Here we go again! Calling rates continue their downward path in India as Bharti Airtel announced yet another price cut for its pre-paid customers in Delhi and NCR circle. By recharging their prepaid accounts by using a voucher worth Rs 56, subscribers will be charged 50 paise per minute for all local calls. This offer follows an earlier price cut that had set local outgoing calls at Re 1 per minute, following a TRAI recommendation.
