New Delhi, Oct 1 - Telecom service provider Bharti Airtel today moved the Delhi High Court against the Department of Telecommunication's (DoT) notice asking telecom firms to stop intra-circle 3G roaming services. In its petition, Bharti Airtel said the "decision of DoT is against the public interest as it adversely affects the interest of the customers and the subscribers who are benefiting from the 3G arrangements."
