About Three Mobile
At Three we believe the mobile industry sucks, and for too long it's gone unchallenged. We’re changing all that. From being charged expensive roaming fees, to having to pay extra for 4G, we're taking a stand to #makeitright.
Our aim is to make life easier for our customers by helping them get the most out of their mobile devices, offering real value from the services we provide and by removing the barriers that frustrate them.
We’ve doubled the size of our network over the past 8 years, and now cover 98% of the UK population. We also carry over 40% of the UK’s mobile data. Our hard work has paid off and we’ve recently been rated the best network for the internet on smartphones.
On top of all this, we're now the UK's least complained about network.
Here’s just a few of the ways we’re making mobile better…
Feel At Home – in 42 destinations.
With Feel At Home on Three you can use your phone abroad at no extra cost in 42 destinations. That's more destinations than any other UK mobile network.
We want to take the panic out roaming so you can enjoy the stuff that matters, like posting live tanning updates from your lilo.
First to offer all-you-can-eat data.
With all-you-can-eat data you can use as much data as you want. Download apps, browse the web, look at maps and check your emails as often as you like without worrying about going over a data allowance.
First to make 0800 calls free.
We don’t think you should have to pay to make calls to 0800 numbers. That's why we were the first network to make all 0800 calls free on our new contract handset plans.
Your Three phone, unlocked.
Regardless of the make or model, and the price plan you choose we sell all of our phones unlocked.
With Three inTouch Wi-Fi Calling, you can call and text whenever you're on Wi-Fi in the UK, even if there’s no mobile signal.
Pay As You Go lowest rates and no expiry.
We believe Pay As You Go should be flexible and simple to use. So we’ve got the lowest Pay As You Go rates and top-ups that never expire. That's 3p a minute, 2p a text and 1p per MB of data.
Great customer service.
We know how important good customer service is. That's why we recognise our staff for good customer service as well as sales.
No nasty bill surprises.
Nobody likes nasty surprises on their bill. That's why we're here for you to explain what you need to know about our prices and any changes to your bill.
No extra charge for 4G.
We believe you should get fast internet without having to pay extra. So 4G is included for free for all our customers.
With Three Rescue™ you can get a replacement phone the very next day. We know how important it is not to miss the WhatsApp message about impromptu drinks after work or that important birthday reminder on Facebook.
