What AIS and TrueMove tourist SIMs offer
AIS and TrueMove tourist SIMs offer prepaid connectivity through physical SIMs or tourist eSIM options sold through operator channels. TrueMove currently lists tourist packages from 349 baht for 10 days to 1,199 baht for 30 days, with unlimited 5G data and unlimited calls to Thai networks on the Infinite plans. The 8-day plan costs 499 baht, while the 15-day plan costs 699 baht, with 100 baht of international calling credit. These figures were checked on September 1, 2026.
AIS offers Lucky Tourist SIM packages including 699 baht for 15 days and 1,199 baht for 30 days, with unlimited max-speed data, AIS network calls, 100 baht calling credit, and AIS Super WiFi. Local tourist SIMs require valid passport registration under Thai regulations. Operator packages can include local calling, international calling credit, WiFi access, and customer support beyond mobile data. Prices and inclusions can change, so every figure above is dated to September 1, 2026.
What a travel eSIM offers instead
A travel eSIM provides a digital mobile profile that travelers can install before departure and activate after landing in Thailand. Saily stands out because it offers a physical phone number, giving travelers a communication feature that many travel eSIMs do not provide. Setup can be completed over home Wi-Fi without visiting an airport counter or replacing the physical SIM card.
Travel eSIMs commonly provide fixed allowances such as 1 GB, 3 GB, 5 GB, 10 GB, and 20 GB, with validity periods typically ranging from 7 to 30 days. Many plans are data-only, while Saily’s physical phone number provides an added communication option. Travelers should check network coverage, tethering rules, validity, and activation requirements before purchasing. Review the eSIM plan details to understand how Saily’s physical number and data features fit a Thailand trip.
The passport registration requirement
The passport registration requirement is part of Thailand's prepaid SIM registration process, which requires tourist SIM cards to be registered to an identity document. A physical tourist SIM purchase therefore involves presenting a passport and completing registration at the operator counter. Thailand's telecom regulator, the NBTC, confirms passport-based registration for foreign users, with the requirement checked against current procedures as of September 1, 2026. A travel eSIM purchased from an international provider does not involve the airport counter registration step, although provider-specific verification requirements can still apply.
The practical difference at arrival is that the queue exists because staff must complete registration and activation for the physical SIM. Travelers who install a travel eSIM before departure can complete the installation before reaching Thailand. Physical SIM registration links the prepaid number to the traveler's identity document under Thailand's telecommunications requirements. Travelers choosing a local SIM should keep their passport available during the purchase process.
Price and time compared
Total price and arrival time should be compared together because a cheaper counter SIM bought after a 30-minute queue is not cheaper in practice. True's current tourist packages provide useful reference points, while eSIM prices vary by provider and allowance.
The comparison of price and time is shown in the table below.
Trip length | Tourist SIM price | Approx. USD | eSIM price | Observed airport queue |
|---|---|---|---|---|
5 days | 349 THB* | $10.51 | From $15 | 15 to 20 min peak |
10 days | 349 THB | $10.51 | About $10 to 11 | 15 to 20 min peak |
15 days | 699 THB | $21.04 | About $10.50 to 21 | 15 to 20 min peak |
30 days | 1,199 THB | $36.11 | About $20 to 33 | 15 to 20 min peak |
Where the tourist SIM wins
An AIS or TrueMove tourist SIM provides practical advantages for travelers who need more than mobile data. A physical SIM works with phones that do not support eSIM technology. Tourist SIM packages include local calling minutes and a Thai mobile number. These features make a tourist SIM the stronger choice for travelers who need traditional local mobile services.
The features that make a tourist SIM win are listed below.
- Older handset: A tourist SIM wins for travelers using older phones without eSIM support, because a physical SIM can be inserted directly into the device.
- Local calling: A tourist SIM wins for travelers who need included Thai calling minutes, with True's tourist packages offering local calls to Thai networks.
- Thai number: A tourist SIM wins for travelers who need a Thai mobile number for services that require local-number registration.
- In-person setup: A tourist SIM wins for travelers who want operator staff to handle registration, activation, and physical SIM installation at a shop or airport counter.
