I had been using Reliance Jio for more than a month now and I geet that it is only good for data network that too selected areas in Bangalore. We stay in south Bangalore it works fine in my residence area but where I have my business listed it does not work . Even when I try to make calls to any other Network besides Jio network it does not work most of the times . now Reliance Jio becoming paid service from next month . I really do not know how much this would be useful .
