It looks like Uninor is a quick learner. Uninor picks up fast from top boys of the industries and follows their steps.
As we can see, Uninor is going to charge when you like to speak to Uninor Customer Care executives in Kolkata circle w.e.f. 9th September, 2011.
I did not get information from other circles, but I guess this revision is coming to all circles where Uninor is operating in coming days, sooner or later.
