Jio 4G is come like new era for telecom services.
Jio services is free till 31st march 2017.
I’m using the jio sim from august 2016, in starting the 4g is super and very fast but after some monts the speed was getting slow and slow regulary may it cause due to load in network.and also a call connecting problem.
But now call connecting issue is almost end, I can call on any number in 1 dial so thats thr better issue solved by jio.
