eSIM vs SIM Card Thailand: Which Is Better for Tourists?

You'll want mobile data the moment you land in Thailand, for maps, ride-hailing apps and messages home. You can pick up the tourist SIM card Thailand's mobile operators sell at airports and in shops, or buy a travel eSIM online before you fly. Both run on Thai networks, but they differ in who sells them, how long they last and whether you get a Thai phone number. Here's how each option works in 2026.

Buying a SIM card at Bangkok and Phuket airports

You can buy a Thailand tourist SIM as soon as you land. True Corporation, which runs the TrueMove H and dtac brands, sells them at official True and dtac counters in the arrivals areas of Bangkok's two airports and Phuket. Counters listed on the True-dtac website in October 2026 include:

• Suvarnabhumi (BKK): exit gates 7 and 9, and baggage-claim belts 7, 10 and 19.
• Don Mueang (DMK): near exits 3, 4 and 6.
• Phuket (HKT): baggage claim 4 after customs, and arrivals exit gates 1–2.

AIS, Thailand's other big operator, sells its own Tourist SIM and Tourist eSIM. On 5 October 2026, the True-dtac website listed the same regular prices for True's Thailand Tourist Infinite SIM and dtac's Happy Tourist Infinite SIM, as a SIM card or an eSIM: 499 THB for 8 days, 699 THB for 15 days and 1,199 THB for 30 days, or 349 THB for the 10-day data-only SIM, plus lower promotional prices. Prices change, so check the operator's site before you go.

What is the dtac Happy Tourist SIM?

Happy Tourist is dtac's prepaid range for visitors: the Happy Tourist Infinite SIM for 8, 15 or 30 days and the Happy Tourist SIM 10 Days (data only), each sold as a physical SIM card or as an eSIM at the same prices as True's. dtac and TrueMove H have shared one combined network since 2025.

A dtac eSIM changes the format, not the rules. The Happy Tourist eSIM is still a Thai prepaid line, and the True-dtac terms say tourist SIMs must be registered with a valid passport.

Passport registration and the 60-day limit

You need your passport to buy a local SIM in Thailand, and a tourist SIM lasts 60 days at most.

The SIM is registered to your passport when you buy it, and rules published by the telecoms regulator NBTC in August 2025 limit foreign nationals to three SIMs per operator. Thailand tightened SIM registration in 2025 and 2026 as part of its fight against phone scams, so expect an identity check with your passport at the counter.

Both the True-dtac terms and the NBTC rules set that 60-day cap. Topping up after expiry won't extend a tourist SIM; you have to register again with your passport in a shop.

What a travel eSIM does differently

A travel eSIM (sometimes written e-SIM) is a digital SIM you buy online before the trip and install by scanning a QR code, so there is no SIM counter to visit when you land.

• Ready before you fly. After payment, LimitSim sends the eSIM (a QR code plus manual codes) by email and to your account. Install it at home, on the phone you'll travel with; the plan details show when validity starts.
• Keep your number. Your home SIM stays in the phone for calls and texts. Switch off data roaming on it so only the eSIM uses data.
• Flexible length. Plans run from 1 to 180 days, and most can be topped up in the LimitSim app or on the website (not the 50 GB / 10 days plan).
• Thai networks. LimitSim's Thailand plans connect to AIS, dtac or TrueMove H, depending on the plan; the networks for each plan are listed on the plans page.

The trade-offs: there's no Thai phone number, and your phone must support eSIM and be carrier-unlocked. iPhones from the XS and XR onwards and Google Pixel 4 and later support eSIM; for other models, see our list of eSIM-compatible phones. Don't delete the eSIM once installed, as some can't be installed twice. Our Thailand eSIM setup guide covers iPhone and Android step by step.

eSIM vs SIM card Thailand: side-by-side comparison

The main difference is the kind of line: a travel eSIM is a data plan you buy online and install with a QR code, while a local tourist SIM or eSIM is a Thai prepaid line, registered to your passport and capped at 60 days.

eSIM or SIM card in Thailand: which should you choose?

Choose a travel eSIM if your phone supports eSIM and you'd rather not stop at a SIM counter. Choose a local tourist SIM if you need a Thai phone number or your phone can't use an eSIM.

• You need a Thai number: get a local SIM; LimitSim's plans are data only.
• Phone without eSIM: a physical Thailand SIM card is the practical option, as long as the phone is carrier-unlocked.
• Staying more than 60 days: a tourist SIM must then be registered again, while LimitSim's 50 GB / 180 days plan lasts up to 180 days. Since 15 September 2026, tourists from India, most of Europe and other countries on Thailand's list can stay up to 30 days without a visa, so check the official Thai embassy website before you travel.

FAQ

Do I need a passport to buy a SIM card in Thailand?

Yes. Local SIM cards are registered to the buyer's passport at the point of sale, so bring your original passport to the counter. Under NBTC rules from August 2025, foreign nationals can register up to three SIMs per operator.

How much does a tourist SIM card cost at Bangkok airport?

On 5 October 2026, True and dtac listed tourist SIM packages from 349 THB (10 days, data only) to 1,199 THB (30 days) on their website, plus lower promotional prices. Prices change, so check the operator's site before you travel; AIS lists its tourist packages on ais.th.

Can I buy a Thailand tourist SIM at 7-Eleven?

Yes, for some packages. True-dtac lists 7-Eleven and other convenience stores as sales points for its Infinite tourist SIMs, alongside its own shops. Take your passport, because the SIM is registered to it.

Is the dtac Happy Tourist eSIM the same as a travel eSIM?

No. The dtac Happy Tourist eSIM is a Thai prepaid line from True-dtac, registered to your passport and capped at 60 days. LimitSim's travel eSIM is a data-only plan that you buy online and install by scanning a QR code.

Can I keep my home number with a Thailand eSIM?

Yes. Your home SIM stays in the phone alongside the eSIM, so your number keeps working for calls and texts, though your home operator may charge roaming fees. Switch off data roaming on your home line so only the eSIM uses data.

Does a LimitSim eSIM come with a Thai phone number?

No. LimitSim's Thailand plans are data only, with no Thai number, calls or SMS. WhatsApp, FaceTime and other app calls work over data.
