wvdial says modem is recognized and is working(on Windows i am using it already).

Please help me to use this modem in theses three ways to connect to internet.

you should set up a 'mobile broadband' connection with appropriate settings.
Is it seen as a modem or storage device?
usbmodeswitch?

dear mani,
already mobile broadband connection is set.
but ididnt touch"usbmodeswitch"
how to do it? plz explain me.

thank you

In /etc/ppp/options there may be

lcp-echo-failure 4

change it to

#lcp-echo-failure 4

usb_modeswitch does not seem to be necessary.
Anyway post output of lsusb

Dear mani

please gothrough lsusb output as well as dmesg | tail for TATA PHOTON WHIZ
