Jio-Today’s India’s one of the largest providers of 4g network.It not only gives us a fast 4g network but also in a cheaper rate! Jio can be credited for the revolutionary change in data rates history! Yes it is responsible for 1.5 gb/day from 1 gb/month! Not only that it also provides a absolutely unlimited free calls! Talking about its failures then it has a slower internet speed then promised{ 50mbps-75mbps} which actually about 5 -10mbps. But we should remember that it is a new network provider means it has a lesser no. of towers! so in future the speed of jio is going to increase!
