I m using reliance jio from last 2 months and I have noticed may think .the vary first thing is network problem . There is not a single signal of jio network in my home . Even there is very weak network on the roof of my house . So it is the big failure in case of network . Its coustmer service are very sad as they didnt reply of our email and we got only 2-3 min of taking after be on the line for 30 mins .it is apprecitable in case of charges and bill as they provide free data and calling facilities .
