DoT is considering a proposal to allow Mahanagar Telephone Nigam Limited (MTNL) to become a pan-Indian operator. The communications ministry is also learnt to be in favour of allowing MTNL to expand beyond two circles in a bid to improve its falling profits. According to sources, DoT had asked MTNL to submit a list of proposals, including the option of expanding to other telecom circles, as the state-owned telecom firm has been losing momentum in the two metros. MTNL has reportedly submitted a plan regarding this to DoT.
