Terms and conditions

With Personal Hotspot, you can use your phone’s data allowance to connect up your other devices. Pretty handy for when you’re nowhere near a Wi-Fi connection. On our Essential Plans, you can’t use your inclusive data allowance to create a personal hotspot.

With our Advanced plans, you can unlock your UK allowances for 24 hours in Go Roam destinations. It’s £2 in Go Roam in Europe, and £5 in Go Roam Around the World destinations. Republic of Ireland and Isle of Man are excluded from the daily roaming charge. Our Fair Use Policies apply.

With Personal Hotspot, you can use your existing data allowance to connect other devices to your phone and get online. Pretty handy when there's no Wi-Fi.

The 5G revolution is upon us. And from launch, all new and existing customers with a 5G Ready device can join the party. Whether you are on a contract, SIM only or PAYG.

Got a 5G Ready handset now? Sweet. All our SIMs are 5G ready at no extra cost. Obvs. And as soon as 5G comes round your way, you’ll be able to frolic in 5G wonder.

You’ll be able to upgrade your data plan whenever you need. To enjoy 5G at full pelt, with uncapped speeds, choose an Unlimited data plan - so you never run out of data juice.

With a business plan on Three, you get up to £500 worth of benefits from our partners to support your business. From creating stationery with Moo, to nailing the accounts with a 6-month FreshBooks subscription - we’ve got you covered, whatever your business needs.

Our Business plans let you use Go Roam Around the World in 71 destinations, at no extra cost. You can also use your phone as a Personal Hotspot, and call free from your mobile to Customer Services.

Use our Advanced plans in 71 destinations around the world, for a low daily charge of £2 for Go Roam in Europe and £5 for Go Roam Around the World.

With our Essential plans you’ll save some money on your contract but miss out on features such as Go Roam Around the World and Personal Hotspot allowance, although you’ll still be able to use Go Roam in Europe. For limits and further information - see Three.co.uk/go-roam.
