"We don't feel the need to develop a separate mobile revenue stream," Darroch, told investors this week at a New York conference.
Darroch was referring the potential merger between NTL and Virgin Mobile which if successful would create the first UK company to offer 'quadruple play' - internet, TV and fixed phone and mobile packages.
"It's something we will watch but we think, with the acquisition of Easynet, we have an infrastructure that's going to allow us to launch a compelling range of products and services," Darroch said.
NTL has also said it may adopt the Virgin brand for its own cable TV service.
Commenting on this Darroch said: "It didn't particularly surprise us that NTL felt the need to move their branding on from NTL and Telewest? given the issues that historically dogged them," he said. "I don't think fundamentally this changes the competitive landscape."
At the conference Darroch also confirmed that Sky plans to launch voice over internet in 2007 - a service Sky's recent purchase of Easynet aides.
"Our product offering will continue to develop quickly over the next couple of years," he said. "In 2007 we will integrate our internet protocol delivered video on demand offering as well as a true voice over internet protocol product."
