I recently got reliance Jio sim. On Samsung galaxy S6 device. I see the speed is very good on all google services like Google drive, Dropbox and other. when I download from the google drive speed is very high like 8/10 MB per second.
And other website gives slow speed like 700/800 KB per second. and it give Unlimited of data uses. so pretty. It offer a unique combination of telecom high speed data, HD voice calling, and SMS. Its supports Volte service that means Voice over lte(Hd calling Fetcher). It give 3 months Unlimited Data, voice and sms service. And also reliance JIO launches website for its lYF handset for searching LYF handset.
