Hey, guys I am using jio during 1 and the half of year and I am pretty satisfied from there service and there plans which are very reliable.
At first there was no signal in my area if I go on the roof top then it catches only 1 signal but the strenght of the signal was really great it was giving me 1 mbps in 1 signal bar.
But when they are starting there premium plans after march they really install a tower in my area now they given me full tower .
I think worlds cheapest internet and calling plan is only given by jio. For jio we dont have use only 1 gb of net during a month. Now the time change and we can now use daily 1 gb of data free call across india and just we have to pay 399 for 70 days.it really a cheap deal than other operators.
