5 Best eSIM Providers for Thailand in 2025

Did you know there were nearly 600 million eSIM smartphone connections worldwide in 2024 — over three times the number in 2022¹? If you're traveling to Thailand, eSIMs have you covered, no matter your needs or preferences. I’ve analyzed everything from speed and coverage to ease of use and even explored Reddit communities for real user feedback to provide well-rounded recommendations.

1. Holiday — Affordable eSIM Plans for Travelers Exploring Thailand

• Regional bundles: Asia eSIM that covers 19 countries, including Thailand
• The lowest price for Thailand: $2.50 for a 5-day plan with 1GB of data
• Supported networks: LTE, 4G, 5G

Holiday is designed for tourists looking for straightforward, budget-friendly connectivity while exploring Thailand. With plans like 1GB, 10GB, and 20GB, it’s excellent for both short and long trips. Coverage spans major cities like Bangkok and Chiang Mai, as well as popular tourist destinations, providing reliable internet access throughout your journey. When I used Holiday in Thailand, it easily unblocked my social media accounts (like YouTube and Daily Mail).

You can cancel an active but unused eSIM data plan within 14 days of purchase

What makes Holiday unique is its focus on ease of use. You can buy and activate your plan before you even leave for your trip, ensuring you have instant internet access as soon as you land. No need to hunt for local SIM cards or deal with complicated setups — just scan the QR code, and you’re ready to go. Plus, managing your plan is a breeze with the user-friendly app, letting you top up or adjust your data anytime.

However, Holiday’s offerings are primarily geared toward data-only use, so it doesn’t include voice or SMS capabilities. Even so, its affordable pricing and extensive coverage make it a top pick for travelers seeking hassle-free internet access in Thailand.

2. Saily — Robust Security Features to Keep Your Data Safe While Traveling in Thailand

Saily, from the team behind NordVPN, is an eSIM service designed with travelers' data security in mind. It lets you choose from 37 virtual locations to keep your actual location private. Plus, it automatically blocks malicious sites and limits trackers, helping you save on mobile data. The best part? These features kick in with any plan — no extra apps or setup needed — making cybersecurity effortless while you travel.

Saily’s privacy features are built directly into the eSIM service

It provides affordable data-only eSIM plans starting at $2.84 for 1GB, valid for 7 days. Saily promises automatic connection upon arrival in Thailand, ensuring you stay connected throughout your journey. It allowed me to use all my favorite social media apps without any hassle while abroad.

One concern raised by some Reddit users is that the connection can be slow and unstable, particularly after the first few days of use. However, most comments highlight a positive experience, with users reporting reliable service and a consistent, high-speed internet connection. Many also mention being able to stream videos and make video calls without any issues, and they plan to use Saily again for future trips.

3. Airalo — Flexible Southeast Asia Packages for Trips to Thailand and Its Neighboring Countries

Airalo makes it affordable and flexible to stay connected and unblock your favorite services while traveling across Southeast Asia. Its Asialink package covers 18 countries in the region, including Vietnam, Cambodia, and Laos — perfect for cross-border travelers. Just note that these are data-only plans.

All Asialink plans come with flexible top-up packages too

However, Airalo also offers a plan designed just for Thailand — the Happy Tourist eSIM, powered by DTAC. It comes with 50GB of data, 100 minutes of local calls, and 15 baht credit for texts and international calls. If you’re a heavy data user, there’s even an unlimited plan option to keep you connected nonstop.

My only gripe is that the Happy Tourist eSIM 50GB plan doesn’t allow top-ups. That said, 50GB is a pretty generous data allowance — perfect for sharing Instagram pictures and browsing the web. But if you’re a heavy streamer or download lots of content, the unlimited data plan might be a better fit for you.

4. Airhub — Unlimited Data Plans and Voice Minutes to Always Stay Connected in Thailand

Airhub eSIM is perfect for people who often travel internationally for work or lifestyle. It offers a variety of plans, whether you need data-only or a combo of voice and text. You can pick the data allowance that suits your trip, from 3GB or 7GB to 500GB or even unlimited — depending on how long you’re staying in Thailand and how much data you’ll need.

