Reliance jio offers unlimited internet and free calls for three months .but it offers a very crucial speed.which does not match 4g from any side.calls are not connecting in this network.and offers an discusting sound is route ki sabhi lines wyasth hai. It is not an network to trust the services are very.bad.its has low bandwidth with a very high number of users I think reliance should take some steps to improve its speed .personally I admit avoid this kind of networks amd go with airtel and vodafone.!
