eSIMratCompareeSIM promo codes: the verified discounts for August 2026
An eSIM promo code cuts the price of your travel data plan by 5 to 30% on a single line at checkout. Finding one is not the problem: coupon sites list hundreds. The problem is that a good half of them no longer work.
Here you will only find the active promo codes of the providers we compare, and therefore the best deals actually available, not a stale bargain copied from somewhere else. Each one is tested on a real order before it lands in the table, with its verification date shown beside it. A dead code is removed, not left online with an “unlimited” label that means nothing.
One partner for now, so one code: that one works. The list grows with every provider we sign, and every row added goes through the same verification.
How do you use an eSIM promo code?
Entering the code takes two minutes. The process is the same at every provider, whether you go through the website or the mobile app.
Compare the plans and click “See the offer”.
Pick your destination, your data volume and your duration.
At checkout, look for the “Promo code” field.
Paste the code and check the total drops.
Pay, get your QR code and install the eSIM in 5 min.
Step 1 : start with our eSIM comparator to find the best plan for your destination. You compare 205 destinations and more than 1,100 plans ranked by price per GB. Then click “See the offer” to land on the provider's site.
Step 2 : on the provider's site, choose the data volume (1 GB, 5 GB, 10 GB, unlimited data depending on the offers) and the validity period (7, 15, 30 days). Add the eSIM plan to your basket.
Step 3 : find the “Promo code” or “Discount code” field on the order page. Paste the code copied from our table and confirm. Watch out for spaces before or after: that is the number one cause of codes that seem not to work.
Step 4 : the order total should drop immediately, by the stated amount. If nothing moves, do not pay: the code may be restricted to a first purchase, to new customers, or to certain destinations.
Step 5 : once payment goes through, you receive your eSIM by email or in the app, as a QR code. Installing it is simple and takes under five minutes. You can activate the code, then your plan, on arrival abroad: activation is a single step and your phone connects automatically to the local partner network.
Where to find eSIM promo codes (and which to ignore)
Not all codes are equal, and above all, not all sources are equal. Here is where eSIM promo codes circulate, from the most reliable to the most useless.
Partner comparators
A comparator that has signed with a provider negotiates an exclusive code and earns a commission on sales. So it has every interest in the code working. That is our case, and it is the most reliable source, provided it shows a verification date.
The provider's own site
Airalo, Holafly, Saily, Nomad, Yesim, Ubigi and voilà show their current promotions directly on their website or in their newsletter. It is reliable, but rarely the best discounts: partner codes often do better.
Referral codes
Most providers give a €3 to €5 credit to both the referrer and the referee. If a friend already uses a travel eSIM, ask for their code before buying. The credit often stacks with a regular promo code.
General coupon sites
They aggregate codes found elsewhere, without ever testing them. You will find 120 rows there, half of them dead for six months, each labelled “valid”. It is the most abundant and the least reliable source.
Airalo, Holafly, Saily, Nomad, Yesim and Ubigi promo codes: coming to the table
If you are looking for an Airalo promo code, a Holafly promo code, a Saily discount, a Nomad offer, a Yesim code or a Ubigi code, they are not in our table yet. We are in the process of signing partnerships with each of these providers.
We only publish a code once the partnership is signed and the code has been tested on a real order. Copying a code found elsewhere means risking sending you to an expired one with no way to verify it. We would rather have a short, reliable table that we extend every month.
Every provider we add arrives with its exclusive code, its detailed review page and its integration into our comparator. If you want to know when a new code lands, come back to this page: it is updated with every signature.
Our verification rules
Three rules, applied to every code, at every update.
Tested on a real order
Every code is entered in a real basket right up to the payment screen. If it does not bring the total down, it does not ship.
Dated, not “unlimited”
The “Verified” column shows the date of our last test. It is the only verifiable piece of information about a promo code.
Transparent about the commission
We earn a commission on purchases made through our links. It funds the testing; it changes neither your price nor the order of the table.
How much a promo code really saves you
A discount percentage means nothing until it is applied to a price. Run the numbers on your own trip.
The RAT simulator
An estimate based on a standard eSIM plan. The real price depends on the destination and the provider.
The only active partner for now
Average price: €0.63/Go
A −5% code on a well-chosen plan beats a −20% code on an overpriced one. The real lever is still the price per GB: compare first, apply the code after.
Six ways to save more on your eSIM plan
The promo code is the last lever, not the first. Here are the other five, from the most rewarding to the least obvious.
Compare on price per GB, not the sticker price
A €5 plan for 1 GB costs €5 per GB. A €12 plan for 5 GB costs €2.40. The second is half the price despite the higher sticker. Our comparator ranks everything on that metric.
Do not oversize your data
For a typical trip (maps, messaging, a few searches), 1 GB a week is plenty. If you tether or watch video, aim for 5 to 10 GB. Paying for 20 GB and using 3 wipes out any discount.
Use a referral code on top of the promo code
Referral credit (€3 to €5 typically) often stacks with a regular promo code, unlike two promo codes together. Ask a friend who is already a customer for their code before your first purchase.
