Worst app. I couldnt even able to get my barcode.It was not showing get jio sim option. I got jio sim somehow and when I try to login my account with jio number or email id it shows invalid id or number and invalid password. Sometimes it takes a day to get One Time Password so that we can arrange new password. We need to install the app to know our jio sim usage but I dont recommend. slow loading on lowend devices.
