I bought this jio sim after being suggested by my friend because of its offers, it made a revolutin in the industry by rising top in just a short span of time because of all unlimited data and calls . but we dont get any network in village areas or in travelling times. but as per the speed it is growing now it wont be a problem for a long time. I’m now using its offer of 399/- unlimited calls and 1gdb data for a single day for 84 days, it is the same rate when I was spending same amount on data for 3g for a month of time in other operaters.
