I have been still used Jio sim when Jio offer started. This is the awesome sim ever invented by Mukesh Ambani and his team. Thank you so much Sir. This is the record for India. Many people still used now for their different purpose. But I also used this sim only entertainment and study material. I am totally thankful for Reliance Jio. The network is so strong and the speed is so good 3-4mbps/second. Jio voice call is so smooth with HD voice. Now Jio has no charges and billing but since 1st April, 2017 Jio users only pay 100 rupees for extended internet period still 30 June, 2017. Thank You
