As we all know Jio is one of leading network operator .they providing free unlimited 4g data and call.but speed of internet is not like 4g.other network providing same speed in 3g.but what can we expect in free of cost.As we know offer is extended till March with limit of 1gb data on 4g per day.but this 1gb data will end only in few hours.how can it possible 1gb data is end only with 1/2 hour of YouTube video.this is my personal experiance .things is they just giving you fake promises to increase there customer.
