BSNL
No Connectivity

I have BSNL mobile connection for last two years. i used ADD-ON post paid connection.

I stay at near Water tank, Chandannagar, Pune-Nagar road area.

In our area connectivity is the big problem. I stay at ground floor and i put my phone in window for range.

and for receiving any call i have to go to outside the home.

Can BSNL not have to give good service like IDEA, AIRTEL or any other competetor.

other network given full range anywhere in my home...? then why not BSNL
