EE is expanding its 4G LTE connectivity to cover major road and rail commuter routes in addition to 18 of the airports, ramping up its 4G coverage to improve the LTE service quality for business travellers and visitors.
Being carried out as part of pledged £275m investment in 2014, EE switched on 4G in additional 14 towns including Hartlepool, Torquay and Keighley, bringing the overall connected towns and cities to 174, representing 70% of the UK population.
In addition, the UK internet service provider introduced 4G in 18 of the UK's largest airports including Heathrow, Gatwick, Stansted, Luton, City, Birmingham, Manchester, Edinburgh, Glasgow, Newcastle, Liverpool John Lennon, Bristol, Nottingham East Midlands, Leeds-Bradford, Belfast International, George Best Belfast City, Robin Hood and Blackpool airports.
EE will also roll out 4G coverage along railway connectivity from London Euston to Birmingham, on to Manchester, Liverpool and Glasgow, as well covering London Victoria to Brighton towards the south.
EE CEO Olaf Swantee said that more towns right across the UK now have access to the country's biggest 4G network, and more people can use it where they need it most - in airports and on the busiest commuter routes.
"We are leading the way with 4G, with twice as much coverage as any other provider, connecting more customers in more places," Swantee said.
"But our network investment in 2014 is not just about giving people faster mobile data - phone calls are still an incredibly important part of the mobile experience, and we're investing to ensure that people travelling all over the UK can make phone calls in more places and with better quality than ever before."
EE is also investing money in enhancing the quality of phone calls for commuters using routes from London Euston to Glasgow Central and Edinburgh Waverley to Glasgow Queen Street by summer, while routes from London stations to Bristol, Nottingham, Southend and Cambridge by late 2014.
Motorists on popular UK roads including M25, M1, M4, M6, M8 and M74 will also enjoy improved phone call quality and reliability by summer, with M3, M5, M40, A1(M) and M62 to be covered by the end of the year.
