Problems with mobile used as a modem

[choltermann]

Hello!

For some time I have been trying to use my mobile as a modem. It is a Samsung Galaxy i7500. It is possible to access it as ttyACM0. I tried kinternet and at last wvdial. None of them worked but with the latter I got some output I could work with:

My provider is o2(germany) and the mobile is from o2, too. I wonder
what the ptoblem is for a lot of people wrote about how easy it
is setting up a mobile as a modem.
The mobile is comnected by Usb.

Thanks for your help,

You created wvdial.conf file manually or using wvdialconf ? Setting up connection using wvdial is very easy, no doubt about that.

Hello !

I first called wvdialconf to create a new configuration and then modified it according to instructions I found in the internet. Neither worked.

But the modem is showing another strange behaviour :
Just now i restarted wvdialconf and it gets stuck at some point (output below).
When I use minicom at some point the modem stops reacting to any command.
I disconnected and after reconnetion the device was shown as ttyACM1 with
ttyACM0 still being there but disfunctional.

It seems to me to be a problem with the software of the mobile. There is
a software update available but only with windows-installer. Maybe that
will solve the issue.

best regards,

C. Holtermann
