I am using Airtel Postpaid for last 2 years. The plans available in Airtel mobile operator is not much attractive now a days. At starting so many offers available for my number. But in recent days I couldn’t see much offers from them. Airtel network coverage is too bad in many places. As an example I am working in Chennai. In my building I couldn’t even attend a call. I have to go away from building and talk. Because of network issue mobile data also wont work properly. Finally about billing I want to share as a Postpaid user I am not getting any trouble with charges and billing.
