Best eSIM for 🇹🇭 Thailand: 7 Providers and Local Tourist Plans

The best eSIM for Thailand depends on whether you need mobile data, a Thai phone number or enough hotspot data for a laptop. Those are different purchases: a cheap roaming package can handle maps and messaging, while a local tourist eSIM may include calls and require passport registration.

For a Bangkok–Chiang Mai trip or a week around Phuket and Krabi, compare the full package price and expiry first. This guide covers seven travel eSIM providers, local AIS and dtac alternatives, and the installation rules that can start your plan earlier than expected.

Quick Verdict: Which Thailand eSIM Should You Choose?

  • For 10GB across a two-week trip: Nomad eSIM. Its regular 10GB/30-day package costs US$10 and lists AIS and dtac. Our eligible first-purchase code reduces that to a calculated US$8.50.
  • For 5GB over one week: Airalo or Jetpac. Both cost US$7; Airalo lasts seven days, while Jetpac lasts 30.
  • For an existing Saily user: 10GB/30 days costs US$10.99 before our 10% reader discount, and you can add the plan to your existing Saily eSIM.
  • For a Thai number and local calls: compare AIS and dtac tourist eSIMs separately. A travel provider’s app-based calling feature is not necessarily a Thai mobile number.
  • For heavy use: choose by the high-speed allowance and hotspot rules. Holafly’s Thailand plan allows only 1GB of hotspot data per day.

Thailand eSIM Prices for 7- and 14-Day Trips

We use two shopping scenarios: at least 5GB for seven days and at least 10GB for 14 days. The table compares suitable prepaid purchases, not a prorated daily price. These allowances are examples for planning, not a claim that everyone uses the same amount.

USD package prices checked October 6, 2026, before discount codes. Each cell is a complete purchase with its actual allowance and validity. Ubigi supplies 10GB in the one-week basket; Holafly’s different allowance model appears in the next table.

Nomad has the lowest standard price for the two-week 10GB scenario among these six fixed-data options. For the smaller week-long basket, Airalo and Jetpac tie on price, but Jetpac leaves more time to use the allowance. If you expect to need 10GB within seven days, Ubigi’s US$9 one-off package is worth the small increase over a 5GB plan.

This is a comparison of published packages and provider documentation, not an on-the-ground speed test. We do not assign a universal coverage winner. Local tourist products are listed separately in their advertised currency because they include different services.

Unlimited Thailand eSIMs: What Happens After the Fast Data?

A daily allowance suits steady use. A trip-wide allowance lets you spend more data on a few busy days. Neither makes laptop updates or large cloud backups free of limits.

USD prices checked October 6, 2026, before codes. Longer packages are charged in full. Daily allowances, trip-wide allowances and unspecified fair-use policies are different products, even when all are called unlimited.

For uneven usage, Ubigi’s trip-wide allowance is useful: its 15-day plan provides 30GB before the 2 Mbps restriction, so a large upload does not consume a small daily quota. For regular phone use, Saily and Airalo offer a larger daily high-speed allowance than the listed Jetpac and aloSIM plans.

Hotspot is a separate question. Holafly limits sharing to 1GB per day, even though phone data is sold as unlimited. Saily permits hotspot, but its consumer-use terms restrict sustained heavy tethering and commercial redistribution. Do not treat a phone plan as a guaranteed replacement for a work connection.

Nomad’s local unlimited packages have different activation and calling conditions from its ordinary fixed-data plans. Their linked documentation does not clearly establish a numeric full-speed allowance for these products, so the low price alone does not make them our first choice for demanding use.

AIS and dtac: When a Local Tourist eSIM Makes More Sense

Consider a local tourist eSIM when you want a Thai number, ordinary local calls or help from an operator shop. The eSIM format does not remove registration: prepare your passport and complete the seller’s identity checks.

Official operator-listed prices checked October 6, 2026. Prices remain in THB; they are not converted USD checkout quotes. Select eSIM rather than a physical SIM. Registration and the exact product’s calling and fair-use terms apply.

AIS Lucky Tourist includes calls within AIS and THB100 credit for other Thai networks and eligible international calls via its specified dialling service. That is different from unlimited calls to every network. See the AIS tourist-plan benefits and registration guidance.

dtac Happy Tourist advertises calls within dtac and THB15 credit. The separate Infinite range advertises calls to all Thai networks. Do not confuse a 15GB or 30GB high-speed allowance with the Infinite product just because both use the word unlimited. The operator’s product breakdown distinguishes them.

These local packages are useful alternatives, but their public summaries do not establish a simple, universal hotspot allowance. If sharing several gigabytes daily is essential, get the exact plan’s tethering conditions from the operator before choosing it for that purpose. True/dtac also publishes registration and service-use terms.

