eSIM.net Voucher Code EDCNET10 is a partner code that removes 10% from your basket at checkout with the UK eSIM retailer eSIM.net, and because the rate is flat rather than an "up to" ceiling, you pay 90% of the listed price whichever plan you choose. This guide is about the mechanics rather than the marketing: the checks to do before you reach the payment page, the exact point the code is entered, how to read the total to confirm the reduction landed, and the sequence to follow if nothing changes when you apply it.

A discount on a product your phone cannot use is worth nothing, so the first step in this walkthrough happens before you add anything to the basket. eSIM.net delivers by QR code — buy, scan, install — and the company says an eSIM can be received and installed within five minutes. That speed only helps if the handset supports eSIM in the first place.

Dial *#06# on the device. A compatible phone displays an EID alongside the other identifiers. If there is no EID, the device does not support eSIM and no amount of discount will change that. Note also that Apple makes eSIM-capable tablets while Samsung tablets do not support eSIM, so a tablet purchase needs the same check.

The second pre-purchase decision shapes everything that follows. eSIM.net sells two genuinely different categories of product, and they carry different terms:

Deciding between the two first saves you unpicking an order later, because the refund position is tight and, for at least some products, installation is the point of no return.

The store's help centre refers only to promotions appearing "at checkout" and does not name the field or describe its position on the page, so expect a standard code box of the kind most online shops use rather than a specific labelled step. The order of operations is straightforward:

Whether the code also works inside the mobile apps, which are available on the App Store and Google Play, is not documented. The website checkout is the known route, so use it if you want certainty. Checkout accepts GBP, USD, EUR, Australian dollars and Canadian dollars.

There is no mystery to verifying a flat percentage: subtract a tenth and see whether the figure on screen matches. Working from published homepage prices dated 11 September 2026, which can change, the arithmetic runs like this. The O2 Travel plan with 20GB across 48 European countries is listed at £14.50, so the discounted figure is £13.05. The Vodafone Travel plan with 25GB across 76 countries is listed at £24.00, which becomes £21.60. The EE Europe Travel Plus plan with 60GB at £18.50 becomes £16.65, and the O2 Europe Travel Plus plan with 35GB at £18.00 becomes £16.20. The Bouygues Telecom 120GB Europe plan at £32.50 comes to £29.25.

If the total on your screen matches the listed price minus a tenth, the code has applied. If it matches the listed price exactly, it has not. If it sits somewhere in between, something else is in play — most likely a promotional price rather than a code, which is covered below.

Because the reduction is proportional, it scales with the order. On the SMS-only global eSIM listed at £6.00, a tenth is small change. On a large multi-country bundle it is more noticeable. That is a reason to check the total carefully on cheaper items, where a 10% change is easy to miss at a glance.

Separate from any code, eSIM.net sometimes applies promotional pricing to individual products — the homepage has carried a promotional Orange Spain price, for example. Whether a code and a promotional price can both apply to the same order is not something that can be answered in the abstract. The basket total is the only reliable answer.

A practical way to test this is to note the listed price of the item before you reach checkout, then compare it against the total after applying the code. If the promotional price is already lower than the list price, work out what a tenth off each figure would be and see which the checkout matches. That tells you whether the two have stacked or whether one has replaced the other, without needing any published rule.

eSIM.net's help centre states that the company does not currently run discount codes of its own, that promotions may instead appear at checkout when you make a purchase, and that a customer who received a code from an affiliate partner should contact that partner if it causes trouble. EDCNET10 is a partner code, so that guidance applies directly to it. Before escalating anywhere, run through the ordinary causes of a failed code:

If it still does not take, the retailer's own instruction is to go back to the partner that supplied the code. eSIM.net support runs through email at support@esim.net, a helpdesk knowledge base, a contact form and a chatbot, but hours are not published, so do not plan a purchase around an immediate reply.

For a rolling operator plan, the most important post-purchase task is understanding renewal. The terms say a plan that is not cancelled renews at the end of the 30-day period and the card is billed again. Cancellation is done in MyeSIM, the management area on the website: select the plan and choose "Cancel Plan". The plan continues working until the period ends, after which the phone number is lost, and a cancellation can be reversed before the period ends if you change your mind. Data allowances on rolling plans renew on the 1st of the month, and the first month is pro-rated by purchase date.

It is not documented whether EDCNET10 reduces only the first month of a rolling plan or every renewal, so after your first billing, open MyeSIM and read the renewal price shown there. That figure tells you what the card will be charged next time, which is more useful than any assumption. Complaints in the retailer's public reviews cluster partly around missing usage or renewal reminders, which is a direct argument for setting your own calendar reminder a few days before the period ends.

Refunds are tight. Once payment is made for a month, the company says it cannot refund that month, and unused data, calls or texts are not repaid when a 30-day bundle ends. For Bouygues Telecom eSIMs a refund is possible only if the eSIM has not been installed. That specific rule should not be assumed to cover every product, but it illustrates a pattern worth respecting: installation is commonly the point of no return, so read the refund line on the listing before you scan the QR code.

Being clear about the gaps is more useful than filling them with guesswork. It is not documented whether EDCNET10 applies to every product or excludes rolling subscriptions, top-ups, the Global pay-as-you-go credit, the SMS-only plan or promotionally priced items. No minimum spend, expiry date, per-customer limit or first-order-only condition is published, which means none should be assumed either in your favour or against it. The checkout total remains the authority on all of it.

A fair-usage policy also applies once the plan is running. Reselling, gateway devices and bulk messaging are prohibited, and extended roaming — 60 or more days within four months — counts as a breach, with speed shaping or disconnection as possible consequences. Africa plans note 10GB at high speed followed by a fair-use cap of 128 kbps.
