"Legal opinion has favoured challenging TDSAT judgement dated April 29 on 3G intra-circle roaming. DoT has sent [a] petition to [the] Supreme Court registry around a week ago for appeal against the judgement," an official source told PTI.
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.
The judgement had brought relief to the three operators - Airtel, Vodafone and Idea Cellular - who faced a penalty of Rs 1,200 crore for entering into pacts with each other to offer 3G services in regions where they did not win spectrum in the 2010 auction.
Airtel had won 3G spectrum in 13 out of 22 telecom service areas for Rs. 12,295.46; Vodafone in 9 for Rs. 11,617.86 and Idea Cellular in 11 circles for Rs. 5,768.59 crore.
Tata Teleservices and Aircel too had signed 3G ICR but immediately called off their agreement after DoT issued notice to them.
Following the TDSAT judgement, the Airtel, Vodafone and Idea have extended service under their 3G ICR at pan-India level except Odisha.
Reliance Communications also entered in similar agreement with Tata Teleservices to provide 3G services in Karnataka, Andhra Pradesh, Tamil Nadu, Kerala and UP-East telecom Circles.
