After this, at software Mobile Parner appeared connection type "ndis" which makes local area connection instead dial-up. The thing is, I do not want use Mobile Parner as it disables "show windows contents" option in Windows.
Anyway, if I do not run this software, under "Network Connections" the Huawei 3G card shows as "network cable disconnected". It only connects if I connect with Mobile Partner.
I'd like to get the internet work now with MWconn, so I put in information as follows:
At Device tab i choose: Huawei
Serial port: COM8 (did try also COM7, didn't work)
APN: internet
At Connection tab: Connection mode "network, manual" and put in "HUAWEI Mobile Connect - 3G Network Card", "Use NDIS commands".
It tries to connect and I see it recognizing my network provider name. Then it will say: connection error 1 - which means as I understood that network card is not found.
Is there any way to get this working? What should I try? To put something in Service terminal to enable network card first? But what??

edit: inside connlog.txt I found:
2010-10-24 16:51:10'21 Selected operating mode: UMTS.
2010-10-24 16:51:24'41 Connection refused. Error 1.
So that means, need to input some extra commands? If I make connection with dial-up it is working. Only network connection will not work.
