Compare O2 Deals

O2 is one of the most familiar mobile phone network operators in the UK, having launched all the way back in 1985. Pitted up against its nearest rival, Vodafone, O2 found it difficult to compete until 2000, when the industry boomed.

The network has been known under many names, from Cellnet and BTCellnet, followed by the most familiar One2One. However, the condensed O2 was chosen in 2002 before being acquired by Spanish company Telefónica in 2005.

At present, O2 is the second largest UK network, after EE, and covers almost the entire country with 2G, 3G and 4G coverage.

O2 4G

O2 launched its 4G service in December 2013 in order to rival EE, which, at that point, was the only provider of 4G network in the UK.

4G is offers the fastest internet connection on a mobile device yet, with O2 is continuously developing its coverage to more regions across the country. So if you’ve got one of the latest 4G compatible smartphones, make sure you’ve got a super speedy 4G contract to go with it.

Sponsorship

Another great thing about O2 is that it isn’t just any ordinary phone network. In fact, O2 has put its name on some of the biggest music establishments in the UK. In some areas replacing Carling Academies, O2 arenas and academies have popped up through the country, supporting musicians and music fans alike.

In fact, the Millennium Dome in London was renamed the O2 Arena in 2007, providing a venue for some of the world’s biggest artists, from Beyoncé to Justin Timberlake. The Arena was also host to the gymnastics events during the Olympic Games in 2012.

O2 Priority

O2 is also one of the best networks for offering benefits to its customers. Whilst Orange might provide users with Orange Wednesdays- 2 for 1 on mid-week cinema tickets-  O2 offers O2 Priority, giving its customers access to all events at the O2 Arena and O2 Academies 48 hours before the general public.
