I own an airtel life time connectionl No.9896556601 which I use for internet connectivity on my PC. I use data cable for data transfer from my handset to PC. This No. is not used by me to send or receive calls because even if I receive a call from somebody the connection is disrupted consequently the PC is to be restarted for reconnection. It also happens in such case that PC does not respond to restart mode and I have to abort all programs by switching off power. This causes a lot off harassment and loss of time.
