Join the network you can trust

We’re here for you whenever you need us.

Why choose the O2 network?

Because more people rely on our network than any other. Every single day we have over 36.1 million connections* pinging on our network, helping people and businesses all over the UK to stay connected to the things that matter.

Here’s why our customers are so loyal


Let us introduce you to Bubl

You’ve probably already seen our robot all over town. Think of Bubl as your little blue buddy. Smart. Reliable. Everywhere. Just like the O2 Network.

Our award-winning network keeps getting better

We’re investing more than ever before to continue making our network service even more reliable for our customers. Since the start of 2020, we’ve added extra 4G capacity into over 265,000 postcodes, as well as rolling out 5G to over 215 towns and cities*.

We’re passionate about rural connectivity and bringing 4G to parts of the UK for the first time.

And we’re committed to becoming a Net Zero network by 2025.

*as of September 2021.

And when it comes to 5G, we’re now live in over 150 towns and cities, with many more rollouts planned this year and beyond. Find out more about 5G.

We’re taking the carbon out of O2

When it comes to sustainability, we want to lead the way. That’s why we’ve set an ambitious commitment to be the first UK mobile network to reach net zero. Across every office, every store and every mast, our goal is to remove non-renewable energy from our network and operation, to be a Net Zero Business by 2025. Find out more.
