configuring huawei e1550

[Luca Ferrari]

Hi all,
I'm trying to configure my internet broadband key E1550 (the provider is 3) for 
internet access on my kubuntu 10.10, but I cannot set up it on my laptop 
neither on my netbook. I know the phone number to call, I know the access 
point (datacard.tre.it) but I cannot see knetworkmanager working. I know 
someone is able to run it thru kppp, that is fine for me, but I don't know how 
to configure it since I don't see any place where I have to insert the access 
point. Moreover, the program keeps saying that it is calling *99# (the 
provider number).
Any clue?

Thanks,
Luca
