Best eSIM for Thailand in 2026: 6 Providers Compared by Price and Data

If you are landing in Thailand and want mobile data before you clear immigration, here is the short answer from the plans as of November 2026: a week of 2GB-a-day data is $6.90 at eSIMX, 30GB for 30 days is $18.80 at eSIMX, and the biggest short-stay plan I found is 100GB for 10 days at $15.99 at eTravelSIM. Seven-day unlimited plans that are not described as a daily allowance run from $12.99 to $27.50 across four providers. I compared six providers using each company’s own Thailand page, so you can match a plan to how you will actually use your phone.

I run Ecommerce Paradise, where I teach people to build high-ticket stores they can manage from a laptop. Thailand is a popular base for people who work remotely, and a store owner needs data that works the moment the plane lands. This is a plans-as-listed comparison, not a hands-on test. I have not used these eSIMs in Thailand, I say nothing about real-world signal or speed, and I flag every spot where a page left out a number or disagreed with itself.

Disclosure: some links below are affiliate links, which means I may earn a commission at no extra cost to you. The links on eSIMX, Amigo eSIM, eTravelSIM and iRoamly go through my own ecommerceparadise.com redirects, so weigh my opinions with that in mind. Every other provider link goes straight to that company’s own Thailand page, and the “best for” labels are my opinion based on published terms.

Best eSIM for Thailand at a Glance (November 2026)

Prices are US dollars as shown on each provider’s Thailand page. “Not shown” means the page I loaded did not display the figure, so check the provider before you buy. “Unlimited” means very different things between companies, which is why the plans column spells out the structure. Plans are 30-day only where I say so, and many of the biggest plans last 7 to 10 days.

My short take, which is opinion and not a test result: eSIMX lists the lowest per-GB figure I calculated among 30-day fixed plans, 30GB for $18.80 at about $0.63 per GB. For a short, data-heavy stay, eTravelSIM lists 100GB for 10 days at $15.99 and eSIMX lists 50GB with SMS for 10 days at $7.90, both about $0.16 per GB. If your trip is mostly maps, email and a store dashboard, a fixed data plan is usually the cheaper route than an unlimited plan.

How I Chose These Six

I started with eSIM providers that publish a dedicated Thailand page and loaded each one’s own page. I kept the six that showed enough plan detail to compare. Everything below is based on each company’s published pages, not on a test of signal in Bangkok, Chiang Mai or on an island, so I say nothing about the speeds you will see in real life.

My criteria were price per gigabyte, how the plan defines “unlimited”, hotspot rules, whether calls or a number are possible, how validity starts, refund terms and how clearly the page named the networks. I also looked for contradictions, because eSIM pages often disagree with their own FAQs. Where they did, I say so and tell you to confirm at checkout. Prices are written as the pages showed them (as of November 2026), and the per-gigabyte and per-day figures are my own arithmetic, labeled as examples.

Airalo, iRoamly and Ubigi did not make the six. Airalo’s page labels every Thailand plan “UnlimitedGB” without defining the term and left out hotspot, refund and call terms, so it gets a short note near the end. iRoamly’s Thailand page listed one plan, and Ubigi’s Thailand plans did not appear in the content I could read.

What the Official Sources Say Before You Buy

Phone compatibility comes first, because no plan helps if your handset cannot use it. Apple’s eSIM and dual SIM support page lists the iPhone XS, XS Max, XR or later as supporting eSIM. For two carriers on one phone, it says your carrier must unlock the iPhone unless both plans come from the same carrier.

It also says the iPhone can use one cellular data network at a time. Apple describes Dual SIM as two active phone numbers or SIMs, so a home line can stay active for calls and texts while a travel eSIM carries data. eSIMX, eTravelSIM and Amigo eSIM each state on their Thailand pages that the phone must be unlocked, and Saily says the device must not be carrier-locked. I treat that as a safe rule for every plan in this guide. Android phones vary by maker and model, so use the compatibility link on each provider’s page.

