O2’s new 4G network is being switched on tomorrow (Friday) in a further five cities. Birmingham, Coventry, Leicester, Nottingham and Sheffield are going live.
The network was launched in August in London, Leeds and Bradford, with Vodafone also turning on its 4G network in London that month too. EE - which includes the T-Mobile and Orange brands - launched its 4G network last year, and it now covers over 60 percent of the population.
Three has yet to confirm its 4G launch date, but it is expected to make the move before the end of the year.
O2 says the eight cities it now offers 4G coverage in means 9.5 million people can be reached. O2 says five more cities will be added to its 4G coverage "by the end of the year".
O2 says it is investing £1.5 million a day in all its networks, promising better coverage for existing 2G and 3G customers too.
A range of O2 4G tariffs are available, starting at £26 a month and all including unlimited minutes and texts.
Ronan Dunne, CEO of Telefónica UK (O2) said: "The full potential of 4G is as yet unexplored. But over half of our customers say they use more data than two years ago, as can be seen by the 79 percent increase in Coventry alone over the last 12 months. Given this trend, there is no doubt that 4G will transform our lives."
