Vodafone, reporting its third-quarter results on Thursday, said it was also seeing lower rates of growth in its global enterprise division, and said it was taking a more disciplined approach to agreeing contracts.
In addition to strain across its Indian businesses, its major United Kingdom market also reported a fall in revenue, as the company continues to face the effects of "heightened price competition" against its rivals.

Vodafone are now in talks with Aditya Birla Group to negotiate a potential merger between its Indian division and Indian Idea.
"We have had another strong quarter and continue to see positive momentum across our customer base, which reflects both the ongoing strength of our core mobile and broadband business, as well as growth across our converged service offerings", said Vodafone Ireland chief executive Anne O'Leary.
Vodafone confirmed its outlook for the year, saying it expected to meet the lower end of its forecast for earnings before interest, taxes, depreciation and amortization.