Target the promotion periods
Black Friday, Cyber Monday, summer sales: providers put out 30 to 50% discounts, well beyond permanent codes. They rarely stack with a code, but they are often more generous.
Buy ahead, activate on arrival
Most eSIM plans start on first connection to the network, not at purchase. So you can buy during a promotion weeks before you leave and activate on the day, without losing a single day of validity.
Take a regional plan if you move around
For a tour of Europe, or a Thailand-Vietnam-Cambodia itinerary, a regional plan works out 30 to 50% cheaper than several country plans in a row, and saves reinstalling an eSIM at every border. Apply the code on top.
The 2026 eSIM promotion calendar
If your departure is flexible, these periods beat any permanent code.
Why an eSIM works out cheaper than a physical SIM
Even before the promo code, choosing an eSIM is already a saving compared with the two classic alternatives abroad.
Against your carrier's roaming, the gap is brutal outside the Europe zone. A French mobile plan bills out-of-bundle data at several euros per megabyte in the United States or Asia. A local eSIM plan costs a few euros for several gigabytes. Same service, same masts.
Against a physical SIM bought locally, an eSIM saves you the airport shop, the queue, the ID to show, and the risk of losing your home SIM during the trip. You install your eSIM profile before you leave, activate it on arrival, and your usual number stays active for calls and texts.
An eSIM is a digital product: no stock, no logistics, no manufacturing costs. That is also why providers can afford permanent 5 to 20% discounts without cutting back on network quality.
Is your phone eSIM compatible?
A promo code is no use if your phone cannot install the profile. Check before you buy: most smartphones released after 2019 are compatible.

One more condition, often forgotten: your phone must be carrier-unlocked. If it is locked to an operator, it will refuse another network's eSIM profile, promo code or not.
Which eSIM plans can you pay for with a promo code?
A partner promo code generally applies to the provider's whole catalogue. Here are the four plan families you will come across.
Country plan
One destination, from 1 to 50 GB, valid for 7 to 30 days. The most common and the cheapest per GB. At voilà, prices start at €0.80 per GB depending on the destination.
Regional plan
Europe, Asia, Latin America: a single eSIM valid across several countries. Ideal for a multi-destination itinerary, pricier per GB than a single country plan but far cheaper than stacking several.
Global plan
A hundred or so countries on one eSIM. The most expensive per GB, meant for very mobile travellers or professionals hopping between continents.
Unlimited data
Sold by some providers, almost always with reduced speed after a daily allowance. Useful for a long stay, worth comparing against a large standard plan before deciding.
All our eSIM providers
Every partner has its review page: real price per GB, coverage, network quality, app, customer service. We test before we sign.
Frequently asked questions
Yes. Every code is entered in a real basket right up to the payment screen before publication, and the date of that test is shown in the “Verified” column. If a code stops working, it is removed from the table, not kept with an “unlimited” label.
No. eSIM providers accept only one discount code per order. Take the one with the biggest discount: the table is already sorted that way. A promo code does often stack with referral credit, a running offer on the provider's site, or cashback from a browser extension: those three do not go through the same field at checkout.
Some do, others are permanent for as long as the partnership lasts. Codes marked “Unlimited” in the Validity column have no end date announced by the provider, which does not guarantee they will still work in six months. That is exactly why we show the date of our last verification beside them: it is the only genuinely verifiable information about a promo code.
Three checks, in order. First, make sure no space slipped in before or after the code when you pasted it: that is the most common case. Then respect the capitals. Finally, check the conditions: some codes are restricted to a first purchase, to new customers, or to certain destinations. If the code still refuses to apply, contact the provider's customer service, usually reachable by chat or WhatsApp. And tell us: we remove dead codes the same day.
Yes, and they vary from provider to provider: minimum order value, eligible destinations, new customers only, not combinable with a running promotion, limited validity. These conditions are shown on the provider's site at the time of order.
Yes, in almost every case. The process is identical to the website: you copy the code, paste it into the field at the payment step, confirm, and check the total has dropped. One detail to watch: if you buy from the app, the tracking link from our site may not be preserved. The code will still work.
No. The discount applies at payment, never retroactively. Once the order is confirmed, no provider will refund the difference. If you notice immediately and the eSIM is not yet activated, contact customer service: some will cancel the order so you can place it again with the code.
No. The code acts on the price, not on the service. Your eSIM connects to the same local operator masts, with the same speed and the same 4G or 5G coverage, whether you paid full price or with a discount.
Because we only publish codes negotiated directly with providers we have tested and integrated into our comparator. A list of 120 codes copied from elsewhere, half of them dead, inflates a page but not your savings. Our table grows as we sign new partners, and every row added goes through the same verification.
By combining the two levers in the right order. First the plan: go through the comparator and take the one ranked best on price per GB for your destination, with the right data volume. Then the code: apply it to that already-optimised plan. A 5% discount on a well-chosen plan beats a 20% discount on an overpriced one. The code is the last step, not the first.
The code is the cherry on top
First compare 1,152 eSIM plans across 205 destinations, on price per GB. Apply your code after.
