I bought the jio sim few days ago. I am not fully satisfied with this sim.when I start calling to my contacts it show busy when I try 5 to 6 time then I can call to my contacts. its internet connection is also too bad. it give the speed of 100 kb around in day time and 1 to 2 mbps around in night time . it name should be reliance 2g instead of 4g.
its advantage is you can play the video at any time without any buffering
