Service of reliance jio is worst in the world. Neither their contact numbers are working, neither they give proper information to their service centres. I have gone to bought a 4g sim today by seein that yu yuphoria is eligible for preview offer but workers at reliance digital say that they do not have any information about this instead at other places than jaipur stores are giving sim to all eligible 4g phones. Not even a single digital centre contact no works for information. If the starting of jio is like this then I will sure it is going to ruin all expiration of preview offer of users. And also my friend by luck got the sim and it is giving 150-200kbps speed, instead airtel 3g is giving 1mbps speed. So they are making people fool and this is their business strategy to add customers with their network.
