Bolstered by a strong performance by its Indian subsidiary, the British telecom major Vodafone Group on Thursday reported a 10.3 per cent jump in revenues to 11.5 billion pounds for the December quarter.

The entity saw its service revenues rise 13.8 per cent to 767 million pounds in India in the December quarter, on the back of a robust customer growth despite a competitive environment.

Vodafone in a statement issued here on Thursday said the group revenues shot up 10.3 per cent to 11.5 billion pounds while services revenues jumped 11 per cent to 10.7 billion pounds in the reporting quarter.

“India’s service revenue increased by 13.8 per cent, half of which was delivered by the network sharing joint venture Indus Towers, with the remaining growth driven by a massive 51 per cent increase in average mobile usage and a commendable 35.1 per cent rise in voice, thus offsetting the revenue decline arising from lower call rates,” the statement noted.

Vodafone India’s service revenue stood at 767 million pounds in the last three months of 2009, compared to 674 million pounds in the same period a year ago.

In the December quarter, Vodafone India witnessed a fall in average voice rates while its “organic service revenue increased sequentially compared to previous quarter,” the statement said.

According to the statement, group data revenue surpassed one billion pounds for the first time, due to increased “take up of data-enabled smart phones across Europe where active data users now exceed 30 million”.
