Jio network is very low cost.
I take jio sim 1 year ago. Now I said it is a best .
Jio data speed is also too good. I got 6mb/s in download spped. It upload speed is too good. Now I use jio for data or calling. But calling problem still avalible. It request to other network operator to fix this problem because they make this problem. I also request to airtel to dont make us fool.
