Which 2G Band (900/1800Mhz) was sold during 2G spectrum scam?

During the 2G spectrum scam in 2008, the 1800 MHz band was primarily involved. The scam involved the allocation of 122 2G spectrum licenses in this band at prices fixed in 2001, which were significantly lower than what could have been obtained through auctions. This led to allegations of corruption and a reported loss to the government of approximately ₹1.76 lakh crore12. The 900 MHz band was also used in India but was not the primary focus of the 2008 scam3.

In summary, the 2G spectrum scam mainly involved the allocation of licenses in the 1800 MHz band.
