O2 is a mobile network operator and the principal commercial brand of Telefónica UK Limited, which is part of the global telecommunications group Telefónica S.A, headquartered in Spain and operating in Europe, and North, Central and South America.
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.
We have around 6700 employees and over 450 retail stores. We sponsor England Rugby, The O2 and 19 O2 Academy music venues across the UK.
Our sustainability approach centres around doing the right thing for our customers, people and society. As a responsible organisation, we continue to help to reduce our (and our customers’) impact on the environment, as we increase our positive social impact.
We also create work experience opportunities for 16-24 year olds through our GoThinkBig platform. O2 Recycle lets customers reduce their impact on the environment by recycling their old devices. And our partnership with the NSPCC helps parents to keep their children safe online.
