The best Three mobile deals in September 2019

Three mobile deals

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.

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 XR and Samsung Galaxy S10.

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 the 100GB Three SIM only deal for £20 per month

Huawei P30 Pro | £79 upfront | Unlimited data | Unlimited minutes and texts | £51pm
If you're a big data user then we can only assume the idea of unlimited data has tempted you a few times. If so, this could be the deal for you. Three, the master of unlimited data, is offering up the idea of no data caps for just £51 a month and £79 upfront - sounds great right? This doesn't even push the cost of the device much higher than other P30 Pro contracts. Total cost over 24 months is £1,303

Huawei P30 Pro | £29 upfront | 100GB data | Unlimited minutes and texts | £38pm
While going for the unlimited data offer feels incredibly tempting, dropping down to 100GB could be the better way to go. It's much cheaper and isn't really that much data. If you're not fussed about having a data cap, we would advise going with this option instead. Total cost over 24 months is £941

Three mobile deals on the Samsung Galaxy S10

Samsung's newest release, this phone is rocking a completely flat, notch-less screen with a pin hole camera, giving it a unique style. Whether it's the triple cameras on the back, fast processor or reverse charging, there is a lot to love here.

Samsung Galaxy S10 | £79 upfront | All-you-can-eat data | Unlimited minutes and texts | £54pm
We know, we know. Sometimes only unlimited data will do. Well you're going to have to go for Three then, aren't you. The monthly payments for unlimited Netflix binging, heavy Facebook scrolling and Spotify streaming through the night away from Wi-Fi are on the high side, but at least there's not too much to spend upfront. Total cost over 24 months is £1,375

Samsung Galaxy S10 | £49 upfront | 100GB data | Unlimited minutes and texts | £38pm
Normally we would recommend one of Three's unlimited plans if you were going for big data, but this 100GB offer feels impossible to say no to. Costing £34 a month with not a huge amount upfront, this comes in at an average S10 price while offering you a tonne of data. Total cost over 24 months is £961

Three mobile deals on the Samsung Galaxy S10e

Samsung's brand new budget flagship, the S10e features high-end specs for an affordable price. If you want the best Samsung has but don't want to have to pay through the roof to get it, this is the way to go. With all of the same features as the S10 with a few cutbacks, this is a high-end phone with mid-range pricing.

Samsung Galaxy S10e | £49 upfront | 100GB data | Unlimited minutes and texts | £31pm
When this deal first came out, it had monthly bills of £25. Granted that was slightly ridiculous so when they pushed the prices back up, we had no real complaints. Now at £31 a month and £49 upfront this is still an exceptional offer and arguably the best of the Samsung Galaxy S10e deals currently available. Total cost over 24 months is £793

Three mobile deals on the iPhone XR

The iPhone XR hits a sweet spot between high tech and reasonable pricing. It looks a lot like its more powerful brethren - both in appearance and on the spec sheet - and boasts a glorious 6.1-inch Liquid Retina display and A12 Bionic chipset without a £1,000 price tag.

iPhone XR | £49 upfront | All-you-can-eat data | Unlimited minutes and texts | £52pm
Right now, unlimited data on the iPhone XR has never looked better. For the first six months of your contract, you pay just £29 a month. That is a ridiculous price for this contract and although it sadly goes back up to its regular pricing of £52 after the six months, it will help you save a bit of cash. Total cost over 24 months is £1,110

iPhone XR | £49 upfront | 4GB | Unlimited minutes and texts | £45pm
Where there is absolutely no doubt around Three's prowess over the unlimited data scene, it seems like they struggle a bit more when it comes to the cheaper end of the spectrum. If you're looking to get a Three contract at its lowest price it will cost you around £45 a month. But, you will be capped at 4GB of data, we would advise just sticking to Three for unlimited data options. Total cost over 24 months is £1,129

Three mobile deals on the Samsung Galaxy S9

OK, so the Samsung Galaxy S9 doesn't make massive strides on the S8, but that doesn't mean it's not still one of the premier Android phones on the market. The cameras in particular are awe inspiring and tangible improvements have been made to the biometrics and position of the fingerprint scanner.

