Why choose Three?

Three is one of the UK's biggest mobile phone networks and is a popular choice for millions of smartphone users, thanks chiefly to its affordable tariffs. 

It regularly has some of the cheapest and best SIM only deals on the market and when compared to other major networks, offers plenty of bang for your buck in terms of calls, minutes and rewards. It's also one of the few networks to give unlimited data on its SIM only tariffs. 

While it doesn't offer as much coverage on its 5G network compared to others, it is working to improve this and promises a fast rollout. However, its 4G coverage is excellent and has 99% UK coverage.

What other plans are available with Three?

With Three you can find some great deals which include the latest smartphones from the likes of Apple, Samsung and Google. However, its worth noting that its device range isn't as extensive as other networks, but you do get more opportunities to upgrade to unlimited data tariffs without lumping on sizeable additional costs.

What really sets Three apart is its range of affordable SIM only plans - the majority of which come with unlimited calls and texts.

These plans can start from as little as £8 a month, through to top-end options with unlimited data for around £28 a month. Often Three will also give introductory offers and incentives for you to take on its longer 24-month plans, including half price monthly payments for the first six months.
