Don Mueang SIM Card Guide: Prices, Operators & What to Skip (2026)
✅ Last verified on-the-ground: 2026-07-17
You land at Don Mueang (DMK) and your phone has no data. Before food, before a bed, before the exchange counter, you need a Thailand SIM card. Don Mueang airport has three official operator counters in arrivals. This guide tells you exactly which one to walk up to, what to pay, what to skip, and what to do instead if your phone supports eSIM.
Quick Answers
| What | Answer | Price (INR) |
|---|---|---|
| Cheapest tourist SIM at Don Mueang | AIS Traveller SIM 15-day, 15 GB | ₹1,145 (~399 THB) |
| Best coverage across Thailand | DTAC (True/DTAC merged network post-2023) | ₹858-₹1,719 (~299-599 THB) |

What’s at Don Mueang (Terminal 1, International Arrivals)
Don Mueang is the older of Bangkok’s two airports and the main hub for AirAsia, Nok Air, Thai Lion Air, and most Indian carrier arrivals (IndiGo, SpiceJet, Thai AirAsia flights from Kolkata, Chennai, Hyderabad). When you walk out of the immigration hall and into the public arrivals concourse, you will see three operator counters in a row, plus a generic “SIM card” kiosk run by a third party.
The three main operator counters are:
- AIS (purple branding) - Thailand’s largest operator by subscriber base.
- DTAC (blue branding, now rebranded under True/DTAC post-merger).
- TrueMove H (red branding, the consumer arm of True Corporation).
AIS and TrueMove counters at Don Mueang typically open from around 6 AM until the last international arrival. For late-night landings, AIS usually keeps a 24-hour booth near Gate 5; DTAC and TrueMove counters have shorter hours, so if you land after midnight, AIS is your safest bet.
Subodh’s Pro Tip: Counters near the baggage belt (before immigration) tend to be staffed by airport contractors, not by the operators directly. Walk past them, clear immigration, and buy your SIM from the official operator counter after you exit. The price is the same, but the official counter will register the SIM to your passport, which means it will work properly across Thailand instead of dying in three days.
Operator Comparison at Don Mueang
AIS Traveller SIM
AIS is the default choice for most Indian backpackers and the counter most often recommended by Don Mueang staff. Their standard tourist SIM at the airport is the Traveller 15-day plan: 15 GB of 4G/5G data, 100 minutes of domestic calls, free incoming calls, and free data roaming in selected ASEAN countries if you extend your trip to Laos, Cambodia, or Vietnam.
The plan is priced at ₹1,145 (~399 THB or ~$11.88) at the airport counter, the same as their official 7-Eleven retail price, so there is no airport markup on the headline number. Activation is straightforward: hand over your passport, the staff scans it, you wait three minutes, and the SIM is live. The catch is the 5G coverage: in central Bangkok (Sukhumvit, Silom, Khao San) you will get 5G, but the moment you leave the city for Pai, Koh Tao, or any northern mountain town, you fall back to 4G or even 3G.
DTAC (True/DTAC Network)
DTAC’s tourist offering at Don Mueang is rebranded under the True umbrella but the SIM and the plans still carry the DTAC brand. The headline tourist SIM at the counter is the ₹858 (~299 THB or ~$8.91) 8-day plan or the ₹1,719 (~599 THB or ~$17.84) 15-day plan with 25 GB. The ₹1,719 (~599 THB or ~$17.84) plan is the better value if you need more data, but the ₹858 (~299 THB or ~$8.91) plan at Don Mueang often carries an airport-only surcharge, so it ends up at ₹1,004 (~350 THB or ~$10.42).
DTAC’s network is slightly weaker than AIS in rural Thailand but equivalent in Bangkok and Chiang Mai. The real reason some travellers prefer DTAC is customer service: their app and hotline have historically had English-language support that is more responsive than AIS, which matters if you have a SIM registration issue.
TrueMove H
TrueMove’s tourist SIM at Don Mueang is the cheapest of the three operators, with a basic 8-day 5 GB plan at ₹284 (~99 THB or ~$2.95). The cheap price comes with tradeoffs: TrueMove’s 4G speeds are noticeably slower than AIS or DTAC in the same area, and the smaller data cap burns through fast if you are using Google Maps, Uber, and WhatsApp calls daily.
For a three-night stopover in Bangkok before flying onward, TrueMove’s ₹284 (~99 THB) plan is fine. For any trip longer than five days, pay the extra for an AIS Traveller SIM.