Samsung Galaxy S9 | £49 upfront | All-you-can-eat data | Unlimited minutes and texts | £42pm
Three may not have the pricing fire power of the other networks, but it does have a handy trick up its sleeve to persuade you to grab your new S9 contract with the numerical network. This tariff gives you absolutely unlimited data - the kind of volume other networks just can't reach.Total cost over 24 months is £1,057

Three mobile deals on the iPhone XS and iPhone X

Three mobile deals

Oh gosh, Apple went and did it. After years upon years of incremental upgrades, it finally made something special to celebrate the 10th anniversary of the iPhone. For the iPhone X it has dropped the bezel altogether, while the 5.8-inch Super Retina HD is scarily good - and then it tweaked things a year later for the XS. Marvellous!

iPhone XS | £49 upfront | 100GB of data | Unlimited minutes and texts | £52pm
You know how the expression goes 'big data phone contracts cost the world but they make your life so much better'. Okay, so no one has ever said that but it is true. You do have to fork up a big ol' £52 a month and £49 upfront, but once you do you'll have 100GB of data on one of the best phones in the world, sounds fun right? We'd say so. This is our go to iPhone XS deal right now.  Total cost over 24 months is £1,297

For the first six months of your contract you'll be paying £30.50, then for the rest of your contract you'll be paying £61 a month. The first six months should help make your contract more affordable. Total cost over 24 months is £1,281

Three mobile deals on the Samsung Galaxy Note 8 and Note 9

Samsung has now well and truly put the flaming memory of the Note 7 behind it. If the Note 8 was exceptional (6.3-inch infinity display and 6GB RAM), then the Samsung Galaxy Note 9 is even bigger and better (6.4-inch infinity display and 8GB RAM). If you want the best big screen Android phones on the market, then look no further.

Samsung Galaxy Note 9 | £49 upfront | All-you-can-eat data | Unlimited minutes and texts | £44pm

Three mobile deals on the iPhone 8

Thanks to the spectacle that was the iPhone X launch, the reception for the iPhone 8 was a little bit flat. Perhaps unfairly - it improves on the iPhone 7 with wireless charging and an improved camera. Plus, it's quite a bit cheaper. So if you're looking for the best iPhone but balk at the iPhone X expense, try the 8 on for size instead.

iPhone 8 64GB | 49 upfront | All-you-can-eat data | Unlimited calls and texts | £51pm
Currently, Three is offering a bit of a discount on its unlimited data contracts. That means for the first six months, you only have to pay £25.50 for this contract. After that, your bills will jump back up to £51 a month. Total cost over 24 months is £1,071

FAQ on Three mobile deals

What are the benefits of Three?

The benefits of getting a Three mobile deal can be split into three main categories:  

Another factor that has made Three so popular is its offer off massive amounts of data (or even unlimited) at some brilliant price points. 

Can I keep my number when I switch to Three?

You sure can, if you switch over to an Three mobile deal and want to keep your old number, then simply call your old network, get a PAC code and transition it over. 

If you were previously on Three, you can still keep your number but it is slightly more complicated. They won't let you keep your number, so you have to use this workaround. Buy a free pay-as-you-go SIM from any other network and tell your network that you're moving. 

They'll release the PAC code, which you then give to the substitute network. Then, you immediately get another PAC code from them. Take that to your old network, and they'll move your number to your new contract. Long winded, but easier than learning a new number!

Can I use my Three phone abroad?

When it comes to roaming abroad Three mobile deals are a pretty great way to go. With access to free roaming anywhere in Europe and options in at least 71 countries, Three trumps the rest for roaming charges.

There are select countries where you will have to pay extra to use your data, you can check Three's website to find these countries.
