Thailand welcomed over 35 million international tourists in 2024, and in 2025, it’s one of the easiest countries in Asia to stay connected.

An eSIM gives you local or regional mobile data without needing a physical SIM card. Everything’s digital — just download the app, activate your plan, and go. It’s perfect for using maps, booking rides, posting on Instagram, or staying in touch with family through WhatsApp.

If you’re planning a trip to Thailand, staying connected is easy — and it doesn’t have to be expensive or complicated. Thanks to eSIM technology, travelers can now access reliable mobile data without needing to hunt down a local store or swap physical SIM cards.
Thailand is well-served by a number of top eSIM providers, each offering different strengths based on how much data you use, how long you’re staying, and how hands-off you want the experience to be. Here's a breakdown of the 6 best eSIM options for Thailand in 2025.
Saily, from the creators of NordVPN, is a newer eSIM provider offering simple, secure, and low-cost plans. It’s best for light users who want quick access without overpaying. Prices start around $4.99 for 1GB, and setup is quick through their app.
Saily focuses on reliability and privacy, with a clean interface and good speeds. It’s a solid option if you want to save money, don’t use much data, or just want a backup connection for when Wi-Fi isn’t available.
Holafly is a go-to option for travelers who want unlimited data and zero stress. It’s popular with digital nomads, streamers, or anyone who doesn’t want to think about running out of data. Their eSIM for Thailand offers unlimited usage starting at around $6 per day, making it ideal if you plan to stay online throughout your trip.
Setup is fast, customer support is solid, and you’ll be connected in minutes after installation. Holafly doesn’t include a Thai phone number or SMS capabilities, but for most visitors using apps like WhatsApp or Line, that’s not an issue. If you're happy to pay a bit more for a seamless experience and unlimited data, Holafly is a strong choice.
If you're more budget-focused and don’t need unlimited data, Airalo is a great option. It’s the largest eSIM marketplace globally, trusted by millions, and known for its affordable pricing and flexibility.
For Thailand, Airalo offers plans starting at $4.50 for 1GB, with larger packages up to 20GB valid for 30 days. It’s perfect for shorter trips or travelers who mostly use hotel Wi-Fi but still want mobile access for maps, messaging, and bookings. Plans are data-only, so there's no Thai number, and you’ll need to top up once you hit your limit — but the app makes this easy to manage.
SimOptions is a global eSIM marketplace offering a wide range of prepaid data plans for Thailand — from light use to unlimited data. What sets SimOptions apart is that they don’t just offer data-only plans — they also partner with Thai providers like dtac to provide tourist-ready eSIMs that include calls, SMS, and a local Thai number.
Their top option for travelers is the dtac Happy Tourist eSIM, which includes unlimited data, local calls, and SMS, available in 10, 15, or 30-day packages, starting at $9.90. This makes SimOptions one of the few providers offering full mobile functionality beyond just internet.
Nomad strikes a nice balance between cost and performance. It's not as well-known as Holafly or Airalo but offers good value mid-range plans, like 10GB for around $18 USD, valid for 30 days.
Nomad eSIMs run on the AIS network — one of Thailand’s biggest and fastest — so coverage is reliable, even in smaller cities and islands. Their app is clean and easy to use, though support can be slower than top-tier competitors. Nomad is a good pick if you don’t need unlimited data but want enough for navigation, social media, and streaming without constantly topping up.
Jetpac is a newer name, but quickly gaining attention for offering a lot of data at very low prices. Their standout Thailand offer is 50GB for just $10, valid for 10 days — perfect for heavy data users on shorter trips.
Jetpac also partners with AIS, so speeds and coverage are solid across most of the country. The app is basic, and the eSIM is data-only (no phone number), but at under $0.25 per GB, it’s hard to beat for value. It’s ideal for people who stream, upload content, or just want to stay online without worrying about limits.
If you're staying in Thailand for more than a few days or want a local number with calling options, you can also get an eSIM directly from Thai mobile operators. While most of these plans require in-person activation, they can be a good option if you want a more traditional local experience with voice, SMS, and data included.
Here’s what to expect from the two major carriers currently offering eSIMs to prepaid customers: AIS and DTAC.
AIS is one of Thailand’s largest and most established telecom providers. They offer eSIM support for prepaid users, but only after you've purchased a physical prepaid SIM card first. Once activated, you can convert it into a virtual SIM at no extra cost.
AIS prepaid plans range from $11.50 to $49, depending on the duration and data allowance. These eSIMs work on phones, tablets, and other compatible devices, and you can check compatibility on their website.
Benefits of AIS eSIM:
How to activate: Visit any AIS store, buy a prepaid SIM card, and request to convert it to eSIM. You’ll need to show your passport and have a compatible device. Staff will register the SIM and help with setup on the spot.
Dtac’s Happy Tourist Infinite SIM is one of the most well-rounded options for travelers visiting Thailand. It includes unlimited 5G data at maximum speed, unlimited local calls, and 30 minutes of international calling to popular destinations like China, Hong Kong, Taiwan, India, and South Korea. The plans are available for 8, 15, or 30 days, priced at 49, 699, and 1,199 THB respectively (around $12 to $33).
This makes dtac a great option for those who want more than just data — whether you need to make local restaurant bookings or stay in touch with friends abroad. While activation requires visiting a dtac store, the value you get in return—especially with unlimited high-speed internet and calling—is well worth it.
Benefits of dtac eSIM:
How to activate: Go to a dtac store (available in many airports and cities), ask for a Happy Tourist plan, and request activation of eSIM. A staff member will scan a QR code onto your phone and guide you through setup. Make sure to bring your passport and have an internet connection during activation.
