Three Mobile Phone Contracts Features

Their Network

With Three, you can stream, play, watch, roam, explore and more on their network.

Whatever you love to do on your phone, they’ve got you covered. The network reaches 99% of the UK population and is great for browsing, calling and texting. As a Three customer, you might also be able to take advantage of 5G, which is great for super-fast streaming, razor-sharp gaming and near-instant downloads.

You can also be sure they’re investing to bring faster speeds and better coverage across their 4G and 5G networks as part of their Big Network Build.

Roaming and International

Three is the ideal network for roaming. With Go Roam, you can use your phone abroad at no extra cost — up to fair usage limits.

Go Roam in Europe and Around the World is now available in a total of 71 destinations on all their Advanced Plans. You can use the Three app to check if your device is ready to be used abroad or log in to My3. Go Roam lets you call, text and use your data allowance, so you can sit back, relax and use your phone without having to worry about roaming charges.

It will start working automatically when you arrive in a Go Roam destination, if you have data roaming switched on. Go Roam is made up of Go Roam in Europe, which is available automatically on all Three plans, and Go Roam Around the World, which is available on all plans except the Essential Plans.

With Go Roam in Europe, you can use your allowance to call and text back to the UK and use your data, as well as make calls and texts between their Go Roam in Europe destinations, and it won’t cost you a penny more. If you don’t have any allowance left, you8’ll also benefit from competitive roaming rates. If you’re travelling to one of their Go Roam Around the World destinations, you can also use your allowances to call and text the UK, and use your data, at no extra cost.

If you want to call and text abroad from the UK, meanwhile, you can do so to 55 countries around the world from £5 a month. Their flexible and recurring add-ons will make it easy to stay connected to friends, family and colleagues — and help you save money at the same time. Your allowance will refresh each month and you can cancel at any time.

5G on Three

Whether you want to effortlessly video call friends and family in different time zones, stream the big game in real time or play video games with your kids, you can live your life in 5G with Three.

Thanks to their super-fast 5G, you’ll find it easier than ever to enjoy the connections which make life better. They have dedicated 140MHz of spectrum to delivering their 5G service, which is 500MHz more than any other UK network operator.

Their coverage checker will show you if you’re in one of their 5G zones. All their SIMs get access to the 5G network at no extra cost, so if you choose one of their phone contracts, you could get ready for quick and smooth 5G on the move.
