T-Mobile web 'n' walk UMTS-Karte II and Fedora 15

In this article I will describe how you can get the

"Option GlobeTrotter EXPRESS 7.2" aka "T-Mobile web 'n' walk Card Express II"

UMTS/HSDPA Express card with a German T-Mobile subscription to work with your favourite Fedora 15.

After plugging it in lsusb prints:

Bus 003 Device 003: ID 05c6:1000 Qualcomm, Inc. Mass Storage Device

and it will present itself as cdrom drive. If you're on a Windows box you may find useful drivers on a virtual cdrom.

Install packages

yum install ppp usb_modeswitch

usb_modeswitch

For some strange reason it won't work with the default usb_modeswitch installation, so do it manually.

Create the following file "usb_modeswitch_custom.conf" with this content:

# Configuration for the usb_modeswitch package, a mode switching tool for
# USB devices providing multiple states or modes
#
# This file is evaluated by the wrapper script "usb_modeswitch_dispatcher"
# in /usr/sbin
# To enable an option, set it to "1", "yes" or "true" (case doesn't matter)
# Everything else counts as "disable"


# Disable automatic mode switching globally (e.g. to access the original
# install storage)

DisableSwitching=0


# Enable logging (results in a extensive report file in /var/log, named
# "usb_modeswitch_" (and probably others)

EnableLogging=1

Use

to switch the card into modem mode.

ppp configuration

# ispnumber
'OK' 'ATDT*99#'
# ispconnect
'CONNECT'

run

cd /usr/share/doc/ppp-2.4.5/scripts
chmod +x pon
chmod +x poff

in this dir use

./pon umts

to connect and

./poff umts

(at the end of your internet session) to disconnect.

Routing

Then delete default route.

ip route del default

and add default route for interface:

ip route add default via 10.64.64.64

DNS

Make sure you got a correct DNS server in /etc/resolv.conf.

For instance:

208.67.222.222
208.67.220.220

Remaining questions

  • Why can't the NetworkManager deal with the card / modem ?
