These kind of things only happen when companies don't except new technology to match with private companies.
See when Jio and Airtel is testing 5G BSNL is starts providing 4G that's also in phase manner.
And, you'll not believe that their 4G Sim is costing 20 rupees for customers who are upgrading from 2G/3G to 4G.
*Slow Clap*
It's a chicken and Egg problem. MTML employees and their Union will say Govt is not providing money to buy new equipment whereas Govt will say why should they give more funds when MTNL cannot reduce loss even when MTNL was given money earlier.
