The best 3 mobile deals in March 2017

Find the perfect deal on a 3 mobile phone contract

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. 

The network once had prices so low you could get a better deal on this network for pretty much any phone. These days it's more of a mixed bag - it's not always the cheapest but it's often very competitive. And the trump card is that Three mobile is the only network to offer deals with unlimited data allowances.

iPhone 7 deals of the month

The best iPhone 7 deals on 3 mobile:

The new iPhone 7 is set to be another smash hit mobile phone 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, but there's an adapter in the box for your old cans, or there's a pair of lightning cable-friendly headphones in the box too. Memory capacity has been given a boost now, with the smallest models now starting at a much more robust 32GB.

Three was on a mission to offer lower costs for this phone, but that's not happened here. For this deal, you get the iPhone 7 Plus for a fairly high cost upfront and then you pay less monthly for 1GB data and unlimited texts - a decent deal if you want the lower end of the data spectrum on Three. Total cost over 24 months is £1085

iPhone 7 Plus 32GB | £88.99 upfront| Unlimited minutes and texts | 30GB data | £54 per month
This is definitely one the best iPhone 7 Plus deals for near-unlimited data right now, although it's a bit higher this month. There's an impossible  amount of data on offer to help you get the most out of the larger phablet screen, and while the phone will set you back a little bit each month there's a low upfront cost and... that's the end of the data scares. Total cost over 24 months is £1384.99

The best iPhone SE deals on 3 mobile:

The iPhone SE looks and feels exactly the same as the iPhone 5S.

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. Three is now running contracts from £28 per month.

cheap galaxy s7 edge deals

The best Samsung Galaxy S7 Edge deals on 3 mobile:

The Samsung Galaxy S7 Edge is a a good deal different to the S6 Edge we saw last year. It's bigger, it's better and there's a real reason to go for it over the smaller Galaxy S7. At 5.5-inches it's a little larger than the S7 but a tad smaller than the Galaxy Note 5 or the S6 Edge+ - it's the perfect size for those who covet the big screen but don't have the big hands to match, thanks to it being curved nicely into the chassis.

cheap three mobile deals

Samsung Galaxy S7 Edge | £74.99 upfront | Unlimited calls | Unlimited texts | 1GB data | £30pm
This is your entry-level look at Three, with the lowest amount of data and a sub-£100 upfront cost to keep things ticking over. It's not going to suit everyone (although the price has dropped this month by a whole pound over the lifetime of the deal), but if you're wedded to the numerical network, hanker after this phone and don't want to spend a lot, this is your choice. Total cost over 24 months is £794.99

cheap three mobile deals

Samsung Galaxy S7 Edge | Free upfront | 8GB data | Unlimited calls and texts | £35 per month
One of the best Samsung Galaxy S7 deals this month is on Three. Thanks to that curved edge screen, which frankly ruins other phones, the S7 Edge is a phone you'll never tire of. The internal spec shows it's got more than just looks too as it's still a sharp performer. As for this contract, you're looking at a really strong deal as we're used to seeing 5GB deals go for well over £1000 - yet this offers 8GB instead! You can make the lifetime cost cheaper if you pay a little upfront, but we've gone for the 'free phone' version here. Total cost over 24 months is £840

cheap three mobile deals

Samsung Galaxy S7 Edge | Free upfront | Unlimited calls | Unlimited texts | 12GB data | £41pm
This is a decent amount of data per month and for the upfront cost it's not the worst barrier to entry. £41 per month isn't the highest cost in the world (although you can get that down to £36 if you pay a bit upfront), and it'll give you a decent slug of bytes to play with. Do take a look at our deals comparison engine though - as mentioned, there are some good 12GB deals for a higher upfront cost and less per month if that's your poison. Total cost over 24 months is £984

cheap galaxy s7 deals

The best Samsung Galaxy S7 deals on 3 mobile:

The Samsung Galaxy S7 has been around for a few months and is still the cheaper one of the 'best phone in the world' duo, with the S7 Edge a tasty - if more expensive - alternative. As is the techradar way we've found all the best deals from Three and their partner stores online for this high end phone -and the good news is that while we were expecting the Galaxy S7 deals to be very expensive to start with, it's already come down a little in price - the UK market is very competitive, and prices do alter regularly. So if you're thinking about buying one it might be best to go early rather than wait a while – prices could easily go up in a few weeks.
