When it comes to Apple, there is a clear divide between its top of the line flagship devices with their massive price tags, and Apple's earlier, far more affordable devices with their mid-range specs - the iPhone 6S falls into the latter category.
We've had a fair few new iPhones since the 6S, we've had the 8's, iPhone X's and now the iPhone XS Max (bit of a mouthful really). The good news here is that these new releases have driven the prices of the iPhone 6S way, way down. Sub-£20 a month tariffs appear quite frequently now, so getting a great deal on Apple's 2015 flagship phone makes it a great budget option if you don't want to spend the earth on your new iPhone deal.
If you want more than the minimum of data, then check out our comparison chart below, or head straight down to our pick of the best tariffs on the web.
The 6S may be one of iPhone's older phones now, but it still features a lot of the features we have come to expect from flagships. It has improved battery life and 3D touch, where you can press a bit harder on the screen to get a different response.

The top 5 best iPhone 6S deals in the UK this month:
We've gone all Top of the Pops to show you our favourite five iPhone 6S deals on the market right now - we'll give you a clue...they're much cheaper than the iPhone XS! Read about all of the best iPhone 6S deals here, including tariffs on EE, O2 and Vodafone.
iPhone 6S 32GB | O2 | £10 upfront | Unlimited calls and texts | 1GB data | £18pm
There was a time not too long ago where O2 could not compete on the iPhone 6S, now it has one of the cheapest deals out there. If you use our code 10OFF, you won't have to pay anything upfront and then your monthly costs are just £18 - smartphones don't come much cheaper than that. Total cost over 24 months is £432
iPhone 6S 32GB | Vodafone | 0.99 upfront | Unlimited calls and texts | 2GB data | £22pm
Looking for a Vodafone contract? This is our pick for the best choice right now. Voda prices shot up recently but you can still get this one for £22 a month. On top of that you just have to pay 99p (bank breaking right?) The data may not be brilliant but the price really is. Total cost over 24 months is £528.99
iPhone 6S 32GB | EE | £19.99 upfront | Unlimited calls and texts | 4GB data | £22pm
This deal is fantastic - there is barely anything to pay upfront and £22 per month is pretty reasonable for a 4GB contract. That is more than enough data for your daily streaming and internet usage. And it only gets better still when you factor in the fact you're on the UK's fastest 4G network. Total cost over 24 months is £547.99
iPhone 6S 128GB | EE | FREE upfront | Unlimited calls and texts | 20GB data | £31pm | £45 automatic cashback
If you're more interested in keeping all your songs, videos and photos on your memory card than you are the cloud and streaming, then this is one of the better tariffs currently out there for the 128GB handset. And you don't even have to compromise on the data you use, as 20GB is still a massive amount to play with. This is the best of both worlds when it comes to data and storage and won't really break the bank. Total cost over 24 months is £699 (after cashback)
iPhone 6S 32GB | Three | FREE upfront | Unlimited calls and texts | Unlimited data | £38pm
Been going over your data limit a lot recently? Maybe an unlimited data cap is what you need in your life. If so, this deal could be for you. For £38 a month and nothing upfront you're getting the opportunity to use the internet, stream and scroll through Facebook as much as you want in a month. Total cost over 24 months is £912
It may be very similar to its predecessor, but there's no denying that the iPhone 6s makes a fantastic alternative to the more expensive Apple devices like the iPhone 8 and iPhone XR. The phone works fluidly at nearly every task and will cost you a lot less than Apple's current flagships. Low end cost with high end features
