Sim Local Coupon ESIMDISCOUNT10 is a 10% discount code for Sim Local, the Dublin-based travel SIM and eSIM retailer. Entered at the online checkout, it reduces the order total by a flat tenth, meaning you pay 90% of whatever the plan is listed at. There is no tiering, no scaling with basket size and no separate reward step — it is a single string, applied once, and the total drops.
"Coupon" here means a checkout code, nothing more
The word coupon carries some baggage. In everyday use it suggests a one-off, paper-style offer — something clipped, printed or handed over, valid for a single use at a single till. A voucher, by contrast, usually implies stored value: a balance you draw down. A discount code is simply a string typed into a field.
At Sim Local, all three words describe the same single mechanism. ESIMDISCOUNT10 is not a paper coupon, it does not carry a balance, and it is not redeemed at a counter. It is a code you type into the order form on the website before you pay, and the displayed total falls by 10%. If you have searched for a Sim Local coupon, a Sim Local voucher or a Sim Local discount code, you are looking for the same thing. There is no separate coupon scheme to hunt for, and no printable version to bring with you.
This matters practically for one reason in particular, covered below: Sim Local is unusual among eSIM sellers in having a physical retail presence, and a checkout code belongs to the online checkout only.
Who Sim Local is
Sim Local was founded in 2011 by the Irish entrepreneur Killian Whelan. The company is headquartered in Dublin with an office in London, and describes itself as "the global leader in Travel SIM card and eSIM Retail" — that is the company's own framing rather than an independent assessment. Its eSIM operation runs at an eSIM sub-site under the same brand and the same company.
The business is a retailer rather than a network operator. Rather than running its own towers, it sells plans from established operators, and its about page names EE, Orange, Lycamobile, Three, AU in Japan, True, Digicel and Mobifone among them. Practically, that means the connection you get is a real carrier's network, resold through Sim Local's storefront and delivered as an eSIM profile.
On scale, the company says it has connected millions of customers since 2011; a third-party company profile puts the headcount at roughly 73 employees across three continents as of February 2026 and cites four million customers. Apps are available on both iOS and Android.
The airport catch worth knowing first
Sim Local is not only an online store. It sells travel SIMs and eSIMs through airport shops, kiosks and vending machines, and the airport locations named on its site include Dublin, London Heathrow, London Gatwick, Brussels, Athens, Madrid and Copenhagen, alongside US airport partnerships. An exclusive UK airport distribution partnership with WHSmith Travel dates from 2017.
That physical footprint is genuinely useful if you have forgotten to sort connectivity before flying. It is also the single biggest trap around this code. A checkout coupon cannot be applied at a vending machine or handed to staff at a kiosk — there is no field to type it into. If you first encountered the brand at an airport and want the 10% off, you need to buy through the website or the app instead. Buying in person and asking afterwards is not a route to the discount.
What 10% off actually saves you
Because the rate is flat, the arithmetic is simple: multiply by 0.9, or work out a tenth and subtract it. On the global eSIM plans listed on the research date, in US dollars, the prices were:
100GB, 116 countries, 31 days — $93.50, so about $84.15 after 10%
50GB, 117 countries, 31 days — $70.25, so about $63.23 after 10%
30GB, 71 countries, 30 days — $47.00, so $42.30 after 10%
20GB, 72 countries, 31 days — $35.00, so $31.50 after 10%
12GB, 71 countries, 30 days — $20.00, so $18.00 after 10%
3GB, 109 countries, 31 days — $10.50, so $9.45 after 10%
Those were the global plans at the time of research, and prices for any product can move, so treat the figures as a guide to the shape of the saving rather than a live price list. The pattern is the important part: a percentage discount is worth more in absolute terms on a larger plan. On the smallest global bundle the saving is small change; on the largest it is a meaningful single-figure-percentage cut of a near-$100 purchase. If you are choosing between two plan sizes on price alone, apply the 10% to each before comparing, because the gap narrows slightly.
A coverage quirk worth checking before you buy
Look again at the country counts in that list. The 50GB plan covered 117 countries and the 100GB plan 116, but the 30GB and 12GB plans covered 71 and the 20GB plan 72 — while the smallest plan, 3GB, covered 109. In other words, buying more data does not automatically buy you broader coverage. The bundles are built differently, and the country list is a separate attribute from the allowance.
So the order of operations matters. Confirm your destination is on the plan's country list first, then pick the data size, then apply the coupon. Choosing on price or gigabytes alone risks landing on a plan that happens not to include the place you are going.
On overall reach, the company advertises more than 150 countries and regions, while its about page refers to plans from over 100 countries. Those are the company's own claims. Alongside the global plans there are local and regional options; their prices are not covered here, and neither is any confirmation of whether the coupon applies to them.
How to apply the code
The exact position of the discount field is not something to state precisely — online checkouts differ and get redesigned. The general shape is consistent enough to work from, though:
Pick your destination or the global plan and check the country list covers where you are travelling.
Choose the data size and duration that fits the trip, and note the listed price before any discount.
Go to the checkout or cart and look for a field labelled something like promo code, coupon, voucher or discount.
Enter ESIMDISCOUNT10 exactly as written, with no spaces, and confirm it.
Check the total has fallen by a tenth before you enter payment details. A 10% reduction should leave you paying 90% of the listed price.
Only then complete payment.
The fifth step is the one people skip. A code that has not registered will not be honoured retroactively just because you typed it somewhere, so treat a visibly reduced total as the only confirmation that counts. If the field is collapsed behind a link, it is usually near the order summary rather than in the personal-details section.
What the plans deliver
Activation happens within minutes, either through the app or by following instructions sent by email, and there is no physical SIM to swap — which is the main practical advantage of an eSIM over a traditional travel SIM. Networks are 4G, 5G or 3G depending on the plan and the local operator.
Some plans include calls and SMS while others are data-only, with calls and texts described as available in popular destinations. If voice matters for your trip, check the specific plan page rather than assuming. Sim Local also advertises up to 10GB of full-speed data daily without throttling on its plans, contrasting this with providers that slow down after smaller daily amounts — that is the company's own claim and it is not a claim of unlimited data.
Refunds and the unknowns
The site advertises a "No Quibble Refunds" guarantee, framed as getting your money back if you change your mind. That is a genuinely reassuring headline for a product you are buying before you travel, but the conditions — anything about activated versus unused profiles, or time limits — are set out on the policy page, and that is where to read them before relying on it.
There are also things this code does not tell you. Whether ESIMDISCOUNT10 covers every product, including local and regional plans or physical SIMs bought online, is not stated. Neither is whether it works in the app as well as on the website, nor whether any minimum spend, expiry, per-customer limit or first-order-only condition applies. Hotspot and tethering support is likewise not covered. None of those gaps is a reason to avoid the code; they are reasons to try it at checkout and read what the checkout tells you rather than assuming.
Honest verdict
A flat 10% off is a modest but clean offer. There is nothing to earn, refer or accumulate, and nothing conditional to keep track of — you type a string and pay a tenth less. That suits the reader who has already decided a travel eSIM makes sense and simply wants the listed price trimmed.
It suits three groups in particular: buyers going for a larger plan, where 10% is worth the most in cash terms; travellers who prefer buying from an established retailer that resells recognisable operators' plans rather than an unfamiliar app; and anyone who wants the eSIM live before they reach the airport. It suits least the person standing at an airport kiosk, because the coupon has no route into that transaction. Sort it online in advance and the discount is yours; leave it until the terminal and it is not.
