Vodafone is planning a major investment in 2015, as the mobile operator looks to make "very significant" improvements to its network.
Speaking to the Financial Times, the firm's Chief Executive Jeroen Hoencamp said it would spend £1 billion improving connectivity in the UK.
Vodafone is conscious of the need to upgrade its network and launch new services - including home broadband and TV - to defend its market position as the telecoms industry consolidates.
With fixed-line broadband providers BT, Sky, TalkTalk and Virgin Media becoming more active in the mobile sphere, Vodafone needs to provide additional incentive for its customers to stay loyal.
Mr Hoencamp said a major priority for Vodafone will be improving its 3G and 4G network.
“Nothing else matters without the network," he told the news provider. "It isn’t as good as it should be and it isn’t as good as it can be."
Mr Hoencamp explained that London will benefit from the deployment of new connectivity solutions, specifically 1,000 new mobile masts.
This will help to create "world-class" coverage in the UK capital, he added.
But the Vodafone CEO said his company is focusing on more than simply improving broadband speeds - it is also looking to bolster voice services.
He said the firm is "exploring every option" as it looks to improve services, adding that Vodafone has "ambitious plans" for the future.
