Very good network speed whole day very littlebit disturbance in day and evening hours, its daily limitation of 1gb is good enogh but if u want some more then dont sleep 2 am to 5 am with awesome speed and no limit after that 1 gb limitation will be applied.
Only problem is voice talk on another network, in which call cant connet very soon, you have to try so many times to talk any one.
Charges are free till 31mar 2017 so not to worry about it now.
Enjoy jio.
