I'm not too familiar with this section, hope this is the right thread?
Just got this universal modem as it seems the gsm networks are going into some interesting competition. So i thought it's plug &play universal, just fix SIM and start browsing. So it's plug& play alright in the sense of drivers installation. But i put different simcards, it's saying

[720]A connection to the remote computer could not be established. You might need to change the network settings for this connection.

Please what am i to do?

Any takers?
