Shopping on Three

Three is first and foremost a mobile telecommunications enterprise and as such it has the best deals on mobile phones in the industry. Three makes available to its customers a wide array of offers which goes from just SIM cards to the most sophisticated mobile phones in the market, which can come with flexible pay-as-you-go or pay monthly plans. Not only that, but Three also makes it possible for pay-monthly customers to bring their old mobile phone and exchange it for a new one at a set price. All plans at Three come with unlimited minutes and texts, and with the advantages of the Go Roam promotion, a great Three deal that allows customers to call and text the UK and use data out of their UK allowance when abroad.

As well as mobile phones, though, Three has superb home and mobile broadband offers. Three's wireless broadband uses its own signal network, so no landline connection is required. This means cheaper Internet and shorter waiting time, with no fixed landline rental fees and no need for an engineer to come and setup your connection. 4G broadband with Three is already available in 99% of the country and can be accessed for as little as £21 per month. An all-new 5G Three offer is being phased in in London first but will soon be available nationwide. With 5G technology Three is ushering in the future of Internet connections, with load times, buffering and the infuriating spinning cursor wheel a thing of the past.

What does Three offer?

So you've been wanting a new phone for some time but you don't know if you can afford it. Well, this is your chance! Browse our page for the best Three promo codes and head to the website to get your spanking new phone. Choose from a selection of several dozen and even get some money back for your old clunker when you trade it in. Pay monthly contracts start at a reasonable £20 and less, while downpayment for the device is often not more than £20 or £30.

If a phone is just too small-world for you, why not get a tablet with your phone line. The selection from which to choose is more limited than mobile phones but you still get approximately ten tablets as alternatives, most of them with no upfront payment. Or maybe you've been looking for the right set of portable sound kit to enhance your music on the go. You can also get all sorts of accessories from Three's online shop, including bluetooth speakers, wireless headphones, protective cases and wireless charges, to name but a few.

Maybe your connectivity needs require you to get mobile broadband. Carry your Internet connection in your pocket with the 4G mobile WiFi with unlimited date from just £22/month, or else get a data only SIM for your tablet. With the expansive Go Binge deal you get unlimited streaming on selected apps and you can use your data with no restrictions in more than 70 countries.

About Three

Three is the British subsidiary of a Hong Kong-based telecommunications company with a presence in several countries in Europe and Asia. In the UK, Three offers mobile connection and broadband Internet to its customers through the fastest-growing network in the country. Three's infrastructure has been conceived with data traffic, rather than telephone calls, in mind, which is why connection speeds are so quick. And that is even before factoring in Three's 5G network, which is currently under construction and will be the UK's fastest ever!

If you're looking for a phone or you're after a better home broadband service than your current provider, then take a look at these Three deals – you might be surprised by what you find. With Three you get unlimited data on dozens of mobile phone plans, both pay-as-you-go and pay monthly. Or, if you already have a device, you can get a SIM only, with the most competitive plans in the industry. There's literally no reason not to switch to Three: you even get to keep your old number while at the same time joining the most advanced Internet service provider. This, in an eminently digital era, is simply elementary.

Three history

The story of Three in the UK begins, fittingly, in 2003. Not just any day of 2003 but the third day of March. 03/03/03 – get it? In fact, the number three was such a thing for Three that there was a three to trump the three threes from the launching date: at the time, wireless mobile telecommunications was being revolutionised by the deployment of third generation technology, commonly referred to as 3G. That's right , Three launched in the UK on 3/3/3 primarily with a 3G platform (at a time when 2G was the rule).

Since the days of the magic number Three has grown significantly, moving away from 3G to develop 4G and 5G technology. The fastest growing network in the UK, Three's 4G signal reaches 99% of the country and processes approximately 40% of the traffic. Three has always abided by the company mantra of openness, being the first UK provider to offer unlimited data and keeping a fully tolerant approach towards Internet applications such as Skype, which in the face of it would appear to threaten its business model.

But Three is not here to police the telecommunications industry, it's here to provide the best service to the largest number of customer possible, an ambition that is about to be enhanced with the arrival of the 5G network.
