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.
The network once had prices so low you could get a better deal on this network for pretty much any phone. These days it's more of a mixed bag - it's not always the cheapest but it's often very competitive. And the trump card is that Three mobile is the only network to offer deals with unlimited data allowances.
Best 3 mobile deals arranged by handset
The best iPhone 7 deals on 3 mobile:
The new iPhone 7 is set to be another smash hit mobile phone thanks to further design enhancements. It's now waterproof, has a better screen and stereo speakers. The long-rumoured dropping of the headphone jack has become a reality, but there's an adapter in the box for your old cans, or there's a pair of lightning cable-friendly headphones in the box too. Memory capacity has been given a boost now, with the smallest models now starting at a much more robust 32GB.
iPhone 7 32GB | £79 upfront | Unlimited calls and texts | 8GB data | £34 per month
Three deals on the iPhone 7 are much cheaper than they were last month, and 8GB seems to be the magic number on this network. It's cheaper to get 8GB than it is to get 1GB at the moment. £79 bags you the phone and then it's £34 per month for the 8GB plan on Three with unlimited calls and texts. A good deal! Total cost over 24 months is £895.99
iPhone 7 32GB | £59 upfront | 12GB data | Unlimited calls and texts | £37 per month
If you need more 12GB and Three is your favourite network, this is the best deal out there on the iPhone 7 this month. £59 is a reasonable fee and then £37 per month for 12GB is competitive given the high prices on the other networks. Total cost over 24 months is £947
iPhone 7 32GB | £122.99 upfront | Unlimited data, calls and texts | £48 per month
If you want to get an iPhone 7 with unlimited data then this is the best deal out there at the moment. As you'd expect, the monthly fee is relatively high at £48 but that's actually very good value when you look at how much the other networks are charging for much less data. Total cost over 24 months is £1274.99
The best iPhone 7 Plus deals on 3 mobile:
Apple's larger iPhone 7 Plus is a premium upgrade over the regular iPhone 7. In addition to being waterproof, rocking stereo speakers and having an improved screen this year, the iPhone 7 Plus has a dual-lens camera with an incredibly clear zoom function for professional looking pictures.
iPhone 7 Plus 32GB | £149 upfront | 1GB data | Unlimited minutes and texts | £39 per month
Three was on a mission to offer lower costs for this phone, but that's not happened here. For this deal, you get the iPhone 7 Plus for a fairly high cost upfront and then you pay less monthly for 1GB data and unlimited texts - a decent deal if you want the lower end of the data spectrum on Three. Total cost over 24 months is £1085
iPhone 7 Plus 32GB | £149 upfront | 12GB data | Unlimited calls and texts | £45 per month
If you like the sound of 12GB rather than a single gigabyte then this deal might be better for you - in fact, it really should be the first place you look. Yes, it's expensive but it's a strong choice with a large amount of data, netting you Apple's best phone and a good slug of data to play with too. Total cost over 24 months is £1229.
iPhone 7 Plus 32GB | £88.99 upfront| Unlimited minutes and texts | 30GB data | £54 per month
This is definitely one the best iPhone 7 Plus deals for near-unlimited data right now, although it's a bit higher this month. There's an impossible amount of data on offer to help you get the most out of the larger phablet screen, and while the phone will set you back a little bit each month there's a low upfront cost and... that's the end of the data scares. Total cost over 24 months is £1384.99
The best iPhone SE deals on 3 mobile:
The iPhone SE looks and feels exactly the same as the iPhone 5S. But instead of sporting two-year-old hardware it's fully up to date, with a super-fast CPU and graphics, and the 12MP iSight camera straight out of the iPhone 6S. It's a modern iPhone in the shape of an old iPhone, for people who like the old iPhones but want more up-to-date hardware. Three is now running contracts from £28 per month.
iPhone SE 16GB | FREE upfront | Unlimited calls and texts | 1GB data | £25pm
Three also has some top iPhone SE deals this month, kicking off with this offering which is asking for just £25 per month over two years in return for a free 16GB iPhone SE. There's unlimited calls and texts, and 1GB of data to keep you going every month. The total cost of this deal over 24 months is £600
iPhone SE 16GB | £59.99 upfront | Unlimited calls and texts | 1GB data | £22pm
Fancy spending less each month and saving over the two years of your contract? Then this is the iPhone SE deal for you. You'll need to part with a penny shy of £60 upfront, but from there you're laughing with a £22 monthly fee, 1GB of data and unlimited calls and texts. Total cost over 24 months is £587.99
iPhone SE 64GB | FREE upfront | Unlimited calls and texts | 1GB data | £29pm
Spend £8 more per month though and you'll get your hands on a free 64GB iPhone SE with 1GB of data. With unlimited calls and texts, and that low monthly outlay, this is a win-win iPhone SE deal. The total cost of this deal over 24 months is £696
The best Samsung Galaxy S7 Edge deals on 3 mobile:
The Samsung Galaxy S7 Edge is a a good deal different to the S6 Edge we saw last year. It's bigger, it's better and there's a real reason to go for it over the smaller Galaxy S7. At 5.5-inches it's a little larger than the S7 but a tad smaller than the Galaxy Note 5 or the S6 Edge+ - it's the perfect size for those who covet the big screen but don't have the big hands to match, thanks to it being curved nicely into the chassis.