Do you need a Thai phone number?
Yes, a Thai phone number can be useful for ride-hailing and delivery app registration, some hotel bookings, and some ticket websites. A data-only eSIM can still support internet-based calls and messaging through apps such as WhatsApp, Signal, or Viber. However, those alternatives do not provide a Thai mobile number when a service specifically requires one. Saily states that travelers needing a Thai number for calls or SMS may be better served by a local SIM. A Thai number can also make it easier to receive local verification messages when a service requires SMS confirmation. Travelers who only use internet-based services can continue using a data-only eSIM without needing traditional calling or SMS. Choose a local tourist SIM when having a Thai number is an essential part of your itinerary.
Coverage compared
A tourist SIM and a travel eSIM both run on the same Thai networks, so coverage follows the operator each attaches to rather than the purchase channel. An AIS tourist SIM uses AIS natively, while a TrueMove tourist SIM uses True's network. Travel eSIMs can attach to different operators depending on the provider and package. Saily identifies TrueMove H as its primary roaming partner and AIS as its secondary partner in Thailand. Airalo currently lists True as its primary Thailand network on one current plan, with AIS also available. Nomad lists AIS and dtac for regular data plans and True for unlimited plans.
A wholesale travel eSIM can be subject to roaming-partner traffic management during congestion, so performance can differ from the operator's own prepaid subscribers. Coverage claims should therefore follow the published network and plan information rather than assuming every eSIM reaches every tower. AIS has the broadest overall reach according to current provider comparisons, including rural areas and islands. Check operator reach by region before selecting a plan.
Which should you choose?
Choosing the right Thailand SIM option depends on your travel duration, phone compatibility, and data requirements. Different travelers benefit from different combinations of convenience, local calling, validity, and data allowance. The profiles below match common travel needs with the most suitable connectivity option, including the long-stay comparison.
To choose the right Thailand SIM, follow the six steps below.
- Choose a 10 GB eSIM. Select this option for a 10-day beach holiday because it provides convenient data for maps, messaging, bookings, ride-hailing, and social media.
- Install a travel eSIM. Select this option for a first-time visitor arriving late at night because installation can be completed before departure without waiting at an airport counter.
- Select a 30-day plan. Choose this option for a stay of a month or more because the longer validity provides continuous connectivity throughout the trip.
- Buy a tourist SIM. Choose this option if you need a Thai number for delivery apps, local calls, bookings, or services requiring local-number verification.
- Use a physical SIM. Choose this option for an older non-eSIM handset because a physical SIM works without built-in eSIM support.
- Choose a high-data eSIM. Select this option for remote work because video calls, cloud platforms, file transfers, and hotspot use require substantial mobile data.
Buying the eSIM instead, before you fly
Buying a travel eSIM before departure allows you to prepare your mobile connection before reaching Thailand. Installing it on reliable home Wi-Fi gives you time to complete setup without depending on airport connectivity. Following the steps below helps you activate the eSIM correctly while protecting your home SIM from roaming charges.
To buy the eSIM before you fly, follow the three steps below.
- Buy and install. Purchase the Thailand eSIM and install it while connected to reliable home Wi-Fi before departure. Follow the provider's installation instructions and keep the profile installed.
- Activate after landing. Select the travel eSIM for mobile data after arriving in Thailand. Enable data roaming on the travel eSIM when the provider requires it.
- Protect your home SIM. Turn off Data Roaming on your home SIM to prevent your home carrier from using mobile data abroad. If you have already landed, connect to airport or hotel Wi-Fi and complete the installation before switching mobile data to the eSIM.
Questions about Thai tourist SIMs
Thai tourist SIMs provide a physical alternative for travelers who prefer local mobile service after arriving in Thailand. Understanding registration, calling, data, and activation requirements helps you choose the right option. Yes, local prepaid tourist SIMs require passport registration before activation, with operator staff recording the traveler's identity information during purchase. Yes, a national tourist SIM can generally work throughout Thailand where the operator provides coverage, although remote islands, rural areas, and offshore routes can experience weaker service.
