How best to activate a mobile internet modem/ SIM card @ Kubuntu Karmic?

[Bas Roufs]

Hello Sinclair and Everybody
> it is called the APN for TMobile (or whatever provider). Internet searches ...(SNIP)
The keywords "APN T-mobile NL" enabled me to find all the codes we
need from the provider T-Mobile NL

Phone number for access to the modem: *99#
APN: internet
Account Name: tmobile
Password: tmobile

One of the websites where I found this info is this one:

Via KPPP I tried to dial into the modem both with the empty space and
with "tmobile" as user.
In both cases I tried the four ports: ttyUSB0, ttyUSB1, ttyUSB2, ttyUSB3.
But in all 8 variants I get a log window feedback like this:

kppp can not find:
 /dev/usb/ttyUSB1
Please make sure you have setup your modem device properly and/or
adjust the location of the modem device on the modem tab of the setup
dialogue.

Sometimes I do get a simpel "error" in case of the user name "tmobile"
in combination with ttyUSB0 - then, KPPP freezes and quits. In such a
situation, I need to restart and quit 2 times in order to get KPPP
running again.

Also attempts to set a connection via "Networkmanager" have been
fruitless so far.

However it may be, I still do not get a working internet connection
from the Kubuntu 10.04 partition in combination with the HUAEI E1820.

So far, I did not yet get the feedback "modem ready" - in spite of
everything I have been doing so far. Moreover: I explicitly take care
of unmounting every time the USB stick before doing anything else.
That's why, I am wondering what exactly to do next.... Is there
anything else I can change in the settings of KPPP with a view to
getting a working internet connection?

Thanks, respectfully yours,
