cost over 24 months is £1,140.99
Three mobile deals on the Samsung Galaxy S8
There’s no doubt that the Samsung Galaxy S8 is a fantastic phone. The lightning fast chip-set and abandonment of a large bezel around the screen makes it the premier Android experience. And now that the S9 is here, it’s no longer even that expensive.
Samsung Galaxy S8 | £29 upfront | All-you-can-eat data | Unlimited minutes and texts | £46pm
Unlimited data really isn’t that expensive on the S8. For just £37 a month and a small upfront cost of £49 you can get the device with absolutely no caps on your data, you can go absolutely wild with how much data you consume, perfect for those who use their phones constantly. Total cost over 24 months is £1,133
Three mobile deals on the Google Pixel 3 and 3 XL
The Google Pixel 3 and 3 XL are relatively new devices on the flagship scene but they have very quickly become two of our favourites. Powerful processors, loud speakers, but most importantly they have what is arguably the best cameras you can get on a phone right now.
Google Pixel 3 XL | £19.99 upfront | Unlimited data, minutes and texts | £49pm
Want unlimited data? Well Three is the way to go and this looks like it is the best Google Pixel 3 XL unlimited data contract floating around right now. It is quite expensive but that is the price you pay to have no caps on your data usage. Total cost over 24 months is £1,195.99
Google Pixel 3 | £29 upfront | All-you-can-eat data | Unlimited minutes and texts | £49pm
Three knows that it’s the only major network currently offering unlimited data deals. Which only makes us more impressed by the AYCE deal that it has conjured up on the Pixel 3. You do have to pay quite a bit a month but at least the upfront is still low! Total cost over 24 months is £1,205
