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 X and Samsung Galaxy Note 8.
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 30GB Three SIM only deal for less than £20 per month - it won the Mobile Choice Consumer Award 2017 for Best Phone Deal.
The best iPhone X deals on Three mobile:
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 if you tuned into the launch event and liked the look of Animojis, well there's that as well!
iPhone X 64GB | £71.99 upfront | 8GB data | Unlimited minutes and texts | £58pm
Three has gone from hero to zero on iPhone X deals. For a while there, it was leaving the other networks in its wake. But now it just can't compete. But we know that some of you are big fans, so we thought we'd still show the most affordable deal you can get. Here you get 8GB of data - that should be plenty of Spotify streaming and internet searching for most people. Total cost over 24 months is £1463.99
iPhone X 64GB | £79 upfront | 100GB data | Unlimited minutes and texts | £72pm
If you really really want unlimited data, then just take a quick second look at this Three deal. You're 'limited' to 100GB a month but will save a couple of hundred pounds over the two year contract. We can barely see how you'd use this much data, so well worth considering instead. The upfront cost is reasonable, but the monthly payments have unfortunately just increased by a few pounds. Total cost over 24 months is £1808
iPhone X 64GB | £79 upfront | All-you-can-eat data | Unlimited minutes and texts | £79pm
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. Only you will know whether you really need all-you-can-eat data. Total cost over 24 months is £1975
The best iPhone 8 deals on Three mobile:
Thanks to the spectacle that was the iPhone X launch (see above for more of that splendour), 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 | £49 upfront | 30GB data | Unlimited calls and texts | £45pm
As is so often the case, Three comes is decent value. But only when you begin to crank up the data allowance. Forget lower data deals on the numerical network, because £45 a month is now pretty much the cheapest way to go anyway. 30GB will almost certainly cater for all your streaming and surfing needs each month. Total cost over 24 months is £1129
iPhone 8 256GB | £99 upfront | 1GB data | Unlimited calls and texts | £45pm
The iPhone 8 starts with 64GB instead of the the 32GB of the iPhone 7, but that's still not going to be enough room for the tunes, snaps and videos some people will want to store on their phone. This Three deal is one of the cheapest ways you can currently get the model with more memory. Total cost over 24 months is £1179
iPhone 8 256GB | £85.99 upfront | 50GB data | Unlimited calls and texts | £49pm
This is for people who mean serious business; for those who really want to have their cake and eat it. A Three tariff that provides a massive 50GB of data per month, for Apple's MASSIVE 256GB iPhone 8. It's obviously a lot of cash, so do ensure that you really need all this data and memory. Total cost over 24 months is £1261.99
The best Samsung Galaxy S9 deals on Three:
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 | £79 upfront | 4GB data | Unlimited minutes and texts | £43pm
Three isn't exactly what we'd call 'cheap' when it comes to the Samsung Galaxy S9. But if you like the numerical network and have heard good things about the perks you get from its Wuntu app, then this is as affordable as it gets right now. Total cost over 24 months is £1111
Samsung Galaxy S9 | £79 upfront | 12GB data | Unlimited minutes and texts | £48pm
We did just about prefer this deal to the S9 tariff directly above. But it's just gone up by £3 per month, so now it costs £8 more a month. That gets you triple the data. Far more comfortable if you tend to stream Spotify and videos away from the Wi-Fi regularly. Total cost over 24 months is £1231
Samsung Galaxy S9 | £79 upfront | 100GB data | Unlimited minutes and texts | £57pm
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. Get a Three S9 deal and it will throw in 12 months of Netflix for free - that's over £70 worth. This tariff gives you an almighty 100GB of data - the kind of volume other networks just can't reach. Total cost over 24 months is £1447
The best Samsung Galaxy Note 8 deals on Three mobile:
Sssssshhhhh! Don't mention the Samsung Galaxy Note 7 and its troublesome little overheating problem. The awesome Galaxy Note 8 has helped as forget all about that little fiasco thanks to its vast 6.3-inch infinity display and razor sharp 6GB Ram. If you want the best big screen Android phone on the market, then look no further.
