I have been using airtel for the past 2 years when I was in mumbai airtel network reception was I wont say great but good. I used 3g there and was working fine. In some areas the reception was fairly poor still I managed.
Now I have moved to Kolkata and Airtel here is pathetic. As airtel says they are upgrading the cell phone tower every hour and promises to be open to the customer but I dont see that happening. I stay in a location ( hooghly) where not only 4g but 3g reception is also poor. When I am outside my home the 4g reception intermittently connects and disconnects everytime and half the day it show suspended. I checked on the airtels official webpage about the network it says my location should have good 3g reception and 4g is poor but I dont see my phone even connects to 3g.
I switch my phone to 3g mode it connects to 2g and when switched to 4g it says suspended or sometimes say connected but no internet.
I am on an unlimited calls and 1GB data per day pack for Rs 399. I guess my money is flushed into the gutter. I trusted Airtel as I got good service back in mumbai.
Call centre reps are also not very knowledgeable about what they are working for. I ask one question they say everything jibberish but will not answer your question. And not only I whos is facing this issue there are alot of airtel customers complain about the same thing. I have made a complain via email to airtel and its been more than a month I havent heard from them since.
