I was very happy as I was going to take jio sim , but after I got it and its services activated . I found that it is not working good as it had promised to be . Whenever I try to call to any no , it says network busy , and call is not connecting to the other party . I am not able to talk to my friends even after getting unlimitted free calling for 90 days . Only its net is working, but only data service is not sufficient . Its customer care service is also worst , I am trying to connect to customer care from last 7 days but call is not connecting , it remains on ivr only . Finally I say that it is a bad network and service offered by jio.
