So if you want an iPhone 6S and you want the cheapest possible deal without going below 1GB data, this is still the best deal out there.

iphone 6 deals on Three

iPhone 6S 128GB | £10 upfront (with PAY40DAY code)| Unlimited calls and texts | 24GB data - £32pm
And if you want a massive, MASSIVE 24GB of data with the iPhone 6S for a good price, this is a really strong deal. It's very little to pay upfront and has a lower cost than many other deals on this page per month. Honestly you should probably go for this deal over all the the ones above and below if you're at all worried about data allowance - it's tremendous value. Total cost over 24 months is £778

iPhone 6S 32GB |  £25 upfront| Unlimited minutes and texts | 3GB data | £25.99 per month
Good news: this is only for the 32GB variant of the phone, so it's worth checking out given it's in the same league as most of the others here. If you're after a few more bytes but don't want to break the bank, this is the best 3GB deal out there at the moment - and cheapest overall too! Total cost over 24 months is £648.76

iPhone 6S 32GB | Free upfront | Unlimited calls and texts | 5GB data | £30.99 per month
If you're after a few more bytes to play with per month, then this deal will take you where you want to go. There's also no upfront cost, true, and without that you're on a flat rate per month and getting a decent 5GB to play with. Total cost over 24 months is £743.76

iPhone 6S 32GB | £9.99 upfront | Unlimited calls and texts | 10GB data | £40.99 per month
If having lots of data is what you need above all else, this is the best deal we can find for the iPhone 6S. There's an upfront cost to play with but the monthly tariff isn't that bad for phone of this calibre - in fact, that's a pretty hefty whack of data for the price (as long as you're wedded to EE). Total cost over 24 months is £993.75

iPhone 6S 32GB | £75 upfront | Unlimited calls and texts | 3GB data | £26.50pm
If you want a 32GB iPhone 6S on O2 with a decent-ish amount of data, this is the cheapest we could find. It's a relatively large amount upfront and it's got the least data we could find on O2 for this kind of value, if you're wedded to the bubbly network. The cost over 24 months is £840

iPhone 6S 32GB | £29.99 upfront (with code 10OFF) | Unlimited calls and texts | 5GB data | £35pm
If you want a 32GB iPhone 6S on O2 with a stronger amount of data, this is the cheapest we could find. It's a small amount upfront with the code and while it's not cheap for the monthly tariff it's the top offer for this model and data combo that we could find on O2, if that's your poison. The cost over 24 months is £869.99

iPhone 6S 32GB | £9.99 upfront (with code 10OFF) | Unlimited calls and texts | 10GB data | £40pm
This is the kind of deal that the person who worries about downloading on the go should head for: it's less than £1000 over the course of the contract (well, you are buying an iPhone) and gives peace of mind with that whack of data on offer. In short, if you want to go with O2 and need some bytes, here you go... The cost over 24 months is £969.99

Best iPhone 6S deals on Vodafone

Offers extras like Spotify and Sky Sports

iPhone 6S 32GB | £99 upfront (with 10OFF code) | 1GB data | Unlimited minutes and texts | £24 per month
This is the cheapest deal for this phone thanks to a great, low-cost per month. The upfront cost is a little on the steep side, but you're getting the higher-capacity model to play with - and you get a mega-low tariff per month. Overall, a good deal that the thrifty on Vodafone will enjoy.  Total cost over 24 months is £675

the best iphone 6s deals

iPhone 6S 32GB | £74.99 upfront (with 10OFF code) | Unlimited calls and texts | 3GB data | £28pm
This deal will appeal more to those people who want a lot more data and don't mind paying some upfront - it's a bit more monthly, but you're not paying as much to start with to help offset that. So that's a lower upfront cost with 3GB data, and while it works out a bit more expensive than some deals over the two year contract it's more data to play with. Total cost over 24 months is £746.99

Best iPhone 6S deals on Three

The network with unlimited data

iPhone 6S 32GB | £71.99 upfront | Unlimited calls and texts | 1GB data | £30pm
Sadly Three hasn't regained its decent deals for the 6S this month, harking back to the days where it was hard to find good deals for Apple's 2015 phone on this network. The upfront cost isn't too bad and the monthly cost is digestible for 1GB data - but check out the next deal for a pound extra. Total cost over 24 months is £791.99

iPhone 6S 32GB | £88.99 upfront | Unlimited calls and texts | 8GB data | £31pm
Three has always been good on the bigger data deals rather than the lower byte ones and this one isn't bad. The upfront cost is fairly standard as you can see from the rest of the deals on this page, and the monthly cost the best we could find without paying loads upfront - and there's loads of data here. Total cost over 24 months is £832.99

iPhone 6S 16GB | £84.99 upfront | Unlimited calls and texts | 12GB data | £37pm
Of course Three has always been famous for being the network that still offers an unlimited data option, but we're going for the 12GB option here - it's a lot cheaper and we're willing to bet that most people only want unlimited data for the safety of it. For most, you'll tremendously struggle to get through 12GB. You'll only chew through it if you're downloading the internet every month. Total cost over 24 months is £972.99

iPhone 6S 32GB | £125 £75 upfront | 3GB data | Unlimited calls and texts | £26.50 per month @ Mobiles.co.uk
3GB has become the sweetspot for most users as it allows a decent amount of freedom when away from Wi-Fi hotspots. Sure, you're not going to get much Netflix watched on the bus, but it's plenty for casual browsing, email, Facebook and a few YouTube videos.  By comparison this price is nearly £140 cheaper than the next best 3GB deal at the time of writing!