SIM registration and ID rules in Thailand

I could not verify Thai SIM registration or tourist SIM rules from an official government or regulator page, so I am not stating any as fact. Here is only what the vendor pages say, and it is not a legal answer. eSIMX’s Thailand page says outgoing calls and SMS on its 8-day unlimited-with-calls plan require KYC at a TRUE store, and it shows no other ID requirement. iRoamly’s page lists “ID verification required” without saying what ID or what step.

eTravelSIM’s page says no documentation is needed, while its FAQ says a passport or government ID may be requested if a transaction is flagged. Saily’s page makes no ID claim for its eSIM and says only that physical SIM purchases in Thailand may require a passport or ID. The Nomad, Amigo eSIM, Airalo and Holafly pages did not show an ID requirement in what I read. Treat all of that as “not verified”, and check at checkout.

Data-Only eSIM vs a Plan With Calls

Most travel eSIMs are data only. You get internet, not a phone number. Calls and texts then run through apps such as WhatsApp, LINE or FaceTime, and the Holafly and Saily Thailand pages say so. That works for most visitors, because your home number stays on your regular SIM for incoming calls and codes.

Where it breaks is anything that needs a local number: restaurant confirmations by text, a driver who calls the room, a supplier who prefers a regular phone call. These listed options are the exceptions.

• eSIMX lists a 15GB plan with calls for 7 days at $6.90, a 50GB plan with SMS for 10 days at $7.90 and an unlimited plan with calls for 8 days at $10.90. Each shows free incoming calls, and the page says outgoing calls and SMS on the 8-day plan need KYC at a TRUE store.
• Amigo eSIM’s page shows a 25GB, 30-day plan with calls and texts, but no price appeared next to it, and the number type was not stated.
• Saily’s page says calls and SMS require a Saily phone number plus a text or minutes plan, with prices not shown.
• Nomad’s page says some of its eSIMs include a local number but does not say which ones, so you would need to open each plan.

eSIMX also lists limited-time upgrades on two of its voice plans: the 15GB plan is shown with a free upgrade to 35GB, and the 50GB plan with a free upgrade to unlimited data, both until 12/31/2026. Promotions like that can change, so confirm them at checkout.

How the Six Providers Compare Plan by Plan

1. eSIMX: Best for Cheap Short Trips and 30-Day Value

eSIMX lists seven daily plans with 2GB of high-speed data per day: $2.80 for 1 day, $3.80 for 3 days, $4.80 for 5 days, $6.90 for 7 days, $9.80 for 10 days, $14.80 for 15 days and $28.80 for 30 days. The page labels the group unlimited but describes it as 2GB a day, then a minimum of 128 kbps.

The fixed plans are 3GB for 30 days at $3.80, 5GB at $4.80, 10GB for 7 days at $5.80, 10GB for 30 days at $7.80, 20GB for 7 days at $10.80, 20GB for 30 days at $13.80, 30GB for 7 days at $16.80 and 30GB for 30 days at $18.80. The details are on the eSIMX Thailand page.

• Strengths: the lowest listed prices for 3-day and 5-day plans among the six, a 30GB, 30-day plan at about $0.63 per GB, and a 14-day full refund window for an uninstalled eSIM.
• Strengths: the page names AIS, TrueMove H and DTAC, says most plans support multiple carriers you can switch manually, and says most plans support hotspot.
• Watch-outs: some unlimited plans may cap hotspot at 1GB to 5GB a day, and per-plan limits are not listed.
• Watch-outs: top-ups and add-on packs are not supported, so you buy a new eSIM when data runs out, and an installed eSIM is refundable only for a fault on eSIMX’s side or a network issue support cannot fix.
• Watch-outs: the page calls AIS Thailand’s largest network while also saying TrueMove H has the largest combined subscriber base after its DTAC merger, so treat its network claims as marketing.

Activation matters here. The page says to install within 24 hours before departure, and for most plans validity starts when you arrive and connect to a local network. Verdict: my pick for a stay of up to a month if you mostly use maps, messaging and a store dashboard.

