Our networks: At the heart of everything we do

We've been building and operating networks for more than 25 years. In the UK we have over 23 million customers. As part of Telefónica we are the largest integrated fixed and mobile telecoms company in the world, with 300m customers across 25 countries.

Through our own networks and partnerships with other leading operators we can meet all your communication needs. Voice and data. Fixed and mobile. National and international.

Keeping people connected while on the go


Our 3G network provides over 84% of the UK population with voice and high-speed data services. The addition of HSPA+ and HSPA+ dual cell, the latest version of 3G technology, means we will soon be offering even faster 3G speeds for our customers.

And we're the only operator that has committed to a regulatory requirement of reaching 98% of the population with indoor 4G coverage by 2017. Our network investment means we can accelerate our rollout plans and achieve this up to two years early. And we're not going to focus on just one technology and leave others behind. We're doing the same for 2G and 3G. So the majority of people on O2 will get a better experience with voice and data, even if they're not early adopters of 4G.

O2's 4G Network now covers over 17 million people in the UK, across 13 key cities and over over 120 surrounding towns up and down the country. See full network coverage information.

4G means better business outcomes. Increased productivity. An enhanced customer experience. It will allow more agile working, such as uploading and transferring huge files like video on the go.

Investing for the future


We invest £1.5 million a day in our network.

To help speed things up, we have a pioneering partnership with Vodafone to share network infrastructure.

A single solution for your communications


Our fixed network services encompass landlines, digital lines, telemarketing numbers, business broadband and connectivity for your offices and sites. We also provide telephony equipment. And there's a choice of support packages for all our services.

Fast, free, easy wifi. For everyone.


O2 Wifi recently celebrated its six millionth customer.

More than 8000 venues around the UK offer O2 Wifi and the number is growing all the time. Anyone can connect for free – even if they're not O2 customers. There's a one-time registration, and then connection is automatic, with no usernames or passwords.

By the end of 2013, we're aiming to provide wifi to 12,000 venues across the UK.

We've also rolled out the service in some of the busiest parts of London. This means customers can get fast, free, reliable wifi in popular areas like Leicester Square, Piccadilly Circus and Exhibition Road.

O2 Wifi's latest partnership, with Westminster City Council and the Royal Borough of Kensington and Chelsea, ensures that London's one million or so daily visitors and commuters can stay online when they're out and about.

The new scheme in London runs at no cost to the council or the taxpayer and spans Exhibition Road, High Street Kensington, Parliament Square, Trafalgar Square, Oxford Street and Regent Street, Leicester Square and Piccadilly Circus.