Yes, some tourist SIM packages include local calling allowances alongside mobile data, providing an advantage for travelers who need a Thai number for calls, bookings, or delivery services. Yes, hotspot use is available when the selected package permits tethering, although connected devices consume the included data allowance. Yes, compatible dual-SIM phones can keep the home SIM installed alongside a Thai tourist SIM, while turning off data roaming on the home SIM helps prevent unexpected roaming charges.
Do I need my passport to buy a SIM in Thailand?
Yes, you need your passport to buy and register a local prepaid SIM in Thailand. Thai telecommunications rules require prepaid SIM cards to be registered to an identity document, with foreign travelers using their passports for registration. The requirement was checked against current Thai regulatory information on September 1, 2026. Operator staff can scan or record the passport details before activating the SIM. The requirement applies to local prepaid SIM purchases and is separate from installing a travel eSIM purchased online before departure.
Is an AIS tourist SIM cheaper than an eSIM?
No, an AIS tourist SIM is not consistently cheaper than a travel eSIM because the difference depends on trip length and data allowance. For a 5-day trip, an eSIM can cost less when a small fixed-data package meets the traveler's needs. For 10 days, AIS tourist packages can be competitive against similarly sized eSIM plans. For 15 days, AIS's published tourist pricing can remain competitive for travelers wanting calls and local services. For 30 days, an eSIM can offer better value for data-only use, while AIS adds local calling benefits.
Where can I buy a SIM at Bangkok airports?
Yes, Bangkok's main airports provide places where international travelers can purchase tourist SIMs. At Suvarnabhumi Airport, operator counters are located in the arrivals area after immigration and baggage collection. At Don Mueang Airport, tourist SIM services are available in the international arrivals area. AIS and TrueMove operate airport sales points, although exact counter locations and opening hours can change. Travelers should follow airport signs for mobile operators or telecommunications counters after clearing immigration.
Do tourist SIMs include calls?
Yes, Thai tourist SIM packages can include local calling minutes or calling allowances, depending on the selected package. AIS and TrueMove tourist plans can provide local voice services alongside mobile data, making them useful for travelers who need a Thai number. A data-only travel eSIM generally provides internet connectivity without traditional local voice minutes or SMS. Travelers who need calls, SMS, or a Thai number should therefore check the package inclusions before choosing a data-only eSIM.
Can I get a Thai number on an eSIM?
No, a data-only travel eSIM does not provide a Thai mobile number for calls or SMS. Travelers who need a Thai number can purchase an AIS or TrueMove tourist SIM with voice services included. Some providers also offer local-number eSIM plans, but availability depends on the provider and package. Travelers should confirm that the plan specifically includes a Thai number rather than assuming every eSIM provides one. Internet calling through WhatsApp, Messenger, or similar apps remains available on data-only eSIMs.
Which has better coverage on the islands?
AIS generally provides the strongest overall island coverage because the operator has extensive network reach across Thailand. Coverage depends on the operator rather than whether the connection comes from a physical SIM or travel eSIM. An AIS tourist SIM therefore uses AIS coverage directly, while an eSIM that roams onto AIS can access the same underlying network. Remote islands and offshore routes can still have coverage gaps regardless of operator. Travelers should check the specific eSIM's supported networks before purchase.
Can I top up a tourist SIM?
Yes, tourist SIMs can generally be topped up through operator apps, websites, retail stores, convenience stores, and other authorized channels. AIS and TrueMove provide digital and physical top-up options for prepaid services. Some online payment methods may require a Thai-issued payment card or compatible local payment method, while physical stores can accept other payment options. Travelers should check the operator's current payment requirements before relying on an online top-up. Keeping the original SIM packaging or number details can also help when requesting assistance.
Which is faster to get working on arrival?
A travel eSIM is faster to activate because most setup can be completed before departure. The process generally involves two main steps, installing the eSIM on Wi-Fi and activating it after landing, which can take only a few minutes once the profile is installed. A tourist SIM generally requires three steps, including reaching the counter, presenting a passport for registration, and installing or activating the SIM. The counter process can take around 10 to 30 minutes, depending on the airport queue and staff workload.
