I m using reliance jio sim to oppo neo 7 from aug 2016 for four months free net, free call, free nessage, free applications. It is true great and good expirience about reliance jio internet service download speed upto 8 mbps. Easy to inernet share with friends, reliance jio application is good and workfull like reliance jio tv. But here is some problem about reliance jio call and reliance jio message. Many times could not call other people. when welcome offee finished then reliance jio tarrif plan very chippest any other network service. Relicje jio’s network frequency volte for this reason download speed better any other network provider.