2. Nomad: Best for One-Week Unlimited Plans

The Nomad Thailand page lists unlimited plans at 3 days for $9, 5 days for $13, 7 days for $15 and 10 days for $17. The fixed plans are 1GB for 7 days at $5, then 3GB at $6, 5GB at $8 and 10GB at $10, all for 30 days, plus 50GB for 10 days at $15. The page names AIS / True and says the eSIM often comes with more than one local network.

• Strengths: a 7-day unlimited plan at $15 is the second-lowest of the four 7-day unlimited plans listed, and the page says tethering is supported with no caps stated.
• Strengths: you can install now and activate within 60 days of purchase, and add-ons can be bought for some plans and activate when the main plan expires.
• Watch-outs: the 30-day plans stop at 10GB, so the only larger option is the 10-day 50GB plan, and the page does not describe speed caps for the unlimited plans.
• Watch-outs: no refund information or unlock requirement appeared on the page, and the page describes add-ons two ways (simply buy one, versus only some plans have them).

I cover the brand in more depth in my Nomad eSIM review. Verdict: a reasonable fit for a one-week trip when you want an unlimited plan that is cheaper than Airalo or Holafly.

3. eTravelSIM: Best for High-Data Short Stays and Uncapped Hotspot

eTravelSIM lists six data-only plans: 5GB for 7 days at $8.49, 20GB for 7 days at $9.99, unlimited for 7 days at $12.99, 50GB for 10 days at $12.99, 100GB for 10 days at $15.99 and unlimited for 10 days at $15.99. The page names dtac and lists 5G/LTE speed. Details sit on the eTravelSIM Thailand page.

• Strengths: 100GB for 10 days at $15.99 is about $0.16 per GB, and 50GB for 10 days at $12.99 is about $0.26 per GB.
• Strengths: the page allows hotspot on every plan including unlimited, lists fair usage as “None”, and starts validity when the eSIM first connects in Thailand.
• Watch-outs: no 30-day plan was shown, so it does not suit a month-long stay unless you buy twice, and the page says the phone must be factory-unlocked.
• Watch-outs: data only with no number, SMS or talk time, and the refund terms are linked but were not shown.
• Watch-outs: the page contradicts itself on ID, saying no documentation is needed while its FAQ says a passport may be requested for flagged transactions, and the headline says “from $8.49” while page metadata showed $12.99.

Because of those inconsistencies, confirm the price and terms at checkout. I also have an eTravelSIM pricing guide with more on how its prices vary by destination. Verdict: the one to price first for a heavy-data trip of ten days or less.

4. Amigo eSIM: Best for a Simple 20GB, 30-Day Plan

Amigo eSIM lists three Thailand-specific plans: 5GB for 14 days at $9, 10GB for 30 days at $15 and 20GB for 30 days at $20, all labeled data only. A “best value” label appears beside the 20GB plan, the page lists hotspot as unlimited and names AIS GSM and DTAC. You can see the list on the Amigo Thailand page.

The same page also lists Asia and World regional plans, such as Asia 5GB for 30 days at $20 and World 20GB for 30 days at $55. Those are not Thailand-specific, and I do not compare them here.

• Strengths: a short ladder of plans, a 20GB, 30-day plan at about $1.00 per GB, and a statement that the phone must be eSIM compatible and unlocked.
• Watch-outs: the 5GB, 14-day plan works out to $1.80 per GB, and the 10GB plan to $1.50, both well above eSIMX’s fixed plans.
• Watch-outs: a 25GB plan with calls and texts appears in a details section with no price, and the page’s recommender suggests 5GB for 30 days as the best match although no such Thailand plan is listed.
• Watch-outs: it shows a “Money-back Guarantee” heading with no terms, gives two descriptions of when activation happens, and shows a placeholder-looking “text 1” in a network field of the 25GB plan details.

