EE has become the first 4G mobile operator to reach the ten million customers landmark.
The company - which became the UK's first 4G provider when it launched super-fast mobile services in October 2012 - has the continent's largest subscriber base.
EE's 4G mobile services are now available to 87 per cent of the UK, with double-speed 4G accessible in a number of major urban areas.
As the firm's 4G coverage increases and more people sign up for next-generation mobile services, total 4G traffic is eclipsing that of 3G on EE's network.
The broadband provider said that, since the introduction of super-fast services, data usage in rural parts of Scotland has increased 60 per per cent while usage in rural Wales is up 50 per cent.
It claimed that said rural areas are "benefiting significantly" from its rollout work, as mobile connectivity becomes more widely available.
Olaf Swantee, EE’s Chief Executive Officer, said EE pioneered 4G in the UK and is "determined to keep the country at the forefront of innovation".
"We were the first to launch 4G+, and the first to introduce Wi-Fi Calling in the UK," he noted.
"We are bringing our 4G network coverage to where it is needed most - enhancing the quality of life of people who live in the most rural and underserved parts of the country."
Mr Swantee added that EE's network advances have "truly unlocked the power of the mobile internet", so much so that customer usage is doubling.
He predicted that EE's network - which is built for capacity - will comfortably handle more than an Exabyte of data per year by 2018.
This is triple the amount of data it carries today, and 16 times more than EE's 3G network handled in 2012.
It is the equivalent of streaming 38,000 years' worth of HD films.
