Ever since I had the opportunity of using bmobile‘s 3.5G modem to get mobile broadband (via Zoom!) I was curious to see whether it would work in Linux. After much testing, I did manage to get it to work but it wasn’t consistent (it only seemed to work when the modem was tied to /dev/ttyUSB0, so I kepted plugging it in and out and redialed to see if it worked).

For the newer bmobile modem check out this page courtesy of @jikam

Test system: Running Ubuntu 9.04.

1. Get usb_modeswitch (in Ubuntu / Debian you can “apt-get install usb_modeswitch” which makes things much easier)
2. Get the usb_modeswitch.conf file and put it in /etc/
3. The modem is identified an Alcatel One Touch X020 / X030 / MDB-100HU / Nuton 3.5G (lsusb will show ) so search usb_modeswitch.conf and uncomment the section for DefaultVendor, DefaultProduct, TargetVendor, TargetProduct and MessageContent

4. Do the actual mode switch for the modem to change the device from USB storage to modem mode:
   sudo usb_modeswitch
5. Create the USB serial device for dial up:
   sudo modprobe usbserial vendor=0x1c9e product=0x6061
   This step created 3 devices (/dev/ttyUSB0, /dev/ttyUSB1, /dev/ttyUSB2) on my system.
6. Use the Network Manager Applet to configure a new broadband modem connection with the B-Mobile configuration (APN: bmobilewap)

As mentioned this does not work consistently, so if it doesn’t seem to connection try plugging the USB modem out and back in and retry. I will try find a way to get this more consistent, but hopefully this will help those who are trying to get it to work
