Three mobile now offers massive 100GB data tariffs, including £25 SIM only deal

When it comes to offering big data, Three mobile has stood head and shoulders above the competition for some time. Not only does it invariably lead the way over the other major networks for tariffs of 30GB and above, but it's also the only one that stretches to all-you-can-eat data plans.

But if you're in that (admittedly small) venn diagram of requiring more than 30GB of data per month but not wanting to splash out on unlimited, Three's new 100GB tariffs should hit the sweet spot. That's enough data for around 100 hours of Netflix away from the Wi-Fi, or roughly 2,500 hours of Spotify at normal quality.

Below, we'll tell you how much it costs to get the key flagship phones from Three on contract - it's only been rolled out to the most high profile handsets for now. And if you're happy with your current phone, and just want to grab a 100GB SIM card, we'll tell you about the price for SIM only, too.

100GB iPhone 7 deal at Three

iPhone 7 32GB | £79 upfront | Unlimited calls and texts | 100GB data | Advanced plan | £50pm
Apple's flagship phone (for the next month or so at least), the iPhone 7 is certainly the tech giant's best on the market. The big controversy on launch was the removal of the headphone jack, but we're more excited about the water resistant finish and doubling of onboard storage.

100GB Samsung Galaxy S8 deal at Three

Samsung Galaxy S8 | £79 upfront | Unlimited calls and texts | 100GB data | Advanced plan | £53pm
There's a reason why the Galaxy S8 costs the big bucks. It's because it's possibly the best Android phone ever made. We were sold from the second we saw the dazzling 5.8-inch 1440x2560 resolution display, and the incredible power and camera did nothing to dissuade us from this phone's greatness.

100GB Samsung Galaxy Note 8 deal for pre-order at Three

Samsung Galaxy Note 8 | £79 upfront | Unlimited calls and texts | 100GB data | Advanced plan | £64pm
The new kid on the block. Yesterday's launch of the Galaxy Note 8 pulled off a remarkable trick - by making a world full of tech journalists almost instantaneously forget about the disaster that was the Note 7. It's that MASSIVE 6.3-inch Quad HD+ that's so distracting, but this looks like one of the market's leading phones.

100GB SIM only deal at Three

SIM Only | FREE upfront | Unlimited calls and texts | 100GB data | Advanced plan | £25 per month
We frequently find ourselves recommending Three for people wanting a new SIM card - just take a look at our best SIM only deals page for proof of that!

£25 for a huge 100GB of data is a very fine price, but it's far from our favourite big data SIM on Three. Buymobiles is still selling an unlimited data SIM for a mere £22 per month, plus £35 cashback. While we have a real soft spot for Three's £18 for 30GB tariff, if that's enough data for you.

Three Advanced plans

Three has two types of plan that you can choose from. Its Essential plans are cheaper, but all of its 100GB tariffs are Advanced plans.

As well as giving you a personal hotspot allowance and free calls to customer services, there are two main benefits to going Advanced. Firstly, there's Go Roam, which lets you feel at home when abroad by letting you use your data, call and text allowances in 60 worldwide destinations such as the US, Australia and Brazil. And then there's Go Binge allowing you to stream Netflix, TVPlayer, Deezer and SoundCloud away from Wi-Fi without eating into your data allowance.
