Key Points

What is Three? 

Three is one of the 'big four' mobile networks in the UK, alongside EE, O2 and Vodafone. 

Three Mobile started out in Hong Kong and launched in the UK on 3 March 2003 (because it loves the number three). Three’s network was built for the internet and was one of the first to offer all-you-can-eat data. 

Today, Three has the widest 5G spectrum of services available and is the only operator to meet IMT 2020 standard for 5G services [1].

Three mobile pay as you go phones 

Pay as you go (PAYG) mobile phones are ideal if you don’t use your phone much or if you’re on a budget. They’re also a great contract-free alternative for parents who want to buy their child a mobile phone without paying a fixed monthly bill. 

However, if you’re a heavy data user, you’d likely be better off with a SIM-only or contract deal. 

We compare phone contracts and SIM-only deals above, however you can find Three PAYG deals on the Three mobile website.

Tips for getting the best mobile phone deal on Three

  1. Compare prices with us to find the right deal for you

  3. Check if it’s cheaper to buy the handset outright and go SIM-only
  4. If you don’t use your phone a lot then have a look at pay as you go options Pay as you go
  5. Benefits, gifts and extras might sound great, but they’ll make your plan more expensive