Airhub eSIMs work on various Android and iOS devices

Sadly, some Reddit users reported that their speeds were reduced after using a certain amount of data, even when they had purchased unlimited data plans. However, it’s relatively common for providers to advertise unlimited data plans but still apply data throttling after a certain usage threshold is reached. This practice is known as fair usage policy or data deprioritization.

5. GigSky — Provides a Free Plan for Quick Thailand Communication

GigSky eSIM has a great perk for travelers heading to Thailand — 100MB of free data to try it out with no strings attached. So you can test the service’s reliability and convenience before committing. When you’re ready for more, GigSky offers a range of plans, including unlimited data options, to keep you connected. The eSIM makes it easy to access social media platforms and stay in touch with friends back home.

You don’t even need a credit card to activate this feature

The only downside is that GigSky’s plans are a bit pricier compared to other Thailand-specific eSIM providers. However, its reliability and worldwide coverage make it an excellent option for travelers who value convenience and flexibility.

eSIM for Thailand: What to Know Before You Buy

Picking an eSIM for Thailand is all about finding the right mix of coverage, affordability, and ease of use. Look for a provider that works with Thailand's major networks, such as AIS, DTAC, or TrueMove, to ensure solid connectivity throughout the country.

Think about the length of your trip and how much data you'll need — whether you're streaming maps, sharing travel photos, or staying in touch with friends and family. Don’t forget to check the provider’s coverage map to confirm reliability, especially if you’ll be visiting more rural or remote areas. Lastly, choose a provider with easy activation and responsive support in case anything goes wrong during your travels.

Tourist Plans and Pricing

eSIM plans for tourists in Thailand range from budget-friendly to premium, depending on the provider and data package. Most 30-day plans cost between $10 and $40, with higher prices for larger data allowances or plans that cover multiple countries.

Some plans are data-only, while others include voice calling and text messaging. Before buying, check for any hidden fees or overage charges. It’s always a good idea to read the terms and conditions carefully so you’re not caught off guard.

Choosing the Right Data Package

Your ideal data package depends on how long you’re staying and your data habits:

• Short trips (2GB–5GB): Perfect for light users who just need maps, emails, and a bit of browsing.
• Longer stays (10GB or more): Great for heavy data users or those uploading lots of photos and videos.
• Multi-country plans: If you're visiting nearby countries like Vietnam or Cambodia, look for packages that offer coverage across Southeast Asia.

Some providers even let you adjust your plan on the go so you can add more data if needed. Compare speeds, coverage, and reliability to find the best deal for your trip.

Is Your Phone Ready for an eSIM?

Not all phones support eSIMs, so it’s worth checking your device before you buy one. Most newer smartphones from brands like Apple, Samsung, and Google are eSIM-compatible. Your phone also needs to be unlocked to connect with international networks.

Here’s how to check if your phone is eSIM-ready:

For iPhones:

1. Open Settings. Look for the gear icon.
2. Tap Cellular and check for the option to add eSIM.

For Android phones:

1. Open Settings and scroll to the About Phone option.
2. Look for SIM Status or any mention of eSIM/Embedded SIM.

If the Add eSIM option isn’t available, your phone might be too old (pre-2018) or restricted by your carrier. To double-check, visit your phone manufacturer’s website or contact your carrier’s support team. Also, make sure your phone’s software is up to date to avoid any activation issues.

Tips for Using eSIMs in Thailand

Thailand ranks as the 8th most popular tourist destination in the world, known for its vibrant culture, delicious cuisine, and stunning landscapes. In 2024, it was expected to welcome around 36.1 million visitors⁴. Staying connected in Thailand is easy with an eSIM, but it’s helpful to know a few tips to make the most of it. Here’s everything you need to know about activating, managing data, and making sure you stay connected across the country:

