The best 3 mobile deals in July 2017

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 - even away from Black Friday.

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 7 and Samsung Galaxy S8. 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 Three's 30GB SIM only deal for just £18 per month.

iPhone 7 deals of the month

The best iPhone 7 deals on 3 mobile:

The new iPhone 7 is yet 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 generous 32GB.

iPhone 7 32GB | £74.99 upfront | Unlimited calls and texts | 30GB data | £33 per month
This is our favourite big data deal on the iPhone 7. The price of the handset is more expensive than last month, but now it's down to just £33 per month for 30GB data and unlimited everything else! Extremely strong if you need a lot of data or if you don't "need" the data but would like a safety net. And bear in mind that going unlimited is way more expensive. Total cost over 24 months is £866.99

iphone 7 deals

iPhone 7 32GB | £124.99 upfront | Unlimited data, calls and texts | £48 per month
If you want to get an iPhone 7 with unlimited everything 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. That being said, with 30GB available for just £36 per month, the above deal is the one we'd go for! Total cost over 24 months is £1276

iphone 7 Plus deals

iPhone 7 Plus 32GB | £100 upfront | Unlimited calls and texts | 8GB data | £37 per month
Three will give you a tasty amount of bytes for streaming video on the larger phablet screen, and while the phone will set you back a fairly large amount after that it's a reasonable rate per month for a lot of data and unlimited everything else. A few quid more a month will get a better deal below, however. Total cost over 24 months is £988

This is definitely one the best iPhone 7 Plus deals for near-unlimited data right now, and it just got even better thanks to the price of the handset being reduced to a big fat ZERO! There's acres of data on offer to help you get the most out of the larger phablet screen and put and end to the data scares. Total cost over 24 months is £1008

cheap three mobile deals

Samsung Galaxy S8 | £9.99 upfront | 8GB data | Unlimited minutes and texts | £36pm
This deal from Three is one of the best around. It's the cheapest Samsung Galaxy S8 deal on Three (£2pm cheaper than last month).

Samsung Galaxy S8 | £74.99 upfront | 30GB data | Unlimited minutes and texts | £36pm
30GB tariffs for the Galaxy S8 have gone downhill this month - they're no longer anywhere near as impressive as they were. But this deal shades it at the moment. The upfront fee is reasonable enough, but it's that £36 monthly fee that marks this out from the rest when you consider just how much data you get. Total cost over 24 months is £938.99

Best Samsung Galaxy S8 Plus deals on 3 mobile:

cheap three mobile deals

Samsung Galaxy S8 Plus | £19.99 upfront | 8GB data | Unlimited calls and texts | £43pm
If you don't need huge amounts of data, this 8GB deal is competitive. We'd be tempted to go for the larger 16GB Vodafone deal mentioned earlier - it's cheaper than this. Three becomes a lot more attractive if you start cranking up the data; just look below to see what we mean. Total cost over 24 months is £1057.99.

Samsung Galaxy S8 Plus | £19.99 upfront | 30GB data | Unlimited calls and texts | £45pm
Three is offering the cheapest 30GB deal of any network so far and this deal is almost £4000 cheaper than the most affordable unlimited data deal over the 24 month contract. 30GB is a serious amount of data a month and the savings speak for themselves. So don't go for unlimited for the sake of it... Total cost over 24 months is £1099.99

Samsung Galaxy S8 Plus | £99 upfront | 600 mins | Unlimited calls and texts | £58.15pm
There's no getting around it. The cost for true unlimited data access per month is incredibly high. Three still won't give you the handset for free upfront either! We've chosen this deal with a 600 minute call restriction as it's over £100 cheaper than unlimited and you can always use apps like WhatsApp to make calls with all that data instead. But bear in mind that going for 30GB instead is considerably cheaper (see above). Total cost over 24 months is £1494.60

cheap iphone se deals

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 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 | £9.99 upfront | Unlimited minutes | Unlimited texts | 30GB data | £30pm
Three has long been the network synonymous with big data, and it's no different on iPhone SE deals. 30GB is absolutely stacks of data - you'll have to try quite hard to use more than that every month. The handset is now a tenner instead of free like last month, but the monthlies are an easy to compute £30 a month. The total cost of this deal over 24 months is £729.99

Now succeeded by a newer model, Samsung's Galaxy S7 is still a superb phone. And now it's a generation older, there's an even better chance of getting it at a bargain basement price.

Samsung Galaxy S7 | £25.99 upfront | Unlimited mins and texts | 4GB data | £25 per month
This time last month, we were pushing this deal hard. It's a fantastic price and wasn't much more than the one above. Now that you have to pay £30 at the outset, it's not so cut and dried. days. Trust us though, this is still a cracking deal on the Galaxy S7. Total cost over 24 months is £625.99

Samsung Galaxy S7 | £19.99 upfront | 30GB data | Unlimited minutes  and unlimited texts | £29 per month
Three's smashing it up with high-data deals, so if you want the next best thing to unlimited, you might as well jump straight to 30GB. Considering it's not much more than £100 dearer than the last couple of deals over the two years, we'd be very tempted to go for this one. Total cost over 24 months is £715.99
