EE customers in central London will today be able to surf the web at speeds of up to 150Mbps, after the carrier turned on its next-gen CAT6 network technology.
The super-fast, so-called '4G+' service will be available in Shoreditch, Old Street, Southbank, Soho, Westminster and Kensington, with plans to extend it across Greater London by June 2015.
After that, next in line are Birmingham, Liverpool and Manchester, as EE bids to once again press home its 4G first-mover advantage.
To enjoy the faster service, though, you’ll need a CAT6 capable smartphone.
Right now, the only two available on EE are the Samsung Galaxy Alpha and the Galaxy Note 4. The iPhone 6 and 6 Plus support CAT4, but not the newer CAT6 standard.
Commenting on the service, uSwitch mobiles expert Ernest Doku said: "It's fair to say that most consumers are only just getting their heads around 4G, and now it looks like 4G+ is here.
“With the world's fastest mobile speeds now available in London, the UK can finally jostle on the world stage as a leader in connectivity.”
Doku added: "It's a unique opportunity for EE, putting them in an exclusive position within the market and allowing the network to flex its 4G muscles and make the most of the spectrum at its disposal.
“While it only covers a small area, and a small range of devices, it's an exciting start for 4G+ and proof of concept for those lucky enough to work in the Square Mile.”
EE has also confirmed its standard 4G network has been extended to a further 19 locations, namely Alexandria (Scotland), Banbury, Biggleswade, Blaydon, Catterick Garrison, Cookstown (Northern Ireland), Garforth, Greenock, Holmfirth, Limavady (Northern Ireland), Maltby, Oxted, Penicuik (Scotland), Tring, Waltham Cross, Warminster, Warwick, Winterbourne, and Ystrad Mynach (Wales).
The additions bring the total number of towns and cities served by EE 4G to 300.
