United Kingdom

Telefónica starts operating in the United Kingdom in 2006, after acquiring O2, which becomes the commercial brand of Telefónica UK Limited. With 25 million mobile customers, O2 has been independently recognised by Ofcom as the mobile operator with the highest customer service satisfaction - a position it has held for the last seven years. As a result, Telefonica UK maintained market leading contract churn and continued growing its high value customer base.

O2 runs 2G, 3G and 4G networks across the UK, as well as operating O2 Wifi, with over 6 million clients, and owning half of Tesco Mobile. O2 has over 450 retail stores and sponsors The O2, O2 Academy venues and the England rugby team.

Some key statistics in 2018:

  • Telefónica has 32.9 million accesses in UK
  • Telefónica’s revenue in UK reached €6,790 million and OIBDA, €1,865 million.
