Vodafone attracted 29,000 new broadband subscribers between April and June 2017.
This takes its overall number of broadband customers in Britain up to 245,000.
The company also confirmed that its 4G population coverage reached 97 per cent during the second quarter of the year.
Vittorio Colao, Group Chief Executive of Vodafone, hailed the figures, saying the provider has made a "good start to the year".
"We are gaining profitable market share in broadband, and a growing proportion of our customers now take our fully converged offers," he commented.
This comes after Vodafone pledged to invest a further £2 billion in its network and services over the next three years.
The commitment follows a comparable level of investment by the company since 2014.
