Like many Indian companies, Bharti Airtel is weighed down by loans it took out in dollars, which the depreciated rupee makes more expensive to pay back. The rupee is now hovering at about 61.5 to the dollar, 13 percent lower than its January average.
The company said it had consolidated net debt of $9.7 billion.
Bharti Airtel's profit growth has slowed for several quarters but it is expanding in Africa and Bangladesh and recently passed the 50 million mark for data service customers in India, chief financial officer Sarvjit Dhillon said.
He said that high maintenance and energy costs as well as regulation are increasing expenses across the board in India's telecoms industry and warned that rate increases might be inevitable because of the weak rupee and India's high inflation.
