Thailand’s mix of hyper-connected cities and remote jungles means your phone’s signal can swing from 5G to “no service” fast. While public Wi-Fi exists in tourist hubs, it’s often sluggish or insecure — a headache when booking last-minute ferries to Koh Samui or translating street food menus.
We ran real-world tests across Thailand’s major cities, islands, and transit hubs to find the best eSIMs for speed, coverage, and value. Whether you’re livestreaming the Full Moon Party on Koh Phangan, hopping between Bangkok’s BTS stations, or uploading drone shots from Railay Beach, the right eSIM keeps you online—fast, hassle-free, and without inflated roaming fees.
In this guide, we break down the 6 best eSIMs for Thailand in 2025, including side-by-side comparisons of data plans, hidden fees to avoid, and tips to maximize coverage (even on Railay’s cliffs). Plus, learn which providers include built-in VPNs for accessing region-locked apps and why some “unlimited” plans throttle speeds after sunset.
Internet access in Thailand isn’t always as open as you’d expect. Over 100,000 websites have been blocked by Thai authorities in the past, including popular international news outlets, social media groups, and even Wikipedia pages. Content deemed politically sensitive or critical of the monarchy can vanish without warning.
During times of unrest, entire platforms like Facebook and YouTube have faced government-ordered takedowns, leaving travelers suddenly cut off from apps they rely on daily.
An eSIM gives you more than just connectivity — it gives you choice. With the right eSIM, you can connect to global carriers that bypass local ISP censorship and throttling. That means uninterrupted access to Google Maps, encrypted messaging apps, VPNs, cloud storage, and any site you need for work, travel, or staying in touch — regardless of what’s blocked on Thai networks.
Relying on hotel Wi-Fi or trying to sort out a local SIM in Thailand sounds easy—until it isn’t. Spotty connections, registration hassles, language barriers, and inconsistent speeds can turn a simple task into a headache. If you’re working remotely, streaming, or just want to stay online without drama, local options don’t always cut it. That’s where international eSIMs make a big difference.
Getting connected in Thailand is refreshingly easy, and the experience often surprises first-timers with just how modern and efficient it is. Right from the airport, you’ll find mobile providers like AIS, DTAC, and TrueMove H ready to set you up with a prepaid SIM card that includes generous data—sometimes unlimited—and affordable voice plans.
The process takes minutes, and with your passport in hand, you’re good to go. For most of the time, the mobile signal is strong and data speeds are fast. Thailand’s mobile network is one of Southeast Asia’s best, with 4G nearly everywhere and 5G coverage expanding quickly in urban centers.
Wi-Fi is equally easy to find. Cafés, restaurants, co-working spaces, shopping malls, and even roadside coffee stands often offer free internet. If you’re planning a longer stay and need home internet, fiber-optic options are widely available in cities. Companies like AIS Fibre and TrueOnline offer fast speeds at low monthly rates, and installation is typically quick and painless.
For communication, the go-to app isn’t WhatsApp—it’s LINE. It’s what locals use for everything from texting friends to booking food, and it’s essential if you want to stay in sync with Thai contacts. Social media is thriving too—Facebook, Instagram, and TikTok are huge here, and they’re often where small businesses and freelancers operate.
One thing to be aware of: while the internet is mostly open, Thailand does block some content, particularly anything considered offensive to the monarchy or related to gambling. A VPN is a smart move, especially if you want full access to international content or to keep your browsing private.
When choosing an eSIM for Thailand, a few key things can make the difference between smooth, reliable service and constant frustration. Here's what really matters—clearly and simply:
1. Coverage matters more than you think.
Not all eSIMs connect to the same local networks. The best ones partner with top Thai carriers like AIS, DTAC, or TrueMove H. These give you strong, stable service in cities, on islands, and even in more remote areas.
