Feb 5 (Reuters) - Bharti Airtel BRTI.NS, India’s second-largest mobile carrier by number of users, posted its seventh straight quarterly profit rise on Thursday, as subscribers upgraded to higher-margin telecom plans amid a steady rise in customer base.
The firm's consolidated pre-tax profit rose 34.4% to 125.58 billion rupees ($1.39 billion) for the quarter ended December 31, from 93.46 billion rupees a year earlier.
Airtel's year ago profit included a net exceptional 75.5 billion rupee gain, mainly from a higher valuation of its stake in telecom infrastructure provider Indus Towers INUS.NS.
