Our networks

We were the first UK operator to switch on a fast 3G network and Ofcom reports that O2 has the fastest 3G data coverage in the UK. Our 3G network provides over 84% of the UK population with voice and high-speed data services of up to 14.4Mbps. This will soon be 21Mbps, meaning downloads will be 30% faster.

We were also the first UK operator to run a 4G/LTE trial network. It has demonstrated peak speeds of over 100Mbps to a mobile device.

Independent testing by Metrico and Siroda shows we offer the best overall data experience in the UK. Ofcom rates us as the fastest mobile broadband provider overall.

Investing for the future

Over the last few years we've spent over £1 billion building and improving our network. This year we'll invest another £500 million.

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

O2 Wifi. Fast, free wifi that anyone can use

By the end of the year we'll have set up thousands of hotspots. And by 2013, we'll have 14,000 hotspots across the UK - double the number any of our competitors offer now.