Samsung Galaxy Note 8 | £9.99 upfront | 4GB data | Unlimited minutes and texts | £42pm
Phew! For a while there retailers stopped offering the Samsung Galaxy Note 8 with anything less than a 30GB data allowance. Buymobiles is back in the game though, which means things have got much more affordable again on the numerical network. This is one of the cheaper deals out there from anybody - not just Three - right now. Total cost over 24 months is £1017.99
Samsung Galaxy Note 8 | £9.99 upfront | 30GB data | Unlimited minutes and texts | £52pm
Spend an extra tenner a month and you can crank the data up to a bountiful 30GB every month. That's a super amount to stream ,surf and download with - you'll really struggle to max it out. And this Note 8 tariff is loads cheaper than the all-you-can-eat rate below.. Total cost over 24 months is £1257.99
Samsung Galaxy Note 8 | £79 upfront | Unlimited data, minutes and texts | £66pm
Well helloooooooooo big spender! We know you're not going to be deterred by our warnings of the price and suggestions of going for 30GB instead - you want all-you-can-eat, and you want it now. Three is the only network that can offer uncapped data, so you have no option but to sign up with this deal. This has just fallen by almost a tenner a month though, so a little less flashy than it used to be. Total cost over 24 months is £1663
The best iPhone 7 deals on Three mobile:
The new iPhone 7 is another smash hit mobile phone from Apple 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. Memory capacity has been given a boost now, with the smallest models now starting at a much more spacious 32GB.
iPhone 7 32GB | £49 upfront | Unlimited calls and texts | 4GB data | £36 per month
They say that all good things must come to an end, and that's certainly the truth when it comes to iPhone 7 deals on the Three network. You only get 4GB of data per month for a not unsubstantial amount of money over the two years. We'd simply recommend that you go for another network instead. Total cost over 24 months is £913
iPhone 7 32GB | £49 upfront | Unlimited calls and texts | 30GB data | £45 per month
This is our favourite big data deal for Three - but that doesn't exactly make it cheap. The price of the handset is £50, which isn't bad. But the monthly bills aren't ideal. Total cost over 24 months is £1129
Best Samsung Galaxy S8 deals on Three mobile:
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 | £24.99 upfront | 4GB data | Unlimited minutes and texts | £37pm
This is currently the cheapest way to buy the Galaxy S8 on Three, but it just got waaaaaaaaay more expensive. It's nowhere near to mounting a serious challenge to the other networks for sheer low prices. Total cost over 24 months is £912.99
Samsung Galaxy S8 | £49.99 upfront | 30GB data | Unlimited minutes and texts | £45pm
Wow! This is so much more expensive than what you used to be able to get on Three for 30GB of data. It used to be the network for big data deals, but has somewhat lost its mojo for the time being. Total cost over 24 months is £1129.99
Samsung Galaxy S8 | £79 upfront | 100GB data | Unlimited minutes and texts | £58pm
Unless you really really really need this much data, look away from Three now. It's gone from hero to zero on big data plans on the Samsung Galaxy S8, and we just can't quite understand why. But no other major network currently offers this sheer amount of data, so you don't have much choice if it's what you really need.. Total cost over 24 months is £1471
The best iPhone SE deals on Three mobile:
The iPhone SE looks and feels exactly the same as the iPhone 5S. But instead of sporting two-year-old hardware it's been updated, with a faster 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.
iPhone SE 32GB | £19 upfront | Unlimited calls and texts | 2GB data | £20pm
You'll pay less than £20 upfront for this iPhone SE deal direct from the Three network, and from there you're laughing with a £20 monthly fee, 2GB of data and unlimited calls and texts. You'll end up spending just less than £500 over the two year contract AND have the warm cosy feeling of buying directly from the network. Total cost over 24 months is £499
iPhone SE 32GB | £19 upfront | Unlimited minutes | Unlimited texts | 30GB data | £35pm
Three used to be 'da man' for big data deals on the iPhone SE, but no longer. This is now the best it can offer. We don't think that anybody should be paying this for such a budget phone, even if it is for a colossal 30GB of data each month. The total cost of this deal over 24 months is £859
