Very true...by upgradeing outdated 2G network to Full 4G they can also reduce or save High Running n maintenance cost of their whole network ...bcz running cost of 4G network is very less as its IP based network...but they will not end 2G bcz they want IUC and want To earn extra money from customers...Why we still pay IUC. Airtel,Voda-idea already made 10x of their investment in their decades old 2G Network. Time to scrap their 2G network. Now Airtel,Voda-idea should tie-up with some phone manufacturer to provide cheap Jio Phone like 4G feature phone with bundle offer under 1500.