Thai Networks, Islands and Hotspot: What to Check

The travel eSIM brand sells the package; a Thai network carries the connection. Knowing the network is useful when checking a hotel, island or onward route, but it is not enough to predict performance inside a particular building.

Network disclosures checked October 6, 2026. These apply to the named Thailand products, not automatically to regional packages. A listed network or 5G label does not guarantee signal or speed at every stop.

For Bangkok, Chiang Mai, Phuket and Krabi, start with price, allowance and the networks available to your exact plan. For a smaller island, a national park or a long ferry crossing, save maps and tickets offline and ask your accommodation which network works at its location. Do not infer continuous coverage between destinations from coverage in the towns themselves.

Southern-route exception: the selected Nomad 10GB package states that service is unavailable in Pattani, Narathiwat and Yala, and in Chana, Na Thawi, Thepha and Saba Yoi districts. If your route includes those places, resolve availability for the exact product before buying; a nationwide marketing description is not sufficient.

The 5GB and 10GB packages start on the first successful destination data connection, with an automatic start after 60 days if unused. Add-ons are available while the plan is still active. Follow the instructions for your exact package: Nomad’s 50GB and local unlimited options have different activation rules.

Check your southern route. The selected 10GB plan states that service is unavailable in Pattani, Narathiwat and Yala, and in Chana, Na Thawi, Thepha and Saba Yoi. Do not treat the listed AIS and dtac networks as a guarantee of service at every stop.

The 50GB/10-day package at US$12 is a different choice. It does not cover a two-week trip or qualify for our discount. Its specific plan instructions say to install it only after arriving in Thailand and state no local number, no add-on and no refund.

The separate 30-day local unlimited plan includes a Thai number and local calls. It also starts on installation, so install it only after arrival. Nomad requires a visit to a True shop to verify identity and enable outgoing calls. Do not assume these benefits apply to the 5GB, 10GB, 50GB or 10-day unlimited packages.

The Maew packages checked here start on first use in Thailand and do not require identity verification. Top-ups are supported, but each purchased package has its own expiry even when the eSIM profile remains reusable. These are data-only plans, rather than the older dtac tourist packages with local calling benefits.

Airalo’s hotspot guidance allows tethering when your device and network support it. Sharing a connection uses the same data allowance.

Need more data? Separate Maew unlimited options list 5GB of high-speed data per day, followed by a reduced speed of 1Mbps. That daily limit applies to those unlimited packages, not to the fixed-data plans in the table.

Enable the installed Saily eSIM and data roaming when you arrive. An unused purchase starts automatically after its 180-day activation window. The public Thailand page does not name a local partner, so we cannot recommend these packages specifically for AIS, True or dtac access. Saily’s separate phone-number add-on provides a US number, not a Thai mobile number.

The separate Thailand unlimited plan offers 5GB of high-speed data per day, then up to 1 Mbps. Its allowance resets at local midnight. Saily’s unlimited-plan fair-use terms restrict continuous heavy use and excessive tethering, so it is not a replacement for a fixed internet connection.

MYTECHGUIDE

Enter MYTECHGUIDE for 10% off your first Ubigi purchase. Valid for all destinations on one-off and annual data plans only. Monthly subscriptions are excluded.

Install the eSIM before travelling. SmartStart begins the package when you arrive in a destination it covers; an unused plan expires if it is not activated within six months of purchase. Keep the eSIM profile for later trips and top-ups. Ubigi also supports in-app top-ups without Wi-Fi or remaining data credits.

Choose the right billing model. The separate 5GB monthly subscription costs US$6 per month and permits cancellation only after three months. That means a minimum US$18 commitment, with the allowance renewing monthly. For a single holiday, compare the one-off packages above.

For larger, uneven data use: the separate 15-day unlimited plan’s fair-use policy gives you 30GB at full speed, then 2Mbps for the rest of the package. Its high-speed allowance is shared across the whole validity period rather than resetting daily, which can suit occasional larger uploads.

Consider another option if…

You need a Thai mobile number, the lowest price for 10GB, or a larger disclosed daily fast-data allowance on an unlimited plan.

A limited fallback when your main data runs out. Qualifying packs of 3GB or more advertise continued access to WhatsApp chat, Uber, Grab and Google Maps navigation. This covers the named functions, not unrestricted browsing, streaming or video calls.

Keep fixed data and unlimited separate. Jetpac’s unlimited Thailand product allows 3GB at standard network speeds per 24-hour cycle, then up to 1 Mbps until the next cycle. The table above lists fixed-data packages. You can install before departure, then turn on the Jetpac line and its data roaming after arriving in Thailand.

The calling bonus works through another app. The Hushed promotion supplies a US or Canadian number with US$3 of calling and texting credit on qualifying packages. Redeem it after purchase and use Hushed over data or Wi-Fi. It does not add a Thai mobile number to the eSIM; if a service requires one, choose a local tourist SIM instead.

