I myself using jio from past 6-7 months . I am enjoying with it fully not only bcoz it is free but also it gives me 3g speed on my iphone . sometime it gets slow because of lots of users but its high speed time is at night . at night it give me more than 5 mbps speed through which I download all new released movies: . its call drop is now improved as compared to before 5 months ago . and now its voice quality has also improved a lot. its network is fantastic because it never goes in any part of nagpur city .