2. Data speed isn’t just a number.
A plan that says "high-speed data" isn't helpful if it slows to a crawl after 2GB. Look for eSIMs that offer full-speed data with a fair cap—or unlimited at usable speeds—especially if you stream, work online, or use maps and apps constantly.
3. Price vs. value.
Cheap is tempting, but you often get what you pay for. A few extra dollars can get you better support, better speeds, and fewer headaches. Avoid deals that sound too good—they often come with slow data or unreliable connections.
4. Hotspot and tethering rules.
Not all eSIMs let you use your phone as a hotspot. If you plan to connect a laptop or tablet, check this detail before you buy—it’s not always obvious.
5. Activation should be quick and painless.
The best eSIMs let you scan a QR code, follow a few steps, and get connected in minutes. No apps you don’t need. No waiting. No complicated setup.
6. Censorship and VPN compatibility.
Thailand has internet restrictions, especially around political content and gambling. Make sure your eSIM doesn’t block VPNs if privacy or content access matters to you.
In short: go for an eSIM that partners with strong Thai networks, offers clear data limits, allows tethering, and works right out of the box. Simple, reliable, and built for how you actually use your phone. If you want help picking the top ones available right now, keep on reading.
If you're planning a trip to Thailand in 2025 and want to stay connected without the hassle of physical SIM cards, here are the top eSIM providers to consider:
Holafly is a solid option if you want to skip the hassle of finding a local SIM in Thailand and just get online right away. Once you buy a plan, they email you the eSIM instantly—just scan the QR code, turn on data roaming when you land, and you're connected. No app download, no language barrier, no searching for kiosks at the airport.
In Thailand, Holafly connects through major local networks like AIS, which means good coverage and fast speeds in cities like Bangkok, Chiang Mai, and even popular islands like Koh Samui or Phuket. You get unlimited data, so you don’t need to worry about topping up or tracking your usage—though if you plan to use a hotspot, you’re limited to 500MB per day.
Plans run from 1 to 90 days, and the daily cost gets lower with longer durations. It’s data-only—no local number or SMS—but if you use WhatsApp, FaceTime, or similar apps, you won’t notice the difference.
It works with most newer smartphones, and Holafly offers clear, well-written guides that explain which devices support eSIM. Even if you’re not especially tech-savvy, you’ll find the information straightforward and easy to follow—no deep digging required.
Holafly is simple, fast to set up, and removes a lot of the friction that can come with staying connected abroad. It’s not the cheapest option, but for many travelers, the convenience is worth the extra few bucks.

| Unlimited | $20.90 | 5 days |
| Unlimited | $50.90 | 15 days |

Pros
✅ Truly unlimited data without the need to monitor usage

✅ Reliable coverage across Thailand, including major cities and tourist areas
Cons
❌Does not include a local Thai phone number or SMS capabilities
We’ve tested Holafly’s eSIM in action—see the video below to check out the results.
Ubigi is a convenient choice for travelers seeking to avoid the hassle of purchasing a local SIM in Thailand. After selecting a plan, you’ll receive an eSIM via email or through their app. Scanning the QR code and enabling data roaming will connect you upon arrival.
While setup is generally quick, Ubigi requires downloading their app for activation and management—a step some users might find unnecessary. Coverage in Thailand relies on major providers like AIS and DTAC, ensuring strong 4G speeds in cities like Bangkok and tourist hotspots like Phuket. However, 5G access is not consistently available, which may affect speed in areas with advanced networks.
While unlimited data plans are available, the options are very limited. Most plans come with fixed data allowances (e.g., 3GB, 5GB, 10GB), so heavy users or streamers may need to opt for the higher-tier unlimited plans—if available. The eSIM is data-only, with no local number or SMS, though messaging apps like WhatsApp work seamlessly.
For budget-conscious travelers with minimal data needs, Ubigi offers a functional solution. However, strict data limits and app dependency may deter those seeking simplicity or heavy usage.
