I am using JIO network since last 3 years and network is so good and improving day by day.
There are some of the steps how's the Jio service quality going on till now.
In starting jio comes with a good network and high speed data and it's free in starting.
As user grows in Jio then network gonna poor and data speed went slow.
After sometime Jio maintain their Network services.
Other companies blame Jio for their loss.
Jio improving their Network.
Now Jio has lot of customer base and still Jio improving himself.
