A bench headed by Justice J Chelameswar soughta response on the appeal filed by Department of Telecom challenging the Tribunal's judgement.
Telecom Disputes Settlement and Appellate Tribunal had overturned a government ban on offering 3G mobile services beyond their licensed zones through roaming pacts, saying that it was in national interest to allow better utilisation of scarce radio frequency.
Airtel had won 3G spectrum in 13 out of 22 telecom service areas for Rs 12,295.46 crore; Vodafone in 9 for Rs 11,617.86 crore and Idea Cellular in 11 circles for Rs 5,768.59 crore.
DoT had issued notices to Airtel, Vodafone and Idea on December 23, 2011 asking them to stop 3G ICR within 24 hours but the order was challenged by them.
