Strange, I thought I was the only one facing an issue with the BSNL 3G
service. I am facing similar issues on a iPad.
The connection drops randomly and switches over to Edge. However the
connection returns after a couple of mins.
AFAI have observed, the issue is intermittent, and appears on my
mobile phone as well, so I believe the problem is not with the system
(laptop/iPad/mobile/the OS) but with the service.
