I arrived after midnight, but they were able to help me without any problems. If you don't have internet access before buying a SIM card, I recommend taking a screenshot of your voucher beforehand. (I couldn't open KKday after arriving at the airport, so I took a screenshot of the voucher's QR code beforehand and was able to show that to them.) After showing it, the staff at the store will handle the entire SIM card exchange process. It only takes about 5 minutes.
