Networking :: Datacard Goes Online But Doesn't Gives Internet Access (Fedora 14)

I am using MTS datacard. I have usb_modeswitch installed and have configured the wvdial.conf file. When I do sudo wvdial cdma, the IPs and DNS addresses are also allocated but I still cant access internet.

Code:

dmesg | grep -e 'tty' -e 'modem'

is:

Code:

[ 0.000000] console [tty0] enabled
[ 11.098238] USB Serial support registered for GSM modem (1-port)
[ 11.098352] option 6-1:1.0: GSM modem (1-port) converter detected
