He also said that Congress must be asked why state-owned BSNL and MTNL turned loss-making entities during the UPA regime.
Addressing a press conference here on the call drop menace, Prasad said he is clearing the mess left by the Congress-led UPA government and during their tenure the Sanchar Bhawan - the seat of Telecom Ministry - was known for all the wrong reasons including "corruption, loot and impropriety".
Congress General Secretary Shakeel Ahmed had said it was becoming difficult to talk on mobile "for even five seconds" and the problem was more in the networks of state-owned MTNL and BSNL.
Responding to the Congress' charge, Prasad said, "Call drop is also a legacy of previous government. We inherited it. The weakness in telecom sector that came due to lack of monitoring...Call drop came from other factors... Lack of network improvement, optimisation of network equipment."
The Minister added that BSNL and MTNL were making profit in 2004 till the time the then NDA government was in power, but the two firms became loss-making in 10 years of the Congress rule.
