The discount happens in a single moment on day one, and everything after that is about the plan rather than the code. On esim.net you first pick a plan type — UK local, single destination travel, or multi-country — and confirm the data allowance and validity period on the product page. Set the currency in the top navigation selector before you go any further, then add the plan to the basket.
On the basket or checkout page, the order summary carries a promo/voucher/discount field above or beside the total with an Apply button. Type or paste EDCNET10 there and press Apply. Wait for the summary to redraw with a discount row and a lower total before you pay: the code cannot be added retroactively once payment has gone through. You then log in or create an account with an email address, and pay through the Stripe card form, which supports GBP, USD, EUR, Australian dollars and Canadian dollars.
Delivery is digital and immediate in form: the eSIM arrives as a QR code by email, with installation instructions. There is no physical delivery to wait for. On an iPhone the path is Settings > Cellular/Mobile Data > Add eSIM; on Android it is Network and internet > SIMs > Add more. The handset needs to support eSIM and be carrier-unlocked. No credit check and no KYC identity document upload is involved.
One day-one detail matters more than the discount itself. Some plans begin counting down at purchase rather than at installation — the 30-day Vodafone Travel plan starts at the time of purchase. Each product page states whether that particular plan's validity runs from purchase or from installation, so read it before you apply the code, not afterwards. If you are buying days before you travel, that single line decides whether you have bought 30 usable days or fewer.
Once installed, the experience depends on the plan you chose at the discounted price. A Vodafone UK eSIM gives UK data, unlimited UK calls and texts, a UK +44 number, 5G where available and WiFi Calling. Travel plans from O2, Vodafone, EE and Three, plus European networks such as Orange Spain, Orange France, Bouygues Telecom and SFR, cover single destinations or roam across several countries, particularly within Europe. In many countries you can pick the specific local network your plan runs on.
During that first week the mobile app and the MyeSIM web area are where you check your balance and top up. Two behaviours are worth knowing early. If you took the Vodafone Travel VIP option, coverage extends to a further 75 countries and international calling is enabled, but usage in those additional countries incurs a daily fee and a credit card is required. If you bought the SMS-only option that allows unlimited free inbound SMS, note that it carries no calls, no outbound SMS and no data — attempting to use them disables the service.
When the allowance or validity runs out, top-ups happen through the app or MyeSIM area. UK plans support number portability via PAC code, so a UK number can be brought across rather than abandoned. Some plans advertise a subscription saving at checkout for 3 or 6 months, which is a separate mechanism from the voucher.
The code does not follow you into that stage. It applies to the order it was entered on, and codes of this type are normally one per order rather than stackable with another code. Heavily reduced or promotional bundles are sometimes excluded from further percentage discounts, so a deeply cut plan may not accept it at all.
Whether EDCNET10 combines with the 3 or 6 month subscription saving is set by the store and is not stated here — the basket total is the only reliable answer. Likewise, whether any given plan's validity starts at purchase or installation is published on the individual product page rather than as a blanket rule. eSIM.net is a UK-based, UK-registered reseller of Tier 1 operator service rather than a network itself, and compatibility information is published on the site.
