Best eSIMs for Thailand 2025: Comparison, Prices, and Recommendations

Staying connected in Thailand isn’t just about convenience, it’s about having reliable data. And in 2025, eSIMs are the easiest way to get online instantly without airport kiosks, paperwork, or the risk of spotty hotel Wi-Fi.

We compared the top providers based on what really matters: price, data options, coverage on Thailand’s strongest networks and how easy they are to set up. Beyond the basics, we also looked at hidden limits, hotspot rules, and whether providers support VPNs to help bypass local internet restrictions.

Holafly stands out with unlimited data and built-in VPN support, Airalo and Nomad deliver excellent budget value, Maya is the go-to for longer stays with flexible validity, and BNESIM gives travelers pay-as-you-go freedom. 

Thailand eSIM prices and data plans

Thailand’s eSIM prices vary widely depending on how much data you need and how long you’re staying, but the main differences come down to speed, coverage, and extras like hotspot use or VPN access. 

Best 6 eSIMs for Thailand

Thailand has plenty of eSIM choices, but not all of them suit the same type of traveler. Some focus on unlimited data, others on budget pricing, flexibility, or long-term validity. To help you pick the right one, we’ve compared the six best providers and highlighted what each does best.

1. Holafly: best for unlimited data + hassle-free setup

Holafly is the go-to choice for travelers who want unlimited data from the moment they land, without worrying about top-ups, kiosks, or activation headaches.

In Thailand, Holafly connects to AIS, one of the country’s strongest networks, ensuring solid 4G/5G coverage in big cities. Setup is instant: purchase online, receive a QR code by email, scan, and you’re connected. No app required, though hotspot use is capped at 500MB per day.

Key features

• Instant activation via QR code (no app needed)
• Unlimited mobile data (hotspot capped at 500MB/day)
• Partners with AIS for reliable nationwide coverage
• Flexible plans from 1 to 90 days
• 24/7 live chat customer support

Pros

• Unlimited data you don’t have to track
• Setup takes minutes
• Keep your physical SIM for calls/texts
• Strong coverage in both cities and tourist areas

Cons

• Data-only (no Thai phone number or SMS)
• Hotspot use limited to 500MB/day
• More expensive than capped-data alternatives

Verdict: Holafly is best for travelers who want unlimited, no-stress data in Thailand with instant setup. It costs more than capped-data options, but the simplicity and reliability make it worth it if convenience is your priority.

2. Ubigi: best for app-based control & light data users

Ubigi is a solid option if you want affordable, capped data plans with app-based management. It’s easy to set up, reliable in tourist areas, and best suited for travelers with light or moderate data needs.

In Thailand, Ubigi connects through major local networks like AIS and DTAC, offering dependable 4G coverage and partial 5G access in urban centers. 

Activation requires the Ubigi app, where you also buy, install, and monitor your plan. While setup is straightforward, unlimited options are limited, most users will be choosing fixed-data bundles.

Key features

• App-based setup and management required
• Works on AIS and DTAC networks with 4G coverage
• Some plans include 5G in select areas
• Offers capped data bundles and limited unlimited plans
• Tethering allowed on most plans
• App shows real-time data usage

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

Verdict: Ubigi is a good fit for budget-conscious travelers who only need light to moderate data and don’t mind using an app for setup. It’s less ideal for heavy users, as unlimited choices are limited and support isn’t always responsive.

3. Nomad: best for budget flexibility 

Nomad offers a strong balance of affordability and flexibility, with new unlimited options making it attractive for both casual users and heavier data needs.

In Thailand, Nomad eSIM connects to DTAC and TrueMove, two of the country’s major networks, ensuring reliable 4G in cities and on popular islands. 

5G support is inconsistent, but setup is simple, just scan the QR code from your email and activate roaming. While hotspot use is allowed on many plans, some unlimited tiers come with restrictions or throttling.

Key features

• QR-code activation only (no app required)
• Capped and unlimited plans available
• Runs on DTAC and TrueMove networks (reliable 4G, limited 5G)
• Hotspot supported, though restricted on some unlimited tiers
• Flexible durations (7–33 days)
• Email-only support (no live chat, slower response)

Pros

• Now offers unlimited data options
• Reliable coverage in most tourist zones
• Works in parallel with your main SIM

Cons

• Email-only support with slow response times
• Manual APN setup may be required on older devices
• Hotspot functionality limited on some unlimited plans

Verdict: Nomad is ideal for budget-conscious travelers who want flexibility and the option of unlimited data without overpaying. It’s best suited for those comfortable with self-service setup and email-only support.

4. BNESIM: best for flexible pay-as-you-go options

BNESIM is one of the most flexible eSIM providers for Thailand. It’s ideal if you want cheap starter plans, the freedom of no-expiry data, or you travel often across multiple countries.

