Hello Friends, I going to share my personal Experience with "RELIANCE JIO".
I got my JIO SIM on Dated 22.09.2016. in early days I did face much more problems like No Signal, No Network, Not connecting Call etc.
But after Next day, Network Coverage are awesome, mobile data speed very Good(upto 16 Mbps) but still I have facing one more problem that Voice call not connecting I’m very sad with this, and then my friend tell me that please install one app called "Jio4GVioce" whis runs over internet.
Finally I’ve installed that app and configure with jio sim, but now it shows "OFFLINE"
Very Sad.
But Finally, Today I’ve make my First Voice Call through JIO sim, Feeling awesome
So Friends, my suggestion for those who still not have jio sim, please collect you JIO SIM Today from any Store and Enjoy unlimited HD Voice Calling Video Calling as well as 4G INTERNET
