Don't know about Malaysia, but no one seems bothered when travelling to Singapore, Mrs. M and I frequently forget our DACs and end up doing them while taxing to the gate on arrival. There are terminals in the immigration all before the gates so you can do the there if you on't have a mobile signal.
