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 .

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.
Three’s PAYG has lots of benefits:
Tips for getting the best mobile phone deal on Three

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