What to Skip: Third-Party SIM Kiosks
The biggest rip-off at Don Mueang is not any of the three operator counters. It is the third-party “Tourist SIM with free hotel transfer” kiosk that operates in the baggage-hall area before immigration. They sell SIM cards bundled with a “free” taxi voucher or “free” hotel transfer, and the SIM itself is often a cheap TrueMove basic SIM marked up to ₹2,295-₹4,304 (~800-1,500 THB). The transfer is rarely free: it is a shared minibus that drops you at a specific hotel zone and tries to upsell you a tour.
Travellers report being told a “special price” that is actually the standard retail rate. Walk past, clear immigration, and buy from the official counter.
Safety Alert: Do not hand your passport to any third-party SIM tout, even if they offer a “VIP fast-track immigration” bundle. Only AIS, DTAC, or TrueMove staff at the official operator counters are authorised to register prepaid SIMs to your passport. Unofficial registrations can be flagged at Thai immigration checkpoints and may cause issues when you try to extend your visa or cross into Laos or Cambodia.
The eSIM Alternative
If your phone supports eSIM (most phones bought in India after 2022 do: iPhone XR and later, Samsung Galaxy S20 and later, Pixel 4 and later, OnePlus 7 and later), skip the airport SIM entirely and buy a regional eSIM before you fly. Nomad eSIM’s Thailand plan starts at around ₹482 (~5 USD) for 5 GB over 7 days, activates the moment your flight lands, and works in parallel with your Indian SIM so you can keep WhatsApp receiving on your regular number.
The eSIM activation flow: buy online, receive a QR code by email, scan it in your phone’s cellular settings while still on airport Wi-Fi at your departure gate, and the eSIM profile is installed before you take off. By the time you land at Don Mueang, you have data without setting foot in the terminal.
The catch is data caps and cost-per-GB. Nomad and Airalo’s Thailand eSIMs are roughly 4-6x more expensive per GB than a ₹1,145 (~399 THB or ~$11.88) AIS Traveller SIM. For a two-week trip with daily Google Maps, Uber, Instagram, and WhatsApp, an eSIM gets expensive fast.

Setup at the Counter: What to Have Ready
When you walk up to the AIS, DTAC, or TrueMove counter, you need three things:
- Passport (not a photocopy, not a photo on your phone).
- Cash (₹1,148-₹1,721 (~$11.92-$17.87), ~₹1,148-₹1,721 (~400-600 THB or ~$11.91-$17.87)). The operator counters at Don Mueang accept Thai baht cash, and most accept Visa/Mastercard. Some smaller kiosks are cash-only.
- Phone with the SIM tray unlocked (i.e. Not carrier-locked to Jio, Airtel, or Vi). Indian phones sold since 2020 are mostly unlocked, but check your settings before you fly.
Activation takes 3-5 minutes. The staff will:
- Scan your passport.
- Take your photo for their system (legal requirement under Thai SIM registration law).
- Slot the SIM into your phone (hand it to you if you prefer to do it yourself).
- Run a speed test to confirm data is working.
- Set up your APN automatically.
Subodh’s Pro Tip: Ask the counter staff to write down your new Thai mobile number on the back of your SIM card holder or on a small piece of paper. You will need it for: Grab registration, OTPs from Thai banks and SIM vendors, WhatsApp verification if you change phones later, and emergency contacts with other travellers.
After the Airport: Topping Up and Recharging
Once you leave Don Mueang, topping up your SIM is easy. AIS, DTAC, and TrueMove all sell top-up cards at 7-Eleven, which is on every second block in Bangkok. The standard top-up denominations are 50, 100, 200, 500, and ₹2,869 (~1,000 THB or ~$29.78). You scratch the card, enter the code, and the credit loads immediately.
For data packs (separate from voice credit), use the operator’s app:
- AIS: My AIS app (English available).
- DTAC: DTAC app.
- TrueMove: TrueMove H app.
All three apps accept Thai debit/credit cards and international Visa/Mastercard. If you have a forex card like Niyo or Fi, it works at the app-level top-up.
Common Questions Indians Ask at the Don Mueang Counter
“Will my Airtel / Jio number work in Thailand without a SIM?” Yes, but at international roaming rates (around ₹500-700/day for 1 GB packs from Airtel). It is the most expensive option. For a two-week trip, roaming costs 10-15x what a local ₹1,145 (~399 THB or ~$11.88) SIM costs. See our Airtel international roaming Thailand review for the full breakdown.
