UPDATE 1-India's Reliance Comm raises some call prices, more expected
* Reliance Comm raises some call prices by 20 pct, cuts discounts
* Mobile carriers yet to start increasing base tariffs
NEW DELHI, May 6 (Reuters) - Reliance Communications Ltd , India's third-biggest mobile phone carrier by customers, has raised some voice call prices and further cut discounts, extending price increases in the world's second-biggest mobile phone market.
Until recently, operators in India's fiercely competitive market have offered steep discounts to win customers, often sacrificing margins, but rising airwave costs and heavy debts have forced carriers to end that strategy.
As several smaller firms have either shut down or scaled back operations in response to a court order, bigger companies such as Bharti Airtel, Vodafone Group Plc and Idea Cellular have cut discounts on voice calls, effectively increasing prices.
Operators are likely to further cut discounts and free minutes in order to boost revenue, analysts say. Last week, top carrier Bharti Airtel, which withdrew discounts in January, said it expected pricing to become more stable.
Still, firms will be less rapid to raise the so-called headline, or base, tariffs - currently at between 1.5 paisa and 2 paisa a second - as an overt rise in prices could hit demand, said Ankita Somani, a telecoms analyst at Angel Broking in Mumbai.
"I really don't see headline tariffs going up for the next one quarter or so," she said.
A paisa is one-hundredth of a rupee, or around two-hundredths of a U.S. cent.
Reliance Communications, which is due to report quarterly earnings on Friday, said on Monday it is increasing calling rates to 1.2 paisa a second from 1 paisa in some plans, still below its base price of 1.5 paisa a second.
"With smaller operators shutting down or scaling down their operations and easing off hyper-competitive pressures, this will help pricing power move back ... and positively impact profitability," Gurdeep Singh, Reliance Communications' head of mobile business, said in the statement.
Shares in Reliance Communications, controlled by billionaire Anil Ambani, have jumped nearly 50 percent this year on hopes of more deals with Reliance Industries Ltd, run by Anil Ambani's wealthier brother Mukesh, which is readying the launch of a nationwide 4G network.
Reliance Communications shares were down 0.2 percent by 0729 GMT, marginally underperforming a broader market that was up 0.1 percent.
