Hi, I am using reliance Jio from last october.Jio have very poor network across india.they have not optimized their network just a single time and they have launched their network for all.Now a days congestion of network is very high.If you want call any other network then minimum you have to dial or attempt your call more then twice or more then that.If you are able to make a call in single attempt then you might be luckiest men in this india.VOLTE features of jio is seems completely failed. If you have jio number and you have query related to your number then you can’t be able to speak with their agents even I have tried hundred times but I am not able to speak with them. Charges and billing is not started yet that welcome offer just pulling or increasing the user of Jio. Charges seems cheaper then other telecom operator.i am just suggesting you all if have Lte/4G smart phone then you can use jio free of cost now a days and enjoy free internet and calling.
