if the sim tray is jammed, it could be that your sim card is not working either and if you're not connected, you wouldn't get any updates. the device will have to be taken apart to fix the tray if it is fixable. most people would charge 50-70 dollars to do this. there is risk at breaking the glass trying to get it off so it takes special tools and use of heat.
