I have purchased Reliance Jio SIM along with Reliance Jio Mobile last month. Reliance Jio SIM has yet to launch but Reliance Jio is giving excellent service for their users. Reliance Jio is offering free unlimited 4G DATA and Voice call for a limited time period, when It will be launched. I am feeling very happy after using their service here in GUNA, Madhya Pradesh. I am using 4G data pack without any signal interrupt. I am very happy with this service of Reliance Jio . My total mobile cost will be recover within 3 month. Love U Reliance Jio .
