Hai here I am sharing my opinion about reliance jio, it is the fastest growing in the market in present by its unplesent offers to customer that’s it. Personally used opinion is this sim cards only for 4g users not for 3g and basic mobile phones and for calling we have to install jio HD calling service, one of the most thing network is bad in some where, sometimes notfor browsing it also not support to calling so bad network, and you called person and the call reached person was different in sometimes.
