Sim Local Discount Code ESIMDISCOUNT10 is a checkout code that takes 10% off your order at Sim Local, the Irish travel-eSIM retailer at simlocal.com. It is a flat rate rather than an "up to" headline, so the discounted total is always 90% of the pre-discount subtotal. The mechanism is simple, but the moment it matters is short: the code has to be in the field and the total has to have dropped before you press pay. This walkthrough covers the redemption path in order, what a successful application looks like, and the sensible next moves if nothing happens.
Before you reach checkout
Most failed redemptions are not code problems at all. They are basket problems, or device problems discovered too late. Two minutes of preparation removes the majority of them.
First, confirm your handset supports eSIM. A travel eSIM is a digital SIM profile you download to the phone so you have data abroad without swapping a physical card or paying roaming rates, and none of that works on a device that cannot hold one. Second, decide what you actually need before you start hunting for a code field. Sim Local's range includes single-destination and multi-destination eSIMs, unlimited plans, plans with calls and texts, and plans aimed at students. Picking the plan type first means you are not re-entering a code after changing your basket.
Third, be realistic about what the saving will be. Sim Local publishes "from" prices, which are starting prices for each destination's cheapest plan rather than typical baskets. On a Canada 1GB plan with a starting price of $5.00, 10% off is $4.50 — fifty cents. On a UK 20GB plan with a starting price of $13.50, the total becomes $12.15, a saving of $1.35. The code is worth more in absolute terms on larger allowances, unlimited plans, multi-destination bundles, or several eSIMs bought at once for a family or group. Knowing that in advance stops you spending twenty minutes on a fifty-cent problem.
The redemption steps in order
Go to simlocal.com and choose your destination, or the multi-destination bundle that covers your route.
Select the plan type you need — single-destination, multi-destination, unlimited, or one that includes calls and texts.
Choose the data allowance and duration, then add the plan to your basket. If you are buying for several travellers, add every eSIM now so the discount is calculated on the full subtotal.
Proceed to checkout and locate the discount or coupon field. The exact label used at this store is not published, so look for anything along the lines of discount, coupon or voucher.
Type ESIMDISCOUNT10 exactly as written, with no spaces, and apply it.
Read the order total again. A flat 10% discount should leave you paying 90% of the pre-discount subtotal.
Complete payment, then download the eSIM through the Sim Local app or the instructions you are sent.
Step six is the one people skip, and it is the only step that proves anything. The percentage on a code is a claim; the total on your screen is the fact.
Where the code field hides
Online checkouts commonly tuck the code box behind a small link rather than showing it as a permanent box. If you cannot see a field, expand the order summary — on many layouts the summary collapses on smaller screens and the code entry lives inside it, sometimes behind a prompt such as "have a code?". Scroll the full length of the payment page before concluding the field does not exist.
There is one platform question worth flagging. Sim Local has apps for both iOS and Android, and describes "one-click downloads in the Sim Local app". Whether ESIMDISCOUNT10 works inside the app checkout as well as on the website is not published. If the app checkout offers no code field, the website is the safer route for a discounted purchase; you can still download and manage the eSIM in the app afterwards.
What a successful application looks like
You are looking for a visible change in the money, not a message. Typical signs, in rough order of reliability:
The order total falls, and the new figure is 90% of what was showing a moment earlier.
A discount line appears in the order summary, separate from the item price.
The code itself is echoed back somewhere in the summary, often with an option to remove it.
The reduced figure is the one carried through to the payment screen, not just to the basket.
Do the arithmetic yourself rather than trusting the layout. A flat 10% is the easiest kind of discount to check: knock a tenth off the subtotal in your head and compare. If the displayed saving is smaller than a tenth of the subtotal, something in the basket may be excluded, or the discount may be applying to part of the order only. Either way, you now know before you have paid.
After payment, keep the order confirmation email. Refund requests at this store need the order number and the email address used for the purchase, so that message is your receipt and your paperwork in one.
If the code does not apply
The first rule is the important one: do not pay and hope it gets fixed afterwards. Discounts at almost every online store are calculated at the point of payment, not retrospectively, and support teams are rarely able to rewrite a completed order. Treat an unchanged total as a stop signal, not a formality.
Work through the cheap explanations before assuming the code is at fault:
Re-type the code by hand. Copying from a page or a message often brings a trailing space or a line break with it, and the field may not tolerate either.
Check the characters. ESIMDISCOUNT10 ends in the digits one and zero, not letters.
Confirm you pressed apply rather than just leaving the code sitting in the box, and that the page finished reloading.
Make sure you are on the website checkout if the app is where you were trying.
Clear the basket, re-add the plan and try once more, in case a mid-checkout change to the order stripped the discount.
If it still does not take, be aware of the limits of what is publicly known. Whether ESIMDISCOUNT10 applies across every plan type — unlimited, calls-and-texts, student and multi-destination included — is not published. Neither is any minimum spend, expiry date, per-customer cap or first-order-only restriction. That means a non-applying code is not proof you did anything wrong; it may simply be a basket the code does not cover. Support runs 24/7 on WhatsApp messaging, there is email at customerqueries@simlocal.com, a Zendesk help centre, and staff in the company's airport stores. The store says tickets are typically answered within 24 hours. Asking before you pay is far more productive than asking after.
Do not confuse this with the referral discount
Sim Local also runs a refer-a-friend scheme, and because it involves the same 10% figure it is often mistaken for this code. Under that scheme the referrer receives US$5 per friend, and the referred friend gets 10% off their first purchase on a minimum order of £/€/$20. That discount is applied automatically at checkout and can be used once. The store describes its own referral codes as single-use and applied at checkout.
Three consequences for your redemption. The referral 10% is not the same thing as typing ESIMDISCOUNT10 — one arrives automatically through an invitation, the other you enter yourself. The two figures should not be added together into an imagined larger discount. And whether both can sit on the same order is not answered anywhere public, so the checkout total is again the only test. The minimum order of 20 belongs to the referral scheme and does not necessarily attach to this code.
After you pay: the activation line
Redemption does not end at payment, because for a digital product the refund terms are what protect a discounted purchase. Sim Local's policy turns on one boundary: activation. If you have not activated your eSIM, you can request a full refund within 14 days of purchase — the store calls these "No Quibble Refunds". Once the eSIM is activated it is considered used and is no longer eligible for a refund. If it could not be activated because of a technical problem on Sim Local's side or the network's, the store says it will refund even outside the 14 days. Requests go by email to customerqueries@simlocal.com with the order number and the purchase email, and refunds take 5–10 business days depending on the bank. Activating waives cancellation rights under consumer law, and the policy page references the EU Consumer Rights Directive.
The practical instruction that follows is short: buy the eSIM, download it, and do not activate it until you actually need data. If the trip falls apart and the eSIM is untouched, you are inside a 14-day window. If you activate it at home to check it works and then cancel, the money is spent.
A last sense-check before payment
Compare the discounted total against what the same trip would cost elsewhere, rather than fixating on the percentage. Check the allowance and validity period suit your trip length, because a cheap plan you exhaust on day two is a false economy. Sim Local advertises 200+ destinations and 150+ countries on local networks with 5G where available, and says it has served 4 million customers worldwide, though which local networks are used in any particular country is not published. There is also a price-match page covering UK eSIM deals, with conditions that are not worth assuming. Applied properly, the code is a small, clean step in an otherwise quick purchase — worth the extra field, but never the whole reason to buy.
