Address:

North West Delhi, Delhi

Hi,
I am having airtel postpaid mobile no. [protected]..
I am travelling to bhigwan (Pune) on roaming...
There was good network two days ago, from 5th Oct'10 morning all of sudden my network lost.
I tried to change some settings in my Nokia E 63 phone but all went in vain..
I am totally cut off from rest of the world which is badly hampering my business as well personal relations..everybody else with Airtel connection is having good connectivity...
I am in state of shock, can a network like Airtel have such problem
Kindly help..