Unlimited does not guarantee full speed throughout the day. Holafly’s fair-use explanation allows temporary speed reductions by the local operator. A numeric full-speed phone-data allowance is not disclosed for the Thailand product, so it cannot be compared like-for-like with a plan promising a specific daily high-speed amount.

Install before you travel; activate in Thailand. Set up the eSIM while you have a reliable internet connection. The package starts when it connects to a supported network at your destination. Use internet calling apps for calls; this data-only product does not include a Thai number.

Continuing to Laos, Cambodia, Malaysia or Singapore?

A Thailand-only plan stops being useful when you leave its coverage area, even if data remains. Choose a regional product only after matching its country list to every stop. Our Southeast Asia eSIM comparison covers the wider route decision.

Nomad APAC has two materially different versions. The checked 14-destination version includes Thailand, Malaysia and Singapore but excludes Laos and Cambodia. The 21-destination version includes Thailand, Laos and Cambodia but excludes Singapore. More destinations does not mean that every country from the smaller package is retained.

For country-specific alternatives, see our guides to Laos eSIMs, Cambodia eSIMs and Malaysia eSIMs. Keep each package’s network and activation rules separate; a Thailand local plan does not establish how the regional plan behaves.

How Much Data Do You Need, and When Should You Install?

Start with 5GB for a week if most video and large downloads happen on Wi-Fi; consider 10GB for two weeks of regular travel use. Treat these as starting budgets. Photo uploads, video calls and laptop updates can change the total quickly; use our travel data guide to build your own estimate.

  1. Check the exact phone model and carrier lock. Follow our eSIM compatibility guide before paying.
  2. Read the activation event for the purchased product. Many travel packages can be installed before departure. Nomad’s Thailand 50GB and local unlimited options are important exceptions: their instructions say to install only after arrival.
  3. Keep installation details available. Use a reliable Wi-Fi connection. For a product that must be installed in Thailand, plan access to airport or accommodation Wi-Fi.
  4. Choose the travel eSIM for mobile data. Enable data roaming on it when instructed. Disable home-line data roaming and automatic mobile-data switching to avoid unintended home-carrier data use.
  5. Check the first connection, expiry and balance. Complete any required registration before relying on local calls. Do not delete the eSIM as an initial troubleshooting step; reinstallation may be restricted.

You can often keep your regular SIM active alongside the travel eSIM. Our dual-SIM guide explains the setup. Calls and texts on the home line still follow your home operator’s roaming terms.

Final Verdict

Start with Nomad’s regular fixed-data plan for a two-week trip needing around 10GB. It offers a low purchase price, extra validity and named networks. For a smaller 5GB week, Airalo and Jetpac cost less; Jetpac gives the allowance a longer lifespan.

Stay with Saily if its existing setup and reader discount suit you. Consider Ubigi for a data-heavy week or a trip-wide unlimited allowance. For a Thai number, compare local tourist products and complete registration. For unlimited phone use, check the daily cap and hotspot allowance before paying a premium.

Browse our eSIM guides by destination when planning your next stop.

FAQ

Is an eSIM cheaper than buying a tourist SIM at the airport?

It can be for a small data-only allowance, but the products may include different services. Compare the full package you need, including validity, local calls and registration. An airport tourist SIM is not automatically a worse deal because it is sold in person.

Which Thailand eSIM includes a Thai phone number?

Local AIS and dtac tourist products are the main options discussed here. Nomad’s 30-day local unlimited product also includes a number, with identity verification needed to enable outgoing calls. The ordinary fixed-data plans in our first table do not include a native Thai number; separate app-based calling offers are different.

Do I need a passport to buy a Thailand eSIM?

Local tourist SIMs require registration, including passport identification for foreign visitors. Requirements for international travel-data products vary: the checked Airalo Maew and aloSIM Thailand products state no identity verification requirement. Follow the instructions for the exact eSIM you buy.

Will a Thailand eSIM work on Phuket, Koh Samui and other islands?

The included network matters more than the eSIM format. Coverage in populated tourist areas does not guarantee service on every beach, inside every hotel or during a boat crossing. Check your specific accommodation and route, and keep essential information offline.

Can I install every Thailand eSIM before departure?

No. Installation is separate from activation for many products, but some local packages start their validity immediately when installed. Follow the product-specific rule, especially for Nomad’s Thailand 50GB and local unlimited options.

Does unlimited data mean unlimited hotspot?

No. A plan may limit sharing separately or slow down after a daily or trip-wide allowance. Holafly’s Thailand product, for example, limits hotspot to 1GB per day. A plan with a clear usable allowance is a better starting point than the unlimited label alone.

Stay connected. Spend less.