There is also a longer Amigo eSIM review on the site. Verdict: fine if you want a middle-of-the-road 30-day plan from a brand you already know, but its Thailand price per GB is not the lowest.

5. Saily: Best for Small 30-Day Plans and an App Top-Up

The Saily Thailand page lists 1GB for 7 days at $2.99, then 3GB at $5.99, 5GB at $7.99, 10GB at $10.99 and 20GB at $19.99, all for 30 days. The unlimited plan is 15 days at $38.99, described as 5GB a day without a speed limit, then up to 1 Mbps. Every plan lists 3% back in Saily credits.

• Strengths: the 1GB, 7-day plan at $2.99 is the lowest fixed-data price on the six pages, hotspot is listed with no restrictions, and every plan has a 180-day activation period.
• Strengths: top-ups are done in the app, with an automatic top-up option, and SMS and minutes plans are sold separately.
• Watch-outs: its 20GB plan works out to about $1.00 per GB against $0.69 for eSIMX’s 20GB plan, and the 3GB and 5GB plans are about $2.00 and $1.60 per GB.
• Watch-outs: no carrier is named, the refund terms were not described, and the unlimited plan’s 15-day length comes from the plan section because the product card’s duration did not render.

Verdict: worth a look for a short, light trip, or if you want app-based top-ups, but not the lowest price per GB.

6. Holafly: Best for No-Counting Unlimited With a Stated Refund Window

The Holafly Thailand page lists unlimited plans only: 3 days $11.90, 5 days $20.50, 7 days $27.50, 10 days $36.50, 15 days $50.50 and 30 days $73.90. A 1-day option showed as 3.79 euros in the purchase widget, in a different currency from the rest. The page names True / DTAC.

• Strengths: one plan type with no gigabyte math, a spelled-out refund window (requests within 6 months, refunds in 3 to 5 business days, subject to conditions), and an Always On feature giving 1GB of backup data a month.
• Watch-outs: the highest listed unlimited prices among the providers that list a 7-day or 30-day plan, and hotspot sharing equals the plan length in GB, so a 7-day plan shares 7GB.
• Watch-outs: data only, no top-ups, a Fair Usage Policy that can slow speed for up to a day, and two descriptions of when the plan starts.
• Watch-outs: an FAQ says plans run from 1 to 90 days, but only the tiers above were priced, and one FAQ answer showed an unfilled price placeholder.

Verdict: good for a short trip when you do not want to think about data, poor value for laptop tethering or a month-long stay.

Price per GB and Per Day: Worked Examples

Price per gigabyte is the fairest way to compare fixed plans, so here is the arithmetic from the prices above (price divided by gigabytes, rounded to the cent). These are examples based on the listings, not quotes, and prices change. The first table covers 30-day fixed plans only, which is the group where I checked every plan on the six pages.

Shorter plans can be far cheaper per gigabyte, but they cover less time. Here are the fixed plans of 14 days or less that I calculated, so you can see the trade-off.

The lowest figures in that table, about $0.16 per GB, come from two 50GB-or-larger 10-day plans. That figure only helps if you will really use that much data in ten days. Now the daily comparison for plans described as unlimited or daily-capped, using 7 days and 30 days as the common lengths. The eSIMX row is a 2GB daily allowance, not truly unlimited, so it is a different product from the others.

The worked arithmetic for one row: Holafly at 7 days is $27.50 divided by 7, about $3.93 per day, and at 30 days it is $73.90 divided by 30, about $2.46. For a week, the gap between the lowest and highest unlimited plan is $12.99 against $27.50, which is $14.51. For a month, Airalo at $49 is $24.90 below Holafly at $73.90. Whether eSIMX’s $28.80 month fits depends on whether 2GB a day covers you.

Quick Mini-Guide: Which to Pick If…

If you are in Thailand for a long weekend and just need maps and messaging, eSIMX lists the lowest prices among 3-day and 5-day plans, at $3.80 and $4.80. If you are staying a week and want to stop thinking about data, the 7-day unlimited plans run $12.99 at eTravelSIM, $15 at Nomad, $21 at Airalo and $27.50 at Holafly, though the hotspot rules and caps differ, and eSIMX’s 2GB-a-day plan is $6.90.

