The PIL also alleged that Jio was allowed to provide voice telephony along with its 4G data service, by paying an additional fees of just ₹ 165.8 crore (US $26 million) which was arbitrary and unreasonable, and contributed to a loss of ₹ 2,284.2 crore (US $360 million) to the exchequer . </P> <P> The Indian Department of Telecom (DoT), however, refuted all of CAG's claims . In its statement, DoT explained that the rules for 3G and BWA spectrum didn't restrict BWA winners from providing voice telephony .
