This service came with a revolution in communication world after getting it I just don’t need to recharge my number again again and again just open the jio4gvoice call wherever you want but there, is a little condition after 30 min of talk it will be disconnected and then you need to call again even it can call where some special charges are applied, for free and one more important thing is that if jio4g are not in network then this will not work untill the network come through it means it works with internet but overall service is very good.