If you are staying two to four weeks and tether a laptop, a 30-day fixed plan from eSIMX, Amigo eSIM, Nomad or Saily is easier to budget, and the largest ones work out to between about $0.63 and $1.00 per GB. If you want calls, price the eSIMX voice plans first and read the KYC note. If your Thailand trip continues to Japan, my Japan eSIM guide covers that country. For regional and global plans, see my international eSIM guide.

Hotspot, Fair Use and Other Rules to Read Before You Buy

Hotspot is where eSIM listings differ most. The six pages above give six different answers: eSIMX says some unlimited plans cap it, Nomad says tethering is supported with no caps stated, eTravelSIM allows it on every plan, Amigo lists it as unlimited with a linked policy, Saily lists no restrictions and Holafly gives shareable data equal to the plan length in GB.

Activation rules also differ. eSIMX starts validity for most plans when you connect in Thailand, Nomad gives you 60 days to activate, Saily gives 180 days and eTravelSIM starts validity on first connection in Thailand. Install the profile while you still have home Wi-Fi, and only turn on data roaming once you land, since several pages say roaming must be enabled to connect.

Refund wording is thin on most pages. Only eSIMX (14 days if uninstalled) and Holafly (within 6 months) spelled out a request window in what I read. iRoamly lists several conditions and a 3 to 5 business day refund, and the others either linked a policy I could not see or did not show one, so read the terms before paying.

How to Choose Without Overbuying

Start with the days, then the daily behavior. Count the nights you will be in Thailand, then estimate your use: maps and messaging use little, video calls and hotspot use a lot. Pick a fixed plan if your use is lumpy and an unlimited plan if it is steady and you will not tether.

Next, decide whether you need a number or minutes. If the answer is no, any data-only plan works and your home SIM can keep handling incoming calls. If the answer is yes, restrict your list to the eSIMX voice plans and the Saily add-ons, and keep in mind that Thai ID rules are not verified here.

Finally, compare the hotspot rule to your laptop use, check that your phone is unlocked and eSIM-capable, and read the refund and activation lines. My list of the best eSIMs for travel in 2026 covers the wider field. My USA eSIM guide applies the same method to a very different market.

Using a Thailand eSIM When You Run a Store

This is where eSIM choices touch real money. If you run an online business from the road, a dropped connection mid-checkout test or a payment-processor security check can cost you a day. I wrote a separate guide on running an ecommerce business on travel eSIM data, which covers why logging in from a new network can trigger locks. I also keep a list of travel apps worth installing before you fly.

If you are still choosing what to sell, read my explainer on what high-ticket dropshipping is before you go. Then browse the high-ticket niches list to pick a category worth asking suppliers about.

If you plan to meet suppliers in person, my step-by-step supplier guide shows how to prepare for those meetings. The trip itself may also count as a business expense depending on your situation, which is a question for an accountant, not for me. If you are setting up the company side, my guide to business formation for high-ticket dropshipping explains the structures people use. This is general information, not tax or legal advice.

If Thailand is a base for several weeks, I compare long-stay plans in my guide to eSIMs for digital nomads. For the city side of the decision, my Chiang Mai cost-of-living guide breaks down monthly costs.

I do not cover Thai entry rules in this guide. My news post on the visa waiver changes is one place to start. My Thailand DTV guide is another.

If your route runs through Southeast Asia, my Bali cost-of-living guide covers one neighboring base. My Malaysia nomad visa guide covers another.

For a Europe trip, my Italy eSIM guide uses the same format as this one.