Key features
| Data | Price | Validity |
| 1 GB | $5 | 7 days |
| 3 GB | $9 | 15 days |
| 10 GB | $18 | 7 days |
| 10 GB | $22 | 30 days |
| Unlimited | $29 | 7 days |
| 25 GB | $42 | 30 days |
Pros
✅ Affordable short-term plans for light data users
✅ Reliable 4G coverage in urban and tourist areas
✅ No physical SIM—keep your original number for calls
✅ Easy app-based management (for tech-savvy users)
Cons
❌ Data can run out quickly on heavy use
❌ No voice or SMS (data-only service)
❌ Customer support not available 24/7
Nomad eSIM is a practical choice for travelers prioritizing affordability and flexibility. After purchasing a plan, you receive an eSIM via email—scan the QR code, activate data roaming, and connect upon arrival. Setup is straightforward, though Nomad lacks detailed troubleshooting guides, which might frustrate less tech-savvy users.
Coverage in Thailand uses networks like DTAC and TrueMove, providing reliable 4G in cities like Bangkok and islands like Phuket. However, 5G support is sporadic, even in areas with advanced infrastructure.
A major recent update: Nomad now offers unlimited data plans in addition to its traditional capped data tiers. This makes it a much more viable option for heavy users—such as those streaming video, using GPS frequently, or relying on cloud-based apps during their stay. Pricing for unlimited plans is still competitive compared to alternatives like Holafly, especially for short- to mid-term stays.
Plan flexibility is a mixed bag. While Nomad covers durations from 7 to 30 days, some users wish for more tailored options, especially for longer or irregular travel. Others have expressed frustration over not being able to pause or extend plans on demand. Additionally, although Nomad allows hotspot usage on most plans, this feature is sometimes restricted or throttled—details that aren’t always clear upfront.
Key features
| Data | Price | Validity |
| 1 GB | $5 | 7 days |
| 10 GB | $12 | 30 days |
| 50 GB | $12 | 10 days |
| Unlimited | $20 | 10 days |
| Unlimited | $19 | 15 days |
| Unlimited | $30 | 33 days |
Pros
✅ Now offers unlimited data options
✅ Simple QR code setup—no app needed
✅ Budget-friendly for short-term stays
✅ Reliable coverage in most tourist zones
✅ Works in parallel with your main SIM
Cons
❌ 5G remains inconsistent, even in metro areas
❌ Email-only support with slow response times
❌ Manual APN setup may be required on older devices
❌ Hotspot functionality limited on some unlimited plans
BNESIM is a flexible eSIM option that works well for both short vacations and longer trips. Once you buy a plan, the eSIM arrives by email—just scan the QR code, turn on data roaming, and you're good to go. Setup is easy, especially if you use the BNESIM app, which helps manage your plan and settings.
In Thailand, BNESIM connects to major networks like DTAC and AIS, offering solid 4G and even some 5G in big cities like Bangkok and tourist spots like Chiang Mai or Phuket. 5G isn't everywhere yet, but 4G speeds are reliable for most travelers.
One of BNESIM’s standout features is its plan variety. You can choose from capped data plans or pay-as-you-go setups that don’t expire—ideal for flexible or long-term travel. However, BNESIM does not currently offer unlimited data plans in Thailand.
Even in regions where "unlimited" is available, it usually comes with a 24GB high-speed cap, after which speeds drop drastically to 128kbps. That’s far too slow for anything beyond basic messaging. So if you’re planning to stream, video call, or work remotely in Thailand, it’s better to opt for a large capped plan or look at other providers that truly offer unlimited, high-speed options in the country.
