These counters are located in the arrival hall and are open 24/7, so you can get a Thai SIM card no matter when your flight lands. The staff will assist you with setting up the SIM card, so you’ll be connected within minutes.
At Convenience Stores (7-Eleven and FamilyMart)
There are 7-Eleven and FamilyMart convenience stores located within Suvarnabhumi Airport in Bangkok. They can be found on the 3rd floor, between the arrivals and departures areas, and also on the lower levels, close to the Airport Rail Link. These stores are convenient for both arriving and departing passengers needing basic necessities, snacks, or drinks.
If you miss the chance to buy a Thai SIM card at the airport, you can easily find one at 7-Eleven or FamilyMart. These convenience stores are located all over Thailand and are open 24 hours a day. Simply ask the cashier for a Thai SIM card, and they will help you activate it.
