Share prices of telecom stocks fell on Monday, the first trading session after Reliance Jio announced a new plan exclusively for its Jio Phone users. Reliance Jio is offering free voice calls and unlimited data at `49 for a validity of 28 days. The announcement was made post-trading hours on Thursday. The shares of Idea Cellular, Bharti Airtel, and Reliance Communications fell by 1.63%, 2.66%, and 3.88%, respectively. The BSE Telecom index fell by 1.18% and ended the session at 1487.65. Last week telecom stocks fell after Reliance Jio decided to offer 500 MB extra data to its subscribers using 1GB and 1.5GB per day data packs. The move came after Bharti Airtel introduced its Rs 399 plan, offering unlimited calls and 1GB 4G data daily with 84 days validity. In a note, to investors, Kotak Institutional Equities said Reliance Jio's aggressive competition could continue until it reaches unspecified market share, revenue or profit targets.
