I try to use Network-manager in GNOME to dial a mobile broadband connection. My provider is China Unicom, and no username and password is need. But when I complete the setting and try to dial, a dialog is showed to input a password. If no password is inputed, the button for connecting is not enabled. How can I dial a mobile broadband without any password in the Network-manager? Would you please tell me the method? Thank you very much!
Mobile Broadband services that do not check username and password are quite common - they rely on authentication via the SIM card instead.
I have not tried to do this with Gnome but one thing I have done with other OSs is to put in a dummy username and dummy password. Something as simple as user, and pass, works with some providers I have used.
Perhaps if you enter a dummy value, the connect button will activate? Ron
