Nothing is free in the world.butjio give us a best quality 4g internet with any hiding cost.Jio give us 4 gb daily internet since 5th sep to 31st december 2016.than jio give us new offer 1 gb daily till 31 march 2017 now after this who prime member get 4 month free data only 303 rs.
Jio network is now getting better day by day because they are working on network.initialy state jio networl was very big but noe jio covers approximately whole india.jio provide good speed because of good network.
Customer service of jio is not good because if you have any problem than every time jio customer care call did not connect .and also much waiting time always it holds the customers.
Charges and billing if we dont talk about that than it is good because jio gives the 7 month free service after only 303+ 99
Rs it again given the 4 months service with daily 1 gb data.so jio is very cheap and very effective.
According to me jio gives the freedom to user freely jio.
