I am attempting to set up some 9470 Ultrabook units with mobile broadband. The cellular card is installed, and when I attempt to inset the SIM card into the desinated slot under the battery, it doesn't seem to work as expected. There is no 'tray' or spring loaded mechanism to eject the card. Also, there is nothing that indicates the card is inserted correctly. I can literally insert the card in any orientation, but then it is unretrievable.
Is something missing here?