Samsung Galaxy S7 Edge | £74.99 upfront | Unlimited calls | Unlimited texts | 1GB data | £30pm
This is your entry-level look at Three, with the lowest amount of data and a sub-£100 upfront cost to keep things ticking over. It's not going to suit everyone (although the price has dropped this month by a whole pound over the lifetime of the deal), but if you're wedded to the numerical network, hanker after this phone and don't want to spend a lot, this is your choice. Total cost over 24 months is £794.99
Samsung Galaxy S7 Edge | Free upfront | 8GB data | Unlimited calls and texts | £35 per month
One of the best Samsung Galaxy S7 deals this month is on Three. Thanks to that curved edge screen, which frankly ruins other phones, the S7 Edge is a phone you'll never tire of. The internal spec shows it's got more than just looks too as it's still a sharp performer. As for this contract, you're looking at a really strong deal as we're used to seeing 5GB deals go for well over £1000 - yet this offers 8GB instead! You can make the lifetime cost cheaper if you pay a little upfront, but we've gone for the 'free phone' version here. Total cost over 24 months is £840
Samsung Galaxy S7 Edge | Free upfront | Unlimited calls | Unlimited texts | 12GB data | £41pm
This is a decent amount of data per month and for the upfront cost it's not the worst barrier to entry. £41 per month isn't the highest cost in the world (although you can get that down to £36 if you pay a bit upfront), and it'll give you a decent slug of bytes to play with. Do take a look at our deals comparison engine though - as mentioned, there are some good 12GB deals for a higher upfront cost and less per month if that's your poison. Total cost over 24 months is £984
The best Samsung Galaxy S7 deals on 3 mobile:
The Samsung Galaxy S7 has been around for a few months and is still the cheaper one of the 'best phone in the world' duo, with the S7 Edge a tasty - if more expensive - alternative. As is the techradar way we've found all the best deals from Three and their partner stores online for this high end phone -and the good news is that while we were expecting the Galaxy S7 deals to be very expensive to start with, it's already come down a little in price - the UK market is very competitive, and prices do alter regularly. So if you're thinking about buying one it might be best to go early rather than wait a while – prices could easily go up in a few weeks.
Samsung Galaxy S7 | £49.99 upfront | Unlimited calls | Unlimited texts | 1GB data | £28pm
Three is never the cheapest places to find the best deals for phones these days, but at least it's started offering some better tariffs on the Galaxy S7 after months of high prices. Here you can get the new phone for a bit of cash upfront and with not TOO high an outlay each month - compared to the iPhone 7 it's a lot cheaper. Total cost over 24 months is £721.99
Samsung Galaxy S7 | £19.99 upfront | Unlimited calls and texts | 8GB data - £30pm
It's Three on the march again in the best deals this month, offering a decent 8GB of data with this fancy phone from Samsung. There's only a small upfront cost to get your hands on this, and overall it's a strong choice for that data. This deal is for the very nice black version too, so you'll be the talk of the town... if your town literally has nothing else going on. Total cost over 24 months is £739.99
Samsung Galaxy S7 | £29.99 upfront | 12GB data | 300 minutes and unlimited texts | £36 per month
This is a large slice of data to be playing around with per month. While the minutes are low and overall cost slightly higher, this is the best we could find for a huge slug of bytes, and you're getting them on one of the best phones around at the moment. Take a look at the comparison chart below to shop around for similar deals if you want to see if there's something a touch more applicable to you. Total cost over 24 months is £893.99
The best Xperia XZ deals on 3 mobile
Sony has produced remarkable phone with one of the market's leading cameras and fantastic build quality. The 5.2-inch screen is 1080p and looks fantastic, and there's plenty of power underneath the gorgeous exterior to make the Sony Xperia XZ one of the most powerful handsets on the market - and it's comfortable to hold as well, despite the large screen size.
Sony Xperia XZ | £49.99 upfront | 600 mins | Unlimited texts | 1GB data | £29pm
This Xperia XZ deal gives you 600 minutes and unlimited texts each month, along with 1GB of data. The monthly allowances may be modest, but so too is the monthly cost, as you only need to part with £29 each month, making this an affordable way to get your hands on Sony's latest. You do need to pay upfront with this deal, but £49.99 isn't too steep considering the quality of the handset. Total cost over 24 months is £745.99.
Sony Xperia XZ | Free upfront | Unlimited mins | Unlimited texts | 2GB data | £33pm
This deal gives you a bit more freedom, as the talk time has been boosted to unlimited minutes, and the 4G data allowance has been doubled to 2GB, while texts remain all-you-can-eat. You don't need to pay any upfront cost, and the monthly payments have dropped by £2 a month since February. Total cost over 24 months is £792.
Sony Xperia XZ | Free upfront | Unlimited mins | Unlimited texts | 8GB data | £33pm
Now this is a very tempting deal for the Sony Xperia XZ on the Three network. You get the handset for no upfront cost, unlimited minutes and texts and a very nice 8GB of 4G data each month, which should be more than enough for most people. Total cost over 24 months is £792.
