The reliance jio nowadays is the most popular thing after narendra modi ji in india.it tells that that voice charge is free through the life time .but the real thing is that after dialling a no. More than 30 times, there is a little chance that the call will be foreword next time.thats too irritating and sometimes funny also.the one thing that I like is the free 4g till 31 december.in my opinion if one should want to buy jio sim then take it only to browse internet not for calling purpose. .
