O2 History

O2 has a rich and notable history in the UK, dating back to the inception of mobile telecommunications technology in the mid-1980s. Initially launched as Cellnet in 1985, the network had close connections with BT, which ultimately became the sole owner of Cellnet in 1999.

O2 separated from BT in 2002 and was purchased by the Spanish telecommunications conglomerate Telefónica for over £17 billion in 2005. Telefónica has guided O2's expansion into the second-largest mobile network provider in the country, increasing its customer base from around 5 million to over 34 million, while successively rolling out 3G, 4G, 4G+, and 5G technologies for its users.

Much has evolved since the early days of mobile communication when a single phone call would cost a pound, and the only available devices were the Motorola brick (though, to give credit, if you think "Hey Google" is an innovative marketing strategy, take a look at the "Hello Moto" campaign from Motorola over two decades ago). Nowadays, you can select from a comprehensive array of devices and monthly plans that prioritize data usage over calls.

Through all these transformations, you can still trust that your mobile service is of the finest quality possible. Check out the O2 deals we have showcased on this page and receive exceptional savings when you get your new plan.
