EE saw a further increase in the number of fixed line broadband customers during 2015.
According to the firm's latest trading statement, the figure rose by 11 per cent last year to 933,000.
This helped EE's operating revenue remain steady at just over £6 billion, while underlying revenues rose by 1.1 per cent throughout the year.
The increase was also fuelled by strong growth in the number of 4G mobile phone customers, as an increase of more than 14,000 in the final quarter took the overall figure for 2015 past the 14 million mark.
Marc Allera, Chief Executive of EE, commented: "2015 was an exceptional year for EE, as we met and exceeded 4G targets, won multiple awards for our network performance, and improved our customer satisfaction scores."
He added that EE is looking forward to continuing to innovate for the benefit of its customers, as well as building and enhancing the UK's digital infrastructure.