Other Providers I Looked At

Airalo’s Thailand page lists plans labeled “UnlimitedGB” only: 3 days $9.50, 5 days $15, 7 days $21, 10 days $31, 15 days $39 and 30 days $49. It names dtac as the primary network plus two others it does not name. Hotspot rules, refund terms and call support were not shown, and the page says top-up packages appear “when available” and its general FAQ mentions auto-renewal when 10% of data remains. The page title says “from $4.00” while the lowest Thailand plan is $9.50, and the $4.00 appears next to a regional Asia link. My Airalo vs Holafly guide compares the two brands further.

iRoamly lists one Thailand plan I could read: unlimited data for 1 day at $2.50, data only, with hotspot allowed and AIS / TRUE named. Its Thailand page contradicted itself on the activation window (60 days from purchase in one place, 30 days from receiving the QR code in another), on speed after the allowance (384 kbps, 5 to 10 Mbps and 5 Mbps in different spots) and on its “from 0.5 USD” headline, so read it closely before buying.

Ubigi has a Thailand entry in its country list, but the Thailand plans and prices did not appear in the content I could load. You can check its data plan list yourself. I would not guess its prices from other destinations.

Mistakes to Avoid With a Thailand eSIM

The first mistake is buying with a locked phone. eSIMX, eTravelSIM and Amigo eSIM say the handset must be unlocked, and Apple says your carrier must unlock the iPhone to use two carriers unless both plans come from the same carrier. Check before you pay.

The second is reading “unlimited” as no limits. In the listings above, unlimited means 2GB a day on eSIMX, 5GB a day on Saily, a 100GB high-speed figure on iRoamly and a fair usage policy on Holafly, while eTravelSIM lists no cap. The third is installing at the wrong time: some plans start the clock when you connect, others when you install, and several pages gave two descriptions, so read the activation line.

The fourth is assuming data includes a phone number. Most plans here are data only, so plan for messaging apps or choose a voice plan on purpose. The fifth is buying a 7-day or 10-day plan for a longer stay. Several of the cheapest per-GB plans in this guide are short ones, and eTravelSIM shows no 30-day plan at all, so check the validity column before you chase a low price per GB.

The sixth is trusting a single page. Several pages in this guide disagreed with themselves, including eTravelSIM’s ID wording, Amigo eSIM’s “best match” for a plan it does not list and Holafly’s unfilled price placeholder, so confirm the plan name, network and price at checkout.

Frequently Asked Questions

What is the best eSIM for Thailand?
It depends on your trip, and this is my opinion based on published pages, not testing. For the lowest 30-day price per GB I would look at eSIMX, for a big short-stay plan at eTravelSIM, and for a one-week unlimited plan at Nomad or eTravelSIM.

Can I get a phone number or calls with a Thailand travel eSIM?
Only some plans. eSIMX lists three call or SMS plans, with outgoing calls and SMS on its 8-day plan needing KYC at a TRUE store. Amigo eSIM shows a 25GB plan with calls and texts but no price, Saily sells texts and minutes separately, and eTravelSIM and Holafly are data only.

Is an unlimited Thailand eSIM really unlimited?
Usually not in the plain sense. The pages describe a daily high-speed allowance (2GB on eSIMX, 5GB on Saily), a high-speed figure of 100GB on iRoamly or a fair usage policy on Holafly. eTravelSIM’s page lists fair usage as “None”, so confirm that at checkout.

Which iPhones work with a Thailand eSIM?
Apple lists the iPhone XS, XS Max, XR or later as supporting eSIM, and to use two carriers your carrier must unlock the iPhone unless both plans come from the same carrier. For Android, check compatibility on the provider’s page.

Do I need to register an ID for a Thailand eSIM?
I could not verify Thai rules from an official page, so I cannot say. Vendor pages differ: eSIMX mentions KYC at a TRUE store for outgoing calls and SMS on one plan, iRoamly lists ID verification, and eTravelSIM says a passport may be requested if a payment is flagged. Check at checkout, and the Amigo eSIM page showed no ID requirement in what I read.

This is general information, not financial or legal advice. Plans, prices and terms change often, and I have not tested these eSIMs, so check each provider’s page before you buy. Prices above are as of November 2026.
