So indeed buying a sim card at BKK airport is very easy. There are a couple of smaller booth in the bag claim area, and in the public arrival area each provider has a store giving you more choice. They offer only tourist plans, AIS was 299 bath for 3.5GB and 3GB or so, including 30 bath credit.

The other provider are similarly priced, TRUE will give you more GB though.

In the lowest level there is the train station. A lot of pocket wifi renters there, and there is one AIS reseller that gave me 15GB for 7 days including 30thb credit at 269 thb. Apparently it is capped at 4mps download speed, but I found it decent for my needs. In my quick search it was the cheapest I could find BKK airport, and convenient if you need to take the train Anyway.

You can find the store by passing the ticket booth on the left side, continue to walk a bit and you will find it on your right (look for a bright green booth).
