Competitors including Bharti Airtel Ltd. and Vodafone Group Plc.’s unlisted Indian unit have also cut tariffs in response by as much as 67 percent and added fourth-generation, or 4G, services in an effort to prevent customer defections. Vodafone said earlier this month that it will write down the value of its unit in India by 5 billion euros ($5.3 billion), and that it won’t proceed with a long-planned initial public offering of the business until at least the end of March.Users of Reliance Jio are entitled to free calls and data till the end of March, Mukesh Ambani announced today.