In Thailand, BNESIM connects to AIS and DTAC for steady 4G and some 5G in cities. Setup is quick and the app makes it easy to top up or track usage. While it doesn’t offer unlimited data, BNESIM stands out with a choice between 30-day bundles and lifetime no-expiry plans.

The bundles work like standard prepaid SIMs: once activated, you have 30 days to use your data before it expires. Lifetime plans, on the other hand, act like a data wallet: you buy data once, and it never expires until you use it.

Key features

• Choice of 30-day bundles or lifetime (no-expiry) data
• Works in 170+ countries with regional and local plans
• Auto-renews when data is almost out
• Buy and manage via mobile app or website
• Most plans support tethering
• Help available via chat, WhatsApp, or email

Pros

• Very affordable starting prices
• True no-expiry data
• Hotspot supported

Cons

• Website interface can be confusing
• Doesn’t offer unlimited plans for Thailand
• Bundles mostly locked to 30-day durations

Verdict: BNESIM is one of the most flexible eSIMs you can get in Thailand. If you just need short-term data, the 30-day bundles are cheap and easy. But the real highlight is the lifetime no-expiry plans: buy once, and your data balance stays active until you use it, even months or years later.

5. Airalo: best for budget-friendly data plans

Airalo is one of the most popular global eSIM providers, offering affordable capped-data plans with easy setup and reliable coverage on Thailand’s strongest networks.

In Thailand, Airalo partners with AIS and DTAC to deliver dependable 4G/5G coverage across cities and tourist areas. Activation is simple: purchase online, receive a QR code by email, and scan to connect. 

There’s no unlimited plan for Thailand, but the range of affordable capped options (1GB–20GB) makes it a favorite for budget travelers and short stays.

Key features

• eSIM delivered instantly via email
• Great value with plans starting under $5
• Connects to top Thai networks like AIS and DTAC
• Choose from 1GB up to 20GB
• Tethering allowed on most plans
• Manage plans via web or app

Pros

• Budget-friendly data plans
• Instant setup with no app required
• Strong network performance across Thailand

Cons

• Customer support can be slow or unresponsive
• Not ideal for heavy streamers or digital nomads

Verdict: Airalo is best for budget travelers who need affordable data in Thailand without overpaying for unlimited. It’s an excellent low-cost option for light to moderate use, though not suited for those who stream heavily or need long-term unlimited data.

6. Maya Mobile: best for long validity plans

Maya Mobile is perfect for travelers who want long-lasting data plans that stay active for up to *180 days, ideal for extended stays or slow travel across Thailand and Southeast Asia.

*All Maya Mobile plans last 5 days from activation, regardless of the data allowance. The mention of “180 days” refers only to the activation window, meaning you can buy the eSIM now, and you’ll have up to 6 months to decide when to activate it.

In Thailand, Maya connects through TrueMove and AIS, delivering steady 4G coverage in cities like Bangkok, Chiang Mai, and Phuket, as well as popular islands. 

Setup is simple via QR code, and hotspot use is supported on most plans. While most Maya plans are capped (up to 100 GB), they also offer a single unlimited option, giving travelers both flexibility and peace of mind.

Key features

• Plans last up to 180 days
• Setup via email and QR code
• Connects to major Thai networks like AIS and TrueMove
• Use your data across devices (on most plans)
• Up to 6 months to request a refund if unused

Pros

• Longest plan validity (up to 6 months)
• Strong network partners in Thailand
• Hotspot allowed on most plans

Cons

• All plans expire after 5 days, regardless of data size
• No mobile app for data tracking
• Customer support can be slow, according to user reviews

Verdict: Maya Mobile is the best choice for long-term or flexible travelers who don’t want their data plan to expire quickly. It lacks unlimited data, but the long validity and fair refund policy make it ideal for extended stays or multi-stop trips in the region.

Why you need an eSIM in Thailand: internet, roaming, Wi-Fi

• Local internet realities: Online access in Thailand can feel unpredictable. Certain news sites, apps, and even whole platforms sometimes disappear overnight, leaving travelers suddenly cut off.
  
• Why roaming and Wi-Fi fall short: Relying on roaming racks up huge bills, and “free” Wi-Fi in hotels or cafés is usually sluggish and insecure; fine for checking messages, but not when you actually need speed and stability.
  
• How an eSIM makes the difference: With a quick QR scan, you’re online immediately through Thailand’s best networks. Some providers even bundle in VPN access, so you can bypass restrictions and stay connected with the same freedom you’d expect at home.

Where and how to buy an eSIM for Thailand

1. Online before your trip: The easiest option is to buy from a global eSIM provider.
   
   1. Holafly gives you unlimited data with VPN support
   2. Airalo is great for cheap capped plans
   3. Nomad now offers both budget and unlimited options
   4. Ubigi works well if you like app-based control
   5. BNESIM is flexible with pay-as-you-go, and 
   6. Maya Mobile lets you activate anytime within 180 days, ideal if you want to plan ahead.
      
