Hi friends, I am sharing my own experience with jio service I must tell you I am really satisfied. Network coverage is very good to compare other network for example Tata Docomo in Telenor. Connectivity is very good sometime the speed demon slow what is still it is good then the other company. Best part of the jio SIM is they provide free calling all India without roaming. Customer service is not great but they doing his best for customer. They provide many app to watch live TV listen music security absolutely free. I recommended all people to get Reliance jio Sim because it is absolutely free and giving best service operator.
