Airtel Prepaid
Network problem

I have a prepaid connection and work in magarpatta city pune.. We have 12 company towers here, in which there must be aprox 40 thousand airtel connections but we do not get proper coverage inside the company and beside the buildings, this prob is from a very long time, this connections also include some corporate connection who are facing this prob.. We cant even send sms cause of this network... nw we are thinkng to change the connection, we think idea is better.
