My observation after using jio
1.i started using it from december 2016 I woul say it has brought revolution in the telecom sector.
2.plan which it offer is very attractive
3.almost every things is free and it has been bundlled in on pack and this was the major reason for the success of the jio.
4.the only problem I face is during the rain there are no internet connection and I am using it in banglore in chokanhalli area.
So jio will have to take care of its network other wise working perfect.