Key features
| Data | Price | Validity |
| 1 GB | €2.88 | 30 days |
| 3 GB | €6.73 | 30 days |
| 5 GB | €13.53 | 30 days |
| 10 GB | €25.90 | 30 days |
| 20 GB | €50.56 | 30 days |
Pros
✅ Very affordable starting prices
✅ Wide global coverage (170+ countries)
✅ Hotspot supported
✅ 24/7 live chat and WhatsApp support
Cons
❌ Website interface can be confusing
❌ Doesn’t offer unlimited plans for Thailand
❌ Plan durations mostly limited to 7 or 30 days
❌ Android activation can be tricky for first-timers
Airalo is one of the most popular eSIM options worldwide, and it’s easy to see why. If you’re heading to Thailand, Airalo offers solid value with flexible data plans, instant activation, and reliable coverage through top Thai networks like AIS and DTAC. Plans start as low as $4.50, and setup takes just a few taps—scan the QR code, enable data roaming, and you’re connected.
There’s no app requirement (though one is available if you want to track usage), and Airalo is known for offering a wide range of affordable capped data plans—from 1GB up to 20GB. It’s perfect for travelers who want just enough data to navigate, post, and stay in touch—without paying for more than they’ll use.
However, despite the smooth setup and attractive pricing, Airalo has received criticism for inconsistent customer support. Some users mention slow or unhelpful responses when facing technical issues—especially when plans fail to activate correctly or QR codes don’t work. While the majority of experiences are positive, this could be frustrating if you run into trouble while abroad and need fast help.
It’s also worth noting that Airalo doesn’t offer unlimited data plans for Thailand—so if you’re planning on streaming, working remotely, or using a lot of hotspot data, you may hit limits quickly.
Key features
| Data | Price | Validity |
| 1 GB | $4.50 | 7 days |
| 2 GB | $5 | 15 days |
| 3 GB | $6 | 30 days |
| 5 GB | $8 | 30 days |
| 10 GB | $12 | 30 days |
| 20 GB | $18 | 30 days |
Pros
✅ Budget-friendly data plans
✅ Instant setup with no app required
✅ Strong network performance across Thailand
✅ Works on most modern phones
✅ Supports tethering and hotspot
Cons
❌ No unlimited data options for Thailand
❌ Customer support can be slow or unresponsive
❌ No voice or SMS functionality (data-only)
❌ Not ideal for heavy streamers or digital nomads
Maya is especially appealing if you’re hopping across Southeast Asia or staying longer in Thailand—because unlike many eSIMs that expire after a week or two, Maya plans stay active for up to 180 days, giving you the freedom to come and go without reinstalling or repurchasing.
Setup is seamless: once you buy a plan, you’ll get a QR code by email—just scan it, activate data roaming, and you're connected. No app required. No hunting for SIM kiosks. And no dealing with Thai paperwork or language barriers.
In Thailand, Maya taps into reliable local networks like TrueMove and AIS, giving you steady 4G coverage in Bangkok, Chiang Mai, Phuket, and most tourist-heavy islands. That said, Maya doesn’t currently offer unlimited data plans, so if you're planning on constant video streaming or hotspotting for work, you'll want to choose a higher-cap plan (up to 40GB). Speeds are solid, but as with many providers, performance may dip slightly in rural areas or during peak hours.
Maya’s real selling point is simplicity + flexibility: long validity, fair prices, and plans that just work. And if something goes wrong? Their refund policy is generous (up to 180 days), which is not something most providers can say.
However, not everything is perfect. Some users complain about Maya’s customer service, as they can be slow to respond, especially if you run into technical hiccups. Also, there’s no mobile app for managing your data—you’ll need to log in through the website to monitor usage or top up, which might be inconvenient if you're on the move.
Key features
| Data | Price | Validity |
| 1 GB | $5.99 | Up to 180 days |
| 3 GB | $8.99 | Up to 180 days |
| 5 GB | $10.99 | Up to 180 days |
| 10 GB | $14.99 | Up to 180 days |
| 20 GB | $23.99 | Up to 180 days |
| 40 GB | $35.99 | Up to 180 days |
Pros
✅ Longest plan validity (up to 6 months)
✅ Easy QR code setup—no app or extra steps
✅ Strong network partners in Thailand
✅ Hotspot allowed on most plans
Cons
❌ No unlimited data options
❌ No mobile app for data tracking
❌ Customer support can be slow, according to user reviews

Choosing the best eSIM for Thailand isn’t about picking the cheapest plan off a list—it’s about finding what actually works in the real world. We combined first-hand travel experience, deep product testing, and crowdsourced feedback to create this guide.
