Data connect fails due to missing DNS

Hello, I have a WP7700 red and I’m Following the getting started tutorial. I reached the point where I’m supposed to run redSensorToCloud in order to connect to the Cloud. However, this didn’t seem to work so I tried “cm data connect” and I figured out that the device didn’t connect because of the missing DNS I checked again and Indeed in the info the two DNS fields are empty(N/A). So I am sure that the sim card I have doesn’t offer DNS. Any idea how can I proceed ?
