Life’s better without limits. That’s why we offer truly unlimited data in the UK. Unlike other networks, three won’t cap your speeds, and there’s no fair usage policy. So, you can get stuck into 5G on the UK’s Fastest 5G Network with a phone, tablet, broadband or SIM plan on Three.

For watching the game without buffering. Super-smooth video calling around the world. And near-instant downloads. Plus, all our SIMs are 5G Ready at no extra cost.

Is there any limit on Unlimited Data?

Our unlimited data plans are the best, because the data is truly unlimited and you never need to worry about your next bill. There are no speed caps, no data caps, and no hidden limits when you’re using our unlimited data in the UK.

Can i use unlimited data abroad?

With Go Roam you can use your unlimited data in over 70 destinations around the world, at no extra cost. The usage policy can vary slightly, so make sure you check out our Go Roam information before you travel.

Can i use my data to tether to other devices?

Yes, if you’ve got unlimited data included in your plan you can use your phone as a personal hotspot. It’s called ‘tethering’ and it means you can connect other devices to your phone and use the phone plan data to get online. It’s perfect on long car journeys, if other people in the car need to get online on iPads or other devices. Or whenever you’re away and can’t find a Wi-Fi hotspot for another device.

Does unlimited data mean unlimited personal hotspot?

Yes. You can use your unlimited data allowance as a personal hotspot and connect other devices when you don’t have access to Wi-Fi.
