After postponing the 3G spectrum auction twice, the government still has no time-line for conducting the process to introduce this high tech mobile service in the country.

"We don't have a time-line (the fresh date for 3G spectrum auction), the cabinet note for the process is being sent. I cannot comment on the time or the price for bidding," Telecom Secretary Siddhartha Behura said at an ICRIER event here.
