I saw an AIS stand in the int'l baggage claim area, but didn't notice TrueMove H or DTAC (they may well be there somewhere?).
TrueMove H has a few automated KIOSKs at their shop on level 2, outside ARRIVALS (and door #4). I think the queues vary based on the number of arrivals? All were quite long this past Tuesday, ~ 06:45.
