Let's talk

Our purpose is to make every day better through personal experiences that count. Everything we do is inspired by our company values – bold, open and trusted – along with our business principles, and a clear focus on putting our customers first.


Our customer-led, mobile-first strategy is all about delivering a standout customer experience and helping our customers get the most out of mobile connectivity.


We were awarded Best Network Coverage in 2020 by Uswitch, for the third year running. We run 2G, 3G, 4G and 5G services in the UK, with over 32 million connections to our network. And we operate our O2 Wifi service all across the country.

We’re the network of choice for mobile virtual network operators such as giffgaff, Sky Mobile and Lyca Mobile. We also manage a 50:50 joint venture with Tesco for Tesco Mobile.