• Activate before you arrive. Setting up your eSIM before you land in Thailand is super convenient and guarantees you'll be ready to go as soon as you step off the plane. Most providers let you activate it via their app or website. If you’ve already arrived, don’t worry — you can still activate it at the airport by downloading the provider’s app. Just a heads-up, airport WiFi might charge a small fee.
• Check coverage in remote areas. While places like Bangkok and Chiang Mai are well-covered with excellent eSIM service, rural areas might have patchier connections. To avoid any surprises, double-check your provider's coverage map before heading to remote spots. Providers like Saily give you access to multiple local networks, making it easier to stay connected even in more isolated areas.
• Avoid roaming charges. If you’re using a multi-country eSIM plan, it’s a good idea to adjust your settings to avoid roaming charges as you cross borders. Check your plan’s roaming terms ahead of time so there are no surprises when you’re traveling between countries.
• Monitor your data usage. Keeping track of your data usage is key, especially if you’re on a limited plan. Most eSIM providers offer built-in data usage trackers, so you can easily keep an eye on how much data you’re using — this is especially important if you’re on a longer trip.
• Look for easy top-up options. Running low on data? No problem! Many eSIM providers make it easy to top up your plan directly from their app, so you can add more data without leaving your accommodation or hunting for a physical SIM card.
• Check for local options. For extended trips, it might make more sense to get a local eSIM directly from Thai providers like DTAC or AIS. These often offer the best coverage, plus the ability to recharge and even get a local phone number, which is great if you’re staying for a month or more.

FAQs on the Best eSIM for Thailand

How can I tell if my smartphone supports eSIM?

You can refer to the manufacturer's website or look at the device specifications. Most recent models from Apple, Samsung, and Google support eSIM functionality, but it’s important to have your phone unlocked to use an eSIM from a foreign provider. You can also check your phone’s settings — for example, on an iPhone, you’ll find eSIM options under Cellular in the settings menu. If eSIM isn't listed, your phone may not support it.

Which eSIM option is the most affordable for Thailand?

Holiday is generally considered the most affordable eSIM option for Thailand. It offers affordable plans specifically designed for tourists, with options ranging from 5 to 30 days. Starting at low prices, Saily delivers excellent value without skimping on coverage. Its data packages are perfect for staying connected while keeping costs down, making it a top choice for budget-conscious travelers.

Is it possible to purchase an eSIM at the airport in Thailand?

Yes, it’s possible to purchase an eSIM at the airport in Thailand, but it may not always be the most cost-effective option. Airport kiosks often offer tourist SIM cards and eSIM options, but they tend to be priced higher than what you'd find online or in local stores. To avoid paying a premium, consider purchasing your eSIM before arriving in Thailand, which allows for easier activation and better pricing.

Can I retain my home phone number when using an eSIM in Thailand?

Yes, you can keep your home phone number while using an eSIM in Thailand by setting up a dual-SIM system. Most modern smartphones let you use your physical SIM for your home number and an eSIM for local data and calls at the same time. This means you can still receive calls and texts on your home number while staying connected in Thailand with your eSIM. To avoid any issues, make sure your phone supports dual-SIM functionality and set up your eSIM before you arrive in Thailand.

Are there eSIM plans for Thailand that offer unlimited data?

While some eSIM providers offer plans with large data allowances, truly unlimited data plans for Thailand are rare. Most eSIM plans provide data packages ranging from 5GB to 20GB, with options to top up if needed. However, providers like Airhub offer many unlimited plan options. Be sure to review the terms before purchasing so the plan meets your needs.

Does a Thailand eSIM support 5G connectivity?

Yes, some Thailand eSIM plans support 5G connectivity, but availability depends on your provider and the area you are in. Major networks like AIS and DTAC offer 5G coverage in key cities, such as Bangkok and Chiang Mai. All providers on this list offer 5G support in Thailand.

Can I make phone calls with an eSIM for Thailand?

Yes, you can make phone calls with an eSIM for Thailand, but it depends on the plan you choose. Most eSIM providers offer data-only plans that focus on internet access. However, some providers offer voice call options with their plans, allowing you to make local and international calls via your eSIM. If making calls is essential, check the details of the plan to confirm that it includes voice services, or consider using apps like WhatsApp or Skype for calls over data.

Conclusion

If you're heading to Thailand, an eSIM is a hassle-free way to stay connected without dealing with physical SIM cards. It’s a more flexible, secure, and user-friendly option that lets you avoid swapping cards when crossing borders or changing providers. Plus, you can activate it remotely, saving you time and making setup super easy.

That said, not all eSIM services are created equal. Prices, coverage, and data options can vary, so it’s a good idea to compare providers based on your budget, data needs, and how long you'll be staying. With the options I’ve covered, you’ll be able to choose the perfect eSIM to suit your Thailand trip. So, to wrap up, what's the best value eSIM for Thailand? My top recommendations are Holiday and Saily.
