How to use the Saily eSIM promo code
Three steps, at payment time. The good news: at Saily the promo code field is reachable without creating an account, right on the checkout screen.
- 1Pick your planVolume and duration are chosen before the basket, and that choice weighs most on the bill.
- 2Open the promo code fieldOn the checkout screen, unfold the “Have a promo code?” row. No account is required to get there.
- 3Apply and check the totalType ESIMRAT. The discount line joins the summary and the total recomputes on screen.
The rat's advice: check the total BEFORE paying, never after. A settled order cannot be fixed, and support will not apply the discount retroactively. And do not try to stack two: as soon as a code is applied Saily locks the field, and you have to hit “Remove” to test another one.
The Saily promo code that works in September 2026
A single code, and we added it to the cart on September 22, 2026, twice: on the 20 GB Japan plan at €21.99, reduced to €19.79, and on the 15-day unlimited plan at €43.49, reduced to €39.14. ESIMRAT takes 10% off any order, whether it's your first or not, without needing to create an account.
The second code in the table is for demonstration purposes: SAILY50, copied from an aggregator, was rejected by the cart with the message "This promo code is not valid." The 20%, 25%, or 50% discounts promised in the headlines of these sites do not exist at Saily: at the time of payment, only one code actually works.

ESIMRATeSIMrat code, any order-10%SAILY50Seen on aggregatorsRejectedTest conducted on the 15-day unlimited Japan plan for €43.49, without an account and without paying. A code rejected by the cart is indicated as such: it is the only proof that matters.
The code is applied after choosing the plan, never before: it's the data volume that determines the bill, and the discount is added on top. And once ESIMRAT is registered, Saily displays its entire price list with strike-throughs and a "Save 10%" badge, allowing you to compare plans with the discount included.
The Saily promo code, tested in a real basket
We did not copy the code off another site. On 22 September 2026 we opened Saily's Japan page, picked the 20 GB / 30 day plan, and went through to the checkout screen, no account, nothing paid.
The discount field unfolds by clicking “Have a promo code?”, under the order summary. Code typed, Apply pressed, and a Promo code ESIMRAT line appears with a -$2.50. The $24.99 subtotal drops to $22.49.
Once the code is registered, Saily keeps it for the session: go back to the pricing grid and every plan shows struck through with a “Save 10%” pill. Handy for comparing, and it confirms the discount does not depend on the destination.
A detail nobody mentions: Saily credits, the 3% paid back on every purchase, are computed on the discounted amount, not on the sticker price. On this basket the credit lands at $0.67, three per cent of the $22.49 you actually pay. You give up a few cents of credit to save $2.50 straight away, so the maths stays overwhelmingly in your favour, but it is worth knowing.
Take the test for what it is: a dated measurement. A provider can switch a code off overnight without telling anyone. The date sits on this page so you know how recent the last check is, and we re-run it regularly.
What 10% actually saves you
A percentage discount pays in proportion to the price. Here is what 10% means on Saily's Japan grid, read on 22 September 2026, from 1 GB up to unlimited.
1 GB over 7 days at $3.99: you save 40 cents. 5 GB over 30 days at $10.99: $1.10. 20 GB over 30 days at $24.99: $2.50. Unlimited over 15 days at $48.99: $4.90.
Prices read on saily.com on 22 September 2026, Japan page in dollars. Saily also quotes in euros, pounds and Swiss francs: the currency is picked in the site header and changes the amounts.
The reading is always the same: on a small plan the discount is worth less than a coffee. It becomes a real argument on large volumes and on unlimited. And the plan you pick weighs ten times more than the code: paying for 20 GB when 5 would do costs $14 too much, five times what the discount returns. Our data calculator answers that question before the code matters at all.
What 10% saves, Saily's Japan grid on 22 September 2026
Prices read on saily.com in dollars. The discount follows the price: the smaller the plan, the more symbolic it gets.
The code or the right plan: where the real saving is
This is the arbitration that matters, and it has nothing to do with the code. On Saily's Japan grid the 20 GB plan costs $24.99 and the 5 GB one $10.99. A traveller who takes 20 GB when 5 would do pays $14.00 too much.
Side by side, on the same grid read on 22 September 2026, it looks like this.

