This is a phone from the third class category which means that it lacks software support. The problem is that you need to use a compatible CDMA SIM card before you can actually use its modem. A CDMA SIM card has the same shape as the standard SIM card and they're easy to mix up. Before you can take advantage of the mode, you need to make sure that you have network signal in your area and the drivers are installed correctly on your computer. The drivers can be found on the support CD that arrives with the phone.