“Can I keep my Indian number active for OTPs?” Yes. Dual-SIM phones (almost every phone sold in India) run both your Indian SIM and your Thai SIM at the same time. Set the Thai SIM as your data line and your Indian SIM for calls and SMS. OTPs from Indian banks, IRCTC, and UPI apps arrive on your Indian number without issue.
“Do I need to register my Thai SIM online?” No. The passport scan at the counter is the registration. Thai law requires all prepaid SIMs to be tied to a passport, and the counter handles that automatically. You do not need to do anything else.
“What if I land after midnight and the counters are closed?” AIS usually has a 24-hour booth near international Gate 5. If it is also closed, head to the official AIS shop outside the airport (5-minute taxi ride, around ₹287 (~100 THB or ~$2.98)) or buy a TrueMove SIM from any 7-Eleven the next morning. Avoid the third-party late-night touts near the taxi stand.
“Can I use the same SIM in Cambodia, Laos, and Vietnam?” The AIS Traveller SIM includes free data roaming in selected ASEAN countries (the list rotates, but Cambodia, Laos, and Vietnam are usually included). Speeds are throttled to 128 kbps, which is enough for WhatsApp and Maps but not for video calls. For serious data in those countries, buy a local SIM when you cross the border.
Where to Eat Near Don Mueang (While Your SIM Activates)
While waiting for your SIM to register, the arrivals concourse has limited but functional food. For something better, take a 15-minute taxi into central Bangkok. Some honest picks from our Bangkok shortlist:
- Amritsr Restaurant Sukhumvit Soi 22 (rating 4.8): North Indian with stuffed parathas at ₹2,869-₹5,738 (~1,000-2,000 THB or ~$29.78-$59.57) per person. The dal-chawal fix after a 4 AM landing.
- Aonchorn Thai restaurant ออนชอน ราชดำเนิน (rating 4.9): Local Thai with authentic flavours. Order the boat noodles and pad see ew.
- Indique (rating 4.9): Indian fine dining option, the butter chicken is the move.
- Shree Gangour Pure Veg Restaurant Bangkok (rating 4.9): Strict-veg Indian option in Bangkok.

Don Mueang vs Suvarnabhumi: Quick Note
If you are arriving at Suvarnabhumi (BKK) instead, the same three operators run identical counters in that airport, and the prices are the same (₹1,145 (~399 THB or ~$11.88) for AIS, ₹858-₹1,719 (~299-599 THB or ~$8.91-$17.84) for DTAC, ₹284 (~99 THB or ~$2.95) for TrueMove). The only real difference is BKK has a wider range of eSIM kiosks inside the terminal and a slightly better late-night staffing. For a full Suvarnabhumi-specific breakdown, see our Bangkok arrival guide.
FAQ
Is ₹1,145 (~399 THB or ~$11.88) the cheapest I will find for a 15-day SIM? No. If you buy in central Bangkok at any AIS shop (not the 7-Eleven reseller counters), the same plan is ₹1,001 (~349 THB or ~$10.39). The airport premium on a 15-day plan is small. On shorter plans (3-5 days), the airport markup is more aggressive.
Do I need a 5G SIM? No. 4G is fine for Grab, Google Maps, WhatsApp, and Instagram. 5G matters only for hotspot tethering to a laptop or streaming video on the go. If you are not doing either, save the extra ₹287 (~100 THB or ~$2.98).
Can I get my SIM card replaced if I lose it? Yes, any AIS, DTAC, or TrueMove shop in Thailand can issue a replacement with your passport. There is a small fee (₹143-₹287 (~50-100 THB or ~$1.49-$2.98)) and your number and remaining balance transfer over.
Will my Thai SIM work in Laos or Cambodia? Yes, but with limits. AIS includes ASEAN roaming at throttled speeds. DTAC and TrueMove charge per-day rates. For heavy data use across borders, buy a local SIM when you arrive.
Should I buy a SIM before flying from India? No. Prepaid tourist SIMs sold on Indian e-commerce sites (Amazon India, Flipkart) are 2-3x the airport price for the same plan, and they often do not include Thailand-issued numbers.
Subodh’s Take
Here is the honest call: buy the AIS Traveller SIM at the airport counter for ₹1,145 (~399 THB or ~$11.88), walk past every third-party “free transfer” tout, and you are done. DTAC and TrueMove are fine alternatives but AIS has the strongest rural coverage, which matters once you leave Bangkok for Pai, Koh Tao, or the northern loop. If your phone supports eSIM and you only need data for under a week, the eSIM saves you the airport counter visit entirely. Anything beyond that, the AIS SIM is the move.