Sizing weighs five times more than the discount. The two stack, of course: the right plan, then the code on top. But if you only check one thing before paying, check the volume, not the code.
The code is still worth taking: it is free and it applies in three clicks. But sizing the plan right pays five times more, and it is the only decision made before the basket. Our data calculator gives you the order of magnitude in thirty seconds.
Fake Saily promo codes and how to spot them
On this query, dozens of sites list codes like SAILY50, WELCOME30 or FREEDATA, often presented as massive discounts. Saily is one of the most heavily sponsored eSIM brands on the market, so also one of the most flooded with fake lists.
The mechanism is always the same: the site publishes a long list to catch the click, betting you will try its affiliate code anyway, the only valid one. A 50% discount on an eSIM does not exist: the sector's margins do not allow it.
Three reflexes are enough. One, distrust any eSIM discount above 20%. Two, check the last test date shown, and walk away from pages that give none. Three, test the code in the basket before paying: it is the only judge, and at Saily it costs three clicks since no account is asked for.
Our eSIM promo codes page applies that rule to every provider compared, with the verification date where one exists. And to place Saily against the rest, price per gigabyte in hand, there is the eSIM providers page.

Frequently asked questions
The ESIMRAT code gives 10% off a Saily eSIM order. It was tested in a real basket on 22 September 2026: a 20 GB Japan plan at $24.99 came to $22.49, a $2.50 discount, with no account needed to apply it.
On this page, tested in a real basket, with the test date shown. Be wary of aggregators listing ten codes with no verification date: most no longer work, and the only valid one in the list is their affiliate code.
10% of the order. On Saily's Japan grid read on 22 September 2026, that runs from 40 cents on a 1 GB plan to $4.90 on the 15-day unlimited. On the 20 GB plan at $24.99, the discount is $2.50.
Yes. On the Japan grid read on 22 September 2026, the 15-day unlimited goes from $48.99 to $44.09, a $4.90 discount: it is the plan the 10% pays most on. The “Save 10%” pill shows on every unlimited duration, from 5 to 30 days.
Three common causes. Another code is already applied: Saily locks the field until you press “Remove”, and two codes never stack. The code is limited to new customers and your account has already ordered. Or it has simply been switched off, which happens without notice. Always test the code before paying.
Yes. The discount is a percentage applied to the order amount, whatever the destination. Once the code is registered, Saily even shows its whole grid discounted, with a “Save 10%” pill on every plan.
No, and it trims them slightly. Saily credits, the 3% paid back on every purchase, are computed on the discounted amount: on the basket we tested the credit comes to $0.67, three per cent of the $22.49 paid rather than of the $24.99 sticker. You give up a few cents of credit for $2.50 off straight away, so the maths stays clearly in your favour.
We rated Saily criterion by criterion in our full review: price, coverage, installation, app and support. In short, a solid brand backed by Nord Security (NordVPN), 200+ destinations and a very well rated app, but a price per gigabyte that is rarely the market's best, discount included.
Here: ESIMRAT, added to cart on September 22, 2026, for two Japan plans, €21.99 reduced to €19.79 and €43.49 reduced to €39.14. It applies without an account, to all destinations, and on all orders, not just the first one.
No. Aggregators that display 20%, 25%, or 50% in their titles do not keep their promise: the code SAILY50 found on one of them was rejected at checkout on September 22, 2026. The only code we saw pass through that day was ESIMRAT, at 10%.
Yes. Saily is published by Nord Security, the company behind NordVPN, and shows a rating of 4.7 out of 5 from over 97,400 reviews on its website as of September 22, 2026. In our review, it scores 4.5 out of 5: solid installation, app, and support, though the price per gigabyte is rarely the lowest.
