Travel eSIMs you may like:
You’re off on an epic Thailand holiday.
Bags packed. Flights booked. Hotels locked in. Get ready for an action-packed adventure of gilded Buddhist temples, paradise palm-fringed islands, and heaving plates of cheap, delicious street food. I’d be lying if I said I wasn’t jealous.
But there’s still one more thing to organise: mobile data.
In this post, we’re showing you how to get a SIM at the Bangkok Airport, whether you arrive in Don Mueang or Suvarnabhumi. We’ll also present an easier way to get connected in Thailand, the eSIM.
INTRODUCING ESIMS
You’ve heard the term online. But what actually is an eSIM? The ‘embedded SIM’ is basically just a digital SIM profile stored on your phone. Instead of inserting a plastic card into the SIM tray, you download the eSIM from a website and install it.
Sound complicated? It’s super simple for the user. Getting set up takes 5 minutes and doesn’t require any fancy tech skills – even grandma could figure it out. Upon landing in Thailand, your eSIM activates automatically when you switch off aeroplane mode.
Almost all newish phones support eSIMs nowadays. See our eSIM compatibility checker to confirm yours.
WHY GET AN ESIM FOR THAILAND?
Stacks of shops sell Thai ‘tourist’ SIMs at both Bangkok airports. But they’re not ideal.
First off, the flight from Australia to Bangkok takes around 9.5 hours, even longer on an indirect airfare. After 10 hours crammed into a tiny seat amidst an army of farting humans, do you really want to stuff around registering a SIM card?
Getting a SIM card on arrival means queuing up at a kiosk, choosing a suitable plan, surrendering your passport, paying inflated ‘airport prices,’ prying your SIM tray open, switching finger nail-sized plastic SIM cards (don’t you dare insert them upside down), and waiting for the attendant to activate your plan. Did we mention you’re jet-lagged AF?
eSIMs make things easy. You can compare prices for the best Thailand eSIMs online and install your plan in 5 minutes. With instant internet upon arrival, you can summon a fairly-priced Grab or Bolt – no more scammy airport taxis.
Secondly, airport ‘tourist’ SIMs aren’t that cheap in Thailand. I remember paying 1,000B (A$43 / $30 USD) for the cheapest 30-day AIS SIM card a few years back. That’s comparable to an eSIM, but a heck of a lot more hassle.
BKK VS DMK: THE TWO BANGKOK AIRPORTS
Bangkok has two main airports, both of which sell SIM cards.
To the east of the city centre, Suvarnabhumi (BKK) is the larger, snazzier airport and the main hub for long-haul flights. If you’re flying in from Australia on a full-service carrier like Thai Airways, Singapore Airlines, or Qantas, chances are you’ll land here.
Located in north Bangkok, Don Mueang (DMK) is an older, smaller airport serving domestic and short-haul international flights, as well as some long-haul routes operated by low-cost carriers (Air Asia, Nok Air, Thai Lion Air, etc.).
Book connecting flights with care. The two airports are 35km apart, and getting between them takes anywhere from 45 minutes to 2 hours, depending on traffic. A free shuttle service is available if needed.
WHERE TO GET A SIM CARD AT THE BANGKOK AIRPORT?
Both airports have mobile network shops within their arrival halls. Foreign cards are generally accepted, albeit with high fees and FOREX markups.
Paying in cash could save you cash. But you must first pay a hefty 250B (A$10 / $7 USD) service fee at all Thai ATMs, or visit a commission-hungry money changer (pro tip: SuperRich has reasonable FOREX rates.
The good news is that airport staff speak decent English and will help you activate your SIM.
WHERE TO GET A SIM CARD IN SUVARNABHUMI AIRPORT (BKK)?
Look for the official kiosks in the Level 2 Arrivals Hall, just outside of baggage claim. Both major Thai telcos have stores near Exits 7 and Exit 9 that operate 24 hours.
Alternatively, find the WiFi SSID "AOT Airport Free Wi-Fi by NT," and create an account to register and log in. Once connected, you can purchase and install a ZenSim travel eSIM.
WHERE TO GET A SIM CARD IN DON MUEANG AIRPORT (DMK) BANGKOK?
Likewise, you’ll find plenty of telco kiosks in the Arrival Hall of Don Mueang International Airport (DMK). There is one true dtac branch between Exit 3 and Exit 5, and another opposite Exit 6. AIS has a shopfront next to Exit 2.
To get online at DMK, the process is the same. Find the "AOT Airport Free Wi-Fi by NT" SSID and register to log on.
A TALE OF TWO THAI TELCOS
Thailand has two competing telcos: AIS and true dtac.
AIS is the premium option, with faster connections in major cities and better nationwide coverage. If you’re hopping between islands or exploring rural areas, it’s quite common to get AIS reception but not true dtac.
The cheaper telco, true dtac, used to be two separate competitors but has recently merged. The network has decent speeds within major cities but is prone to saturation during peak periods. Coverage is mostly okay outside the cities, but not as extensive as AIS.
THAI TOURIST SIM PRICES AT BANGKOK AIRPORT
Both telcos sell tourist SIMs at both Bangkok Airports.
AIS plans vary by speed. Tourist SIM plans sold at the airport cost:
- 15-day plans: From 599B (A$27 / US$20) to 1,499B (A$68 / US$49)
- 30-day plans: From 999B (A$45 / US$33) to 1,799B (A$82 / US$59)
True dtac has tourist SIMs with varying validities. At the airport, expect to pay:
- True dtac 10-day plan: 599B (A$27 / US$20)
- True dtac 30-day plan: 899B (A$41 / US$29)
You can find cheaper SIM cards at telco shopfronts and convenience stores, such as the ubiquitous 7-Eleven, in central Bangkok, or anywhere outside the airport. However, staff at these local shops speak limited or no English, making it awkward to register your plan.
COMPARING PRICES: BANGKOK AIRPORT TOURIST SIMS VS ZENSIM ESIMS
You might be surprised how little you save by getting a local SIM at the airport. Here’s what you’ll pay when getting connected the easy way with a ZenSim Thailand eSIM.
- ZenSim 10-day plans: From A$20 (US$14) to A$45 (US$32)
- ZenSim 30-day plans: From A$22 (US$16) to A$95 (US$68)
Now here’s what they look like side-by-side with Thai tourist SIMs, using AUD as the currency for comparison.
| Provider | Short-term plan (10–15 days) | 30-day plan |
|---|---|---|
| ZenSim | From A$20 to A$45 (US$14–US$32) | From A$22 to A$95 (US$16–US$68) |
| AIS | From A$27 to A$68 (US$20–US$49) | From A$45 to A$82 (US$33–US$59) |
| True dtac | A$27 (US$20) | A$41 (US$29) |
- NB: Prices and exchange rates are subject to change
All three options have varying speeds and data caps; there’s too many variables to squeeze into a tiny, mobile-friendly table.
Nonetheless, ZenSim, as you can see, is competitive on price. In certain cases, we're cheaper, while in others, we’re a smidgen more expensive.
100% of the time, however, we’re way less hassle than getting a local SIM on arrival.
