Airtel SIM card registration failed

My name is Jagadish..Last week i have converted my Airtel prepaid account to Airtel postpaid.

Now today morning onwards, my mobile is not working... It is throwing a message like 'SIM card registration failed". I have called customer care several times. But there was no proper response.

Please do the needful.

Company: Airtel
Country: India
