first install the modem drivers from the nokia cd then you have to make dialup internet connection from phone and modem options in control panel of your pc, as i am in office so cant access the ideafresh.com portal, there whole information about setting is given, still if you are facing problem, and you are sure you made the dialup connection right.
here is how i solve it
first connect to internet through phone and then activate the connection from pc, you will get error, now close the connection from the phone and then from the computer, and then from computer try to connect again, this time i suppose it will connect
