Yesim sells travel eSIM data plans that install digitally on a phone instead of arriving as a plastic SIM. The promo code EDC15 takes 15% off at checkout, entered in the "Redeem code" field after you have chosen a plan. Whether that 15% is actually useful depends far more on how you travel and what handset you carry than on the size of the discount itself. Below are the realistic use cases where the code earns its place, and the ones where it does not.
The short-trip traveller with a modern phone. Yesim's fixed packages give a set data amount for a set number of days, which fits a one- or two-week trip neatly. You buy a country plan, apply EDC15, and pay 15% less than the listed price. Activation is quick \u2014 described variously as a couple of minutes and as 5\u201310 minutes after setup \u2014 so it works even for someone buying at the airport gate.
The multi-country traveller. Regional and global bundles let the same eSIM stay active while you cross borders, so you are not repurchasing at each frontier. When a single larger bundle replaces three separate country plans, a 15% cut applies to the whole thing at once.
The advance planner. Plans can be purchased in advance and activated within 12 months. If you have a trip booked for later in the year, you can use the code now and hold the plan until departure, rather than hoping a discount exists when you travel.
The light data user on pay-as-you-go. