But still just 7% of customers on high speed serviceBritain’s biggest mobile operator EE has passed a 4G milestone, with its number of users exceeding two million – double the number of just four months ago. It means EE’s current 4G subscriber rate is now the second fastest in the world, behind South Korea. Strong demand for the high speed service from small and medium enterprise customers is helping to drive take-up, though 4G adoption across EE’s full spectrum of customers remains stubbornly low with just seven per cent of its 27 million customers on plans.
But the flip-side of the picture is that, while convincing users to upgrade to 4G is taking time, it is nevertheless helping to drive EE’s data use generally.
Last year  this was up 70 per cent, mainly due to social media and video downloads.
Meanwhile EE is investing some £275 million in voice services, having identified it as a key feature to growth.
EE, which owns the Orange and T-Mobile brands, was the first UK carrier to launch 4G last year, ahead of rivals Vodafone and O2.
