Not Connecting to internet through usb modem

Try running:

gksudo gedit /etc/modrobe.d/usbmodem.conf

add the line:

options usbdriver=option usbmodem="1c9e:9605"

Save the new file, reboot to test

Hi,
There was no file usbmodem in /etc/modrobe.d location. So I created one and pasted the line and rebboted as advised by you.

Then I ran sakis3g, as usual, it told connecting (second attemp) -- finally failed to connect.
I am using this line in running sakis3g

--interactive
--nohal
APN="pps3g"
USBDRIVER="option"
MODEM="1c9e:f000"
DISPLAY=":0"
LOCALAUTHORITY="/var/run/gdm/auth-for-iqbal-2G9roT/database"

Good Morning
