I am using Jio sim card its network is very bad. network has not present where I live Mahada(HDIL) Kurla west whole days. I brought WI-FI with the help of WI-FI we talked to any person from the mobile without WI-FI we can not talk to any one from the mobile.
Nowadays The Reliance Jio company increase the amount of all package. They are not improve network flow system only increase the amount of package. it is true mostly people of India are using sim card Reliance Jio but it is also true that the network of Jio sim card is very bad the network is present at some place and not a other place.
