Iam a Airtel subscriber for many years now, since last 8-9 months i am facing with call disconnection problems both incommnig and out going, it just disconnects in 2-5 seconds, i am not able to make a full conversation ever, i have logged complaints to the Airtel CC, but this have only one thing to say, i.e we have taken the note & the issue will be resolved in 48 hrs, that's it, i have changed my sim card to 32bit/kb whatever,...
