I think nameserver may vary from operator to operator(i use Vodafone India)
and also when i ping google, it finds the IP to be connected correctly(i
test that ip in web browser of my PC). So I think it(DNS) may be correct.

for the gateway: i have removed the default one with(route del default) and
added a new one as (route add default gw 10.64.64.64)

So, now it becomes like this :

debian-gta02:~# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
10.64.64.64     *               255.255.255.255 UH    0      0        0 ppp0
192.168.0.0     *               255.255.255.0   U     0      0        0 usb0
default         10.64.64.64     0.0.0.0         UG    0      0        0 ppp0
debian-gta02:~# cat /etc/resolv.conf
nameserver 10.11.230.2
nameserver 10.11.230.3
debian-gta02:~# ping www.google.com
PING www.l.google.com (209.85.153.104) 56(84) bytes of data.
^C
--- www.l.google.com ping statistics ---
5 packets transmitted, 0 received, 100% packet loss, time 4013ms

debian-gta02:~# ping 10.64.64.64   
PING 10.64.64.64 (10.64.64.64) 56(84) bytes of data.
^C
--- 10.64.64.64 ping statistics ---
