Alternatively you might be able to (never done this) configure both links with proper metrics, and have them both active at the same time, the broadband one with a higher priority (I think higher priority is equivalent to lower metric) than the cellular one, and declare the (default?) route on the broadband device to be 'onlink'. Which I believe will cause it to be ignored if/when the device has no link.
