Don Mueang International Airport (DMK) is Bangkok’s primary hub for budget airlines. If you are flying AirAsia, Lion Air, Nok Air, or any other low-cost carrier into Thailand, this is where you will land. The good news is that you can pick up a local Thailand tourist SIM card right after clearing customs, with prices starting at 299 THB (~$8 USD).
However, DMK is a smaller, older terminal than Suvarnabhumi Airport (BKK), and the SIM card situation here is slightly different: there are fewer counters, only one AIS booth, and shops frequently close before midnight.
This comprehensive guide walks you through exactly where to buy a SIM card at Don Mueang Airport, what each carrier charges, and whether an eSIM is a better fit for your trip.

All official SIM card counters are located in the International Arrivals Hall (Terminal 1). Do not look for SIM cards in the domestic terminal, as the selection there is poor and tailored primarily for Thai residents.
🔔 Network Market Update: Thailand now operates on two major mobile networks: AIS and True Corp. True Move H and DTAC officially merged into True Corp in 2023 and now share the same cellular infrastructure. While you will still see both brands at DMK, the network coverage behind them is identical.
You can buy your SIM card from official carrier stores, convenience stores, or pick up a pre-ordered card at a Klook counter.
AIS is Thailand’s largest mobile network and offers the widest coverage outside Bangkok. It is your best pick if you plan to visit remote islands or northern mountain regions like Chiang Rai and Pai.pick if you plan to visit remote islands or northern mountain regions like Chiang Rai and Pai.
📍 Location: There is only one official AIS booth in the International Arrivals area. Because of this, expect long queues during peak morning waves of low-cost international flights.
Opening hours: Not guaranteed 24/7. This counter frequently closes before midnight depending on flight schedules.
Payment: Cash only. This is the most common surprise for travelers at DMK.
What you need: Passport, a carrier-unlocked phone, and Thai Baht cash.
💡 Money Tip: If you do not have Thai Baht (THB), you can withdraw at ATMs in DMK airport. But the charge is 220 THB (~$6 USD) per withdrawal for foreign cards. Thus, you should withdraw enough to cover your SIM card and your taxi fare in one go to avoid paying this fee twice.

Since True Move H and DTAC run on the same network, the only differences at the airport are the branding and the specific plan lineups
DTAC counters carry the cheapest entry-level tourist SIMs while True Move H focuses on premium, high-speed “Infinite” 5G packages

📍 True Move H locations (3 stores):
Opening hours: Officially listed as 24/7 (00:00–23:59 daily).
However, because DMK handles fewer late-night flights than BKK, some booths may close early on quiet nights. True and DTAC remain your safest option for a late-night arrival, but they are not 100% guaranteed past midnight.
Payment: Cash and card accepted at official stores.
What you need: Passport, carrier-unlocked phone, cash or card.

If the official carrier counters are closed or have long queues, there are backup options inside the terminal.
7-Eleven has multiple branches across both DMK terminals. The most convenient branch for international arrivals is located inside Terminal 1 on the 1st floor, right near the exit area.
What they sell: Basic tourist SIM cards from True Move H and DTAC starting at 299 THB. They do not stock AIS SIM cards.
Pricing: Same price as the official counters with no airport markup — but fewer plan options.
⚠️ Note: The staff are usually too busy to help with SIM installation, so you may need to activate it yourself using the instructions on the packaging.
You can pre-order a SIM through the Klook app before you fly, then show the QR code at the Klook/DooCliBook kiosk at the airport to collect. This is handy if you want to skip the queue entirely.
Where to collect: Head to the Klook / DooCliBook kiosk located inside the airport terminal.
Pricing: Prices are similar to counter prices — around $7–8 USD for an 8-day plan with 10–50 GB.

Note that ATM withdrawal fee at DMK (and all of Thailand) is 220 THB per transaction. Therefore, you should withdraw enough in one go to cover the SIM plus your transport into the city.
If your phone supports eSIM technology, you can completely skip the physical SIM counters at the airport. Purchasing a Gigago Thailand eSIM allows you to buy your plan online before your flight, scan a simple QR code, and connect to a local network the moment you land.
This option is highly recommended for travelers arriving at Don Mueang (DMK) Airport to avoid long queues at the limited service booths, or the risk of finding counters closed if your flight arrives late at night.
Gigago is an authorized partner of DTAC / True Move H — you can verify this directly on the True Move H website. The eSIM runs on the same DTAC / True Move H network that powers the airport SIM counters.
The table below compares the cheapest physical tourist SIM available at DMK Airport against Gigago’s entry-level Thailand eSIM plan:

👉 Choose the best Thailand eSIM that fits you needs here:
Not reliably. This is the biggest operational difference between DMK and BKK airports.While Suvarnabhumi (BKK) counters run 24/7, Don Mueang is less predictable.
Even though True Move H and DTAC officially list their hours as 24/7, they frequently shut down early on quiet nights when there are no major low-cost flight arrivals. The single AIS booth is almost always closed if you touch down after 11:00 PM.
If you are landing late on a budget flight, the safest options are:
DMK offers free public WiFi under the network name “@Airport Free Wi-Fi by NT”.
The speed is perfectly adequate for messaging family, looking up your hotel address, or booking a ride via the Grab or Bolt apps. However, the signal cuts off completely as soon as you step outside the terminal doors.
If you miss your chance to buy a SIM card at the airport, don’t worry, Bangkok has plenty of options.
Prices of Thailand SIM cards for tourists are standardized across official stores, so the city price is the same as the airport. The advantage of buying in town is a wider selection and guaranteed card payment.
For most travelers landing at DMK airport, the fastest option is to grab a DTAC or True Move H SIM at one of the five counters in the arrivals hall — 299 THB, 5 minutes, done. Pick AIS only if you need coverage in remote areas and the single AIS booth isn’t crowded.
If you are arriving on a late-night budget flight, buy a Thailand eSIM before you board — DMK SIM shops are not reliably open after midnight, and an eSIM activates the moment you land.
