O2 History

O2 have a long and impressive track record in the UK, reaching all the way back to the beginning of mobile telecommunications technology in the middle of the 1980s. First established as Cellnet in 1985, the network initially had close ties to BT, which eventually would become sole owner of Cellnet in 1999.

O2 spun off from BT in 2002 and was acquired by the Spanish telecoms giant Telefónica for more than £17 billion in 2005. Telefónica have overseen O2's growth into the country's second largest mobile network provider, going from approximately 5 million customers to more than 34 million and successively rolling out 3G, 4G, 4G+ and 5G technology for their customers.

Much has changed since the early days of mobile communication when a single phone call would cost you a quid and the only devices available were the Motorola brick (although, credit where credit's due, if you think "Hey Google" is a cool new marketing gimmick take a look at Motorola's "Hello Moto" campaign more than 2 decades ago). These days, you can choose from a whole catalogue of devices and monthly plans that focus on data usage rather than calls.

Through all those changes, though, you can still be sure that your mobile service is of the highest quality achievable. Take a look at the O2 deals we have highlighted on this page for you and earn unbeatable savings when you next get your new plan.
