Last 8-10 months reliance jio is making breaking by time to time. It gave free data and calling in starting time. A lot of people change their mobile operater and move on to reliance jio. But the data speed is not as good as 4G network. calling is good sms service is also good but I am not satisfied with its network speed.at night and early morning the network speed is good but at day time specially between 12 to 5 it does not provide the data speed as expected with it. But overall it’s good to see a Indian company is making such differece in mobile operaters world.!
