Vodafone Group Plc has announced its financial results for the first quarter of financial year 2012.

The operator?s Indian arm, Vodafone Essar, posted a 16.8 per cent increase in service revenue, driven by a 29.8 per cent increase in its customer base, stabilising mobile voice pricing in the market and 70.4 per cent growth in data revenue.

As of June 30, 2011, the operator?s data customers touched 26 million, a year on year increase of 189 per cent. The growth was driven by the increase in data enabled handsets and the continued impact of successful marketing campaigns run in conjunction with the sponsorship of key sporting events. Whilst competition in the market remains high, the effective rate per minute is stabilising as a result of a focus on promotional offers rather than further ongoing price reductions.

Following the launch of commercial 3G services in February 2011, 3G services were available to Vodafone customers in 147 towns and cities across 12 circles as of June 30, 2011.