Here’s how we vetted every eSIM on this list:
From Bangkok’s BTS stations to the beaches of Koh Phi Phi, we tested eSIMs in major cities, remote islands, and everywhere in between. We looked at how quickly they activated, how stable the connections were, and whether promised speeds actually held up on the ground.
We prioritized eSIMs that partner with Thailand’s top carriers—AIS, DTAC, and TrueMove H—to ensure stable 4G/5G coverage. If an eSIM didn’t reliably connect to these networks, it didn’t make the cut.
Hidden fees? Daily throttling? Auto-renewals you can’t cancel? We looked beyond the headline prices to understand what you're actually paying for—and made sure every recommendation offers clear, upfront pricing with no surprises.
We dug through hundreds of verified reviews on Trustpilot, Reddit, and app stores to identify recurring problems like poor customer service, buggy activation, or unreliable refunds. If travelers consistently flagged an issue, we flagged it too.
We only included providers with a proven track record of working smoothly on eSIM-compatible devices, especially popular models like iPhones and Samsungs. We also favored services that offered QR-code setup, in-app management, or both—so you’re not stuck guessing at a crucial step.
We gave bonus points to eSIMs with built-in VPNs (useful in countries with internet restrictions), hotspot support, delayed activation, and flexible top-up options. These are the small things that make a big difference when you're abroad.
To know if your device is eSIM-compatible, here’s a simple checklist:
How to check your phone:
On iPhone:
On Android (Samsung/Pixel):
You can also dial *#06# — if your device shows an EID number, it supports eSIM.
The best time to order your eSIM is 1–3 days before your trip. That gives you time to install it while you still have reliable Wi-Fi and access to any setup guides or support if needed. Most eSIM providers deliver your plan instantly via email, complete with a QR code or in-app installation instructions.
Before you fly, it’s smart to install your eSIM and double-check your gear—including the correct Thailand plug type for your charger.
Here’s how to activate it (step-by-step):
Once you land, your phone connects to a local network—you’re online within seconds. This setup also lets you keep your regular SIM active for calls or texts if your phone supports dual SIM.
All six of these eSIM providers are solid picks, depending on your travel style. If you're on a tight budget, Airalo, Maya, and BNESIM offer great value with flexible, low-cost plans. Nomad gives you decent data limits with simple setup, while Ubigi works well for lighter users looking for app-based control.
But if your top priority is hassle-free, unlimited connectivity from the moment you land—without worrying about data caps or blocked apps—Holafly consistently comes out ahead.
Its unlimited data, simple QR-code activation, and built-in VPN (which helps bypass Thailand’s content restrictions) make it especially appealing for travelers who work remotely, stream often, or just want things to work without fiddling with settings. Add 24/7 live support, compatibility with most newer phones, and fast setup—and it’s easy to see why so many travelers trust Holafly first.
Holafly is the top pick for most tourists—especially if you want unlimited data and built-in VPN access to bypass content restrictions in Thailand. It’s super easy to set up, works instantly, and connects to top local networks like AIS.
Yes—and you should. Installing your eSIM before you fly ensures you're connected the second you land. Most providers email you a QR code—just scan it, activate data roaming, and you're online. No SIM swaps, no airport kiosks, no stress.
Absolutely—especially in Thailand. eSIMs are cheaper than roaming, more secure than public Wi-Fi, and way more convenient than buying a local SIM. They let you stay connected, access maps, book rides, use translation apps—and in some cases, bypass internet censorship with built-in VPNs.
