Saily's own coupon page publishes no coupon

The short answer

There is no public Saily coupon code, and the strongest evidence for that is Saily's own.

Saily runs a coupon page at saily.com/coupon/, titled "Valid Saily eSIM coupon code – August 2026". It explains how to redeem a code — open the checkout, click "Got a coupon?", paste it in, press Apply — and it carries a Get the Discount button. What it does not carry, anywhere in its text, is a code. We read it on 17 August 2026.

That is worth sitting with. The company has built and kept up a page aimed at the exact search you just ran, and still declines to name a code on it. If Saily will not publish one there, the strings on aggregator sites are not coming from Saily.

So we will not print one either — not a code lifted from somewhere else, not an example, not a placeholder. A code that fails at checkout costs you the two minutes you spent finding it and the trust you extended to whoever gave it to you.

What Saily actually runs

Three programmes are real, and none of them is a code you can look up.

A referral. US$5 in Saily credit to the person referring, US$5 off for the friend. It works through a link tied to an existing account, not through anything typed at checkout. Five dollars is a bigger discount than most circulating codes even claim — on a $10.99 plan it is a 45% cut — but it needs someone who already has an account.

A student discount run through StudentBeans, at saily.com/special/studentbeans/. Verification happens on the StudentBeans side. We have confirmed the programme exists; we have not tested the amount.

A nonprofit programme at saily.com/nonprofit/, which works by application rather than by code.

By Saily's own account there is a "Got a coupon?" field waiting at checkout, and that field is why the aggregator pages look plausible: somewhere to paste implies something to paste. On the evidence of the page describing it, there is nothing to put in it.

The saving that beats any coupon

Saily's ladder has the same shape in every country we have checked: 1 GB for 7 days, then 3, 5, 10 and 20 GB over 30 days. In all twenty countries we verified, the 20 GB plan is the cheapest per gigabyte and the 1 GB plan the dearest — and the gap between them is far wider than any discount code would be.

Thailand, read off the checkout on 13 August 2026:

Top to bottom, that is a threefold difference in what a gigabyte costs. A 10% code applied to the wrong rung would still leave you paying nearly three times the rate of the right one.

The middle of the ladder matters too. Two 5 GB plans cost $15.98 for the same allowance as a single 10 GB plan at $10.99 — buying the smaller one twice costs $4.99 more for exactly the same data. If you are between sizes, the larger plan is almost always the cheaper mistake.

And watch the durations. Everything above the entry plan runs 30 days; the 1 GB plan runs 7. It is the cheapest line on the page and the one most likely to expire mid-trip.

Prices move, in both directions

Until this month's price check, our own dataset held Saily's 1 GB plan at exactly $3.99 in every country it covered. Read at source it runs from $1.99 in Austria and the Czech Republic to $8.99 in Egypt and Morocco, so the flat figure was invented rather than gathered — and picking the right country is worth more than any coupon would be. Flat everywhere should have been the tell.

Reading twenty checkouts produced a range instead: $2.99 in Thailand, $3.99 in thirteen markets, $4.49 in Germany, Greece and the UK, $4.79 in Indonesia, $4.99 in Mexico and $5.29 in Canada. Where we held an old figure and a new one, it moved both ways — down in Thailand, up in Germany, Indonesia, Mexico and Canada. That is what live pricing looks like, and no code produces it.

The spread between countries is larger again. The same 20 GB plan over 30 days is $19.99 in Thailand and $43.99 in Canada. Nothing you paste into a coupon box moves a number by that much.

What we have actually checked

We hold 225 Saily rows across 48 countries. One hundred and eighty-five of them, covering 37 countries, were read off Saily's own checkout on 13, 16 and 18 August 2026: Australia, Austria, Belgium, Brazil, Canada, Croatia, the Czech Republic, Denmark, Egypt, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Italy, Japan, Mexico, Morocco, the Netherlands, Norway, the Philippines, Poland, Portugal, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Thailand, Turkey, the UK, the USA and Vietnam.

The two dates cover different countries — none was read twice — so we cannot tell you how often Saily reprices. What we can say is that in the twelve countries where we had an old figure to compare against, six of them had moved. A price copied out of an article written months ago, ours included, is a coin toss.

The other 28 countries are indicative — extracted from older text, not read from a checkout — and we label them that way rather than dressing them up. There is one further gap worth naming: our reads captured metered plans only, so where Saily sells an unlimited plan we hold no verified price for it.

What to do instead of hunting a code

Use the plan finder on this page: destination, trip length, rough data need, and it does the arithmetic across every provider we hold — including whether a local SIM beats the eSIM outright. Then check the cheapest verified plans, the Saily provider page for how it compares against the rest, and how we test for what our labels mean.

The honest version of this page is short: there is no code, the price on the page is the price, and the money is in picking the right rung.