2. On arrival (local carriers): Thailand’s main providers (AIS, DTAC, and TrueMove H) offer prepaid SIMs and eSIMs at airports, malls, and convenience stores. Setup is quick, but you’ll need your passport for registration, and staff may not always speak English fluently outside tourist hubs.

Pro tip: Buying online is the simplest route because that way you land with data already working. Just remember to save your QR code and activation details offline so you can install your eSIM the moment you arrive.

How to activate an eSIM for Thailand

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. 

Before you fly, it’s smart to install your eSIM and double-check your gear: including the correct Thailand plug type for your charger. If you’re planning to use a VPN, download and test it at home first, since some apps may be harder to access once you’re in Thailand.

Here’s how to activate it (step-by-step):

1. Purchase your eSIM from your chosen provider
2. Receive the QR code by email (or install via app)
3. Scan the QR code using your phone’s camera through Settings
4. Follow on-screen prompts to add it as a mobile plan
5. Turn on data roaming when you arrive in Thailand

Once you land, your phone connects to a local network, you’re online within seconds. If your phone supports dual SIM, you can keep your regular SIM active for calls/texts while using your eSIM for data, so you don’t miss important messages while staying connected on the go.

How do I know if my device is eSIM-compatible?

To know if your device is eSIM-compatible, here’s a simple checklist:

• iPhone: All models from iPhone XS and newer support eSIM (except some regional variants like Chinese models).

• Samsung: Most Galaxy S20 and newer (S, Note, Fold, Flip series) have eSIM support, but some carrier-locked or regional versions don’t.

• Google Pixel: Pixel 3 and newer support eSIM; again, avoid US Verizon/AT&T-locked versions, which might be disabled.

• Motorola, Huawei, Oppo, Xiaomi, Sony, etc.: Select newer flagship models support eSIM, but check model-specific info carefully.

How to check your phone:

On iPhone:

• Go to Settings > Cellular > Add Cellular Plan
• If you see that option, your phone supports eSIM
• Dial *#06# and if an EID number appears, your device is eSIM-ready

On Android:

• On Samsung: Settings > Connections > SIM Manager > Add eSIM
• On Pixel/others: Settings > Network & Internet > Mobile Network > Download SIM
• Dial *#06# and if an EID number is displayed, your device supports eSIM

Insider tips for your Thailand eSIM

1. Install before you fly: Set up your eSIM at home while you still have stable Wi-Fi.
   
2. Use the provider’s app (if available): Handy for checking data use, topping up, or getting quick support.
   
3. Check for delayed activation: Some providers let you choose your start date—perfect for buying early.
   
4. Enable data-saving settings: Turn on low-data mode or restrict background app refresh to stretch your allowance.
   
5. Sort out your VPN in advance: Download and test it before arriving, as some VPN apps may be harder to access in Thailand.
   
6. Confirm device compatibility: Not every phone supports eSIM; check settings for “Add eSIM” or an EID number.
   
7. Know your hotspot limits: Some “unlimited” plans cap tethering (e.g., 500MB/day), so plan accordingly.
   
8. Avoid common pitfalls: Don’t delete your eSIM profile once installed, and always save your QR code offline in case you need to reinstall.

eSIM vs. physical SIM card in Thailand

Both eSIMs and physical SIMs will get you connected in Thailand, but the experience is very different. An eSIM can be set up before you fly and activated the moment you land, while a physical SIM requires an in-person purchase, ID verification, and often a bit of extra hassle. 

Here’s how they compare:

How we chose the best eSIMs for Thailand

Here’s how we vetted every eSIM on this list:

• 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 to ensure stable 4G/5G coverage. If an eSIM didn’t reliably connect to these networks, it didn’t make the cut.

• 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 gave bonus points to eSIMs with built-in VPNs (useful in countries with internet restrictions), hotspot support, delayed activation, and flexible top-up options. 

Verdict: What is the best eSIM for Thailand?

The right eSIM really depends on how you travel. Thailand has excellent networks, but your priorities (unlimited data, budget, flexibility, or privacy) make all the difference. 

After testing and comparing the top providers, here’s the simple breakdown:

• Unlimited / heavy users → Holafly (true unlimited data, built-in VPN, easy setup)
  
• Budget / short trips → Airalo or Nomad (cheap capped plans, good for light to moderate use)
  
• Multi-network / flexibility → BNESIM (pay-as-you-go, works in 170+ countries, solid for multi-stop trips)
  
• Privacy / VPN-first → Holafly (includes VPN support to bypass Thai content blocks)
  
• Long stays → Maya Mobile (activation window up to 180 days, fair refund policy, hotspot supported)

And while each provider has its strengths, Holafly consistently delivers the smoothest, most reliable experience overall, making it the standout choice for most travelers heading to Thailand.
