Sky will become the latest UK broadband provider to introduce quad-play deals, after agreeing a partnership with mobile operator Telefónica UK.
In a new multi-year deal, Sky is teaming up with O2's parent company on mobile voice and data services.
Sky will gain wholesale access to 2G, 3G and 4G services over O2's UK network, allowing it to offer mobile packages alongside broadband, home phone and TV services.
The first Sky mobile deals are set to be made available to consumers in 2016.
Jeremy Darroch, Chief Executive at Sky, said his company has a "proven ability" to launch new services at scale, and this is what it will be doing in the mobile arena.
"We know our 11.5 million customers trust Sky to offer them the best quality and choice and have an appetite to take more from us," he stated.
"Through our partnership with Telefónica UK, we can build on our expertise in content, innovation and service to launch a range of exciting new services and exploit the opportunities for growth in the fast-changing mobile sector."
Ronan Dunne, Chief Executive of Telefónica UK, said the firm is "pleased" to welcome Sky to its roster of "innovative, successful partnerships".
He said Sky understands the importance of a strong network and excellent customer experience and has made his company "a trusted partner to help deliver brilliant services".
"This will widen consumer choice still further and demonstrates the lively competitiveness of the UK market. We’re looking forward to working with Sky," Mr Dunne stated.
O2 has committed to offer 98 per cent 4G coverage in the UK by 2017, meaning Sky customers should have widespread access to super-fast mobile broadband.
