Rajatkumar, Have you tried the following: ``If your modem is an external USB type, connected by an external serial cable, or mounted internally on an ISA card, then scanModem would not access it. Try with Root permission $ sudo wvdialconf /etc/wvdial.conf to detect these modem types and some USB modems. If the detection is successful, read the DOCs/wvdial.txt . Edit the /etc/wvdial.conf with Root permission: sudo gedit /etc/wvdial.conf will be able to dial out with Root permission: sudo wvdial '' Please try the above advice and report back presently.
