Best eSIM for Thailand
Ryvo is ours, which makes this page an argument and not a review.
The rules sit above the ranking, every rival number links to the page it was read on, and three of the four picks below go to sellers who are not us.
The best eSIM for Thailand is the one that tells you how much data you get before you pay.
Our Thailand plans print the total, the days and the price per day on the card.
Not one of the three sellers below published a data total on the day we looked.
Every figure carries its page and its date.

Rows marked We make Ryvo come from our own plan data. Prices stay in the currency each provider published. Each date is the day we read that page.
Who should pick which
You are in Thailand for a week or two and roughly know how much data you get through at home
Pick: Ryvo
Pick a size, and the card states that size, the days it runs and what each of those days costs, in Australian dollars.
Not one rival in this table published a data total, and not one of them quoted us Australian dollars.
You are staying a month and would rather not count gigabytes at all
Pick: Airalo
Airalo names the amount you get each day at full speed, the speed it drops to afterwards and when the day restarts, which no other seller here does.
It also says it caps nothing on tethering, and its thirty-day total sits well under Holafly's, the only other thirty-day plan in the table.
You are travelling with someone who will run their phone off yours
Pick: Holafly
Holafly is the only seller here that puts a figure on how much you may share each day and says how that figure grows with the length of the plan.
You may not like the figure, but you can read it before you pay.
You want to be able to add data to the same eSIM months later
Pick: Simify
Simify is the only seller here that puts a window on it, and says topping up is done in its own app.
Its ten-day plan is the dearest per day in this table, which is the trade.

How we compared
What each rule checks
- Does it tell you where the line is. A plan sold with no total still slows down somewhere. A seller that names the amount you get each day at full speed and the speed it drops to afterwards ranks above one that leaves both to a help page.
- Does it fit a long weekend or a month. The two Thailand trips we see are a week or ten days split between Bangkok and an island, and a month or more for people working from Chiang Mai or Koh Phangan. A plan sold only in one of those shapes is ranked for that shape.
- What the trip costs, over its own length. The seller's own total for the plan's own days, plus that total divided by those days. Every price here was served to us in US dollars, so the table says so rather than converting anything.
- Can a laptop use it, and can you add more. Two questions one column apart. Whether the connection reaches a second device without a cap of its own, and whether an eSIM already installed can take more data later instead of being replaced by a new one.
- Did the seller publish it at all. Anything we could not read on the seller's own page is missing from this table on purpose. An empty cell tells you something. A filled one we could not stand behind would tell you the wrong thing.
How this page is built
Nobody types a Ryvo figure into this page. Our sizes, days and prices are read when the page renders from the records that build our Thailand page and charge our checkout, so the till cannot disagree with the table, and a plan we withdraw loses its row instead of going stale inside it.
A rival row is that seller's own sentence, with the link beside it and the day somebody opened it. Nothing is trimmed into meaning less than it says. Where a page answered a question with silence, the cell reports the silence. We review nobody, ourselves least of all.
Prices stay in the currency each seller showed us on the day. All three quoted us US dollars for Thailand, so no rival total in this table can be read straight against ours, which are in Australian dollars. A seller can serve a different currency on a different day, which is one reason every row carries its own date.
Our own Thailand prices are set against Airalo, at about two Australian dollars under its price for the same destination. This table cannot show that, because what Airalo published to us was in US dollars and we do not put a conversion rate of our own on the page.
Two absences are on purpose. Airalo and Simify each offer a fixed-data filter on their Thailand pages and neither handed us a fixed-total plan, so no rival row here carries a total. And Simify showed us one length only, the one it pre-selects, so its other lengths are absent rather than estimated.
Per day is the published total divided by the plan's own days, rounded to the nearest cent. Prices stay in the currency each provider published, because a rate we picked on the day is not a price anyone published.

Questions about this comparison
How much does an eSIM for Thailand cost?
Our own sizes and prices are in the table above, read when this page renders from the records the checkout charges from, so the till cannot disagree with them.
The three sellers below publish their own totals in US dollars, each with the link and the day somebody read it beside the figure.
How much data should I buy for Thailand?
For a week split between Bangkok and an island, a mid-sized total covers maps, Grab, LINE and a normal amount of scrolling.
For a month, go a size up rather than hoping.
Our Thailand page turns each total into hours of maps, messaging and video so you can judge it before paying.
Will any of these work on the islands?
All of them run on Thai networks, and those thin out on the quiet corners of Phuket, Samui and Koh Tao and on the water between them.
That is a network fact rather than a plan fact, so it is the same whichever row you buy.
What does Not published mean in the cap column?
That the seller does not say.
Every rival plan here is sold without a total, and a plan without a total slows somewhere.
Two of the three name the amount and the speed.
Where a page names neither, we report that instead of estimating it.
Why are none of the rival prices in Australian dollars?
Because that is what the three sites served us.
We print what was printed.
A conversion of ours would be the one figure on this page nobody else could look up and check, which is exactly the figure we do not want here.
Will Grab work on any of these?
All of them carry mobile data, which is all Grab needs to book a car or a bike, watch the driver arrive and pay in the app.
Set the account up at home, because the sign-up sends a code to your number.
Do I set it up before I fly?
Yes, on Wi-Fi at home.
Setting one up takes a connection, and the queue at Suvarnabhumi is the wrong moment to discover that.
Where a plan starts on its first connection abroad, doing it early costs you no days at all.
Will my Australian number still work?
Yes, on every plan here.
These are data plans, so nothing comes out of your phone.
Your own SIM keeps the calls, the texts and the codes your bank sends, and the eSIM takes the data off it.
How old are these figures?
Each one carries the day it was read, in its own cell.
Our build stops once any of them turns three months old, so what you see is either recent or already queued for a re-read, and the link beside it goes to the seller.
In short
For a week or two in Thailand, Ryvo is the pick: a total you chose, with the days and the price per day beside it.
Airalo is the one to buy for a month without counting gigabytes, because it names the daily amount and the speed after it.
Holafly spells out how much you can share, and Simify puts a window on topping the same eSIM up later.
