EE added another 1.7 million 4G subscribers during the first quarter of 2015, it has been revealed.
The broadband provider increased its customer base to 9.3 million, up by 224 per cent on the equivalent point last year.
Some 96 per cent of new EE connections made during the quarter were on 4G, with 50 per cent of subscribers taking advantage of the firm's double-speed network.
EE noted that, as of March 2015, more than 7,700 medium and large-sized companies were using 4G mobile services.
"During the first quarter, EE continued to execute well on our strategy to maintain commercial leadership, deliver operational excellence and create long-term value through network leadership and innovation," the service provider stated.
"We are successfully attracting customers to our super-fast 4G network with a net increase of 1.7 million 4G connections in the quarter, more than any other operator in Europe."
EE said it is firmly on-track to reach its target of 14 million 4G customers - over half its mobile base - by the end of 2015.
The firm said it is continuing to monetise its mobile broadband experience, with nearly all new and renewing customers now selecting 4GEE plans.
"Our increased strategic focus on maximising connections on our network, by introducing new connected products and services and cross-selling these into our existing customer base, is delivering for the business."
