There are three major carriers (AIS, True and DTAC) are selling SIM card for traveller at gateway of Thailand, Suvarnabhumi Airport.

It may be not necessary to speak any word, you just need to point plan of subscription

Very clear for subscription

I picked up 1GB data package with THB100 bonus for making call. Buying SIM card may take less than 5 mins. You just need to bring your passport and cash.
Shop staff helped setting your device.

3G service only, but stable speed.

TRUE provide 4G service, but my device is iPhone4s. There is no point to choose 4G SIM card. I haven't any problem using with 3G for searching restaurant, shop and bus route.

Google Map is the best partner for choosing bus in Bangkok.
