UK network O2 is set to launch a 4G service on August 29th to compete with EE who is the only network currently in the UK offering the technology. The 4G rollout will come to three markets at first; London, Leeds and Bradford, then ten more cities by the end of the year. Unfortunately it seems what O2 is offering won't be close to as good as EE. For a start it will be more expensive, initially slower, and won't work with the iPhone 5's LTE bands. Telefonica UK CEO Ronan Dunne said he "would be frankly gobsmacked if [Apple's] roadmap didn't address that issue."
O2 expects to reach 98 percent of the UK by the end of 2015. UK networks Vodafone and Three are also expected to launch 4G networks but it's still unknown when this will happen.
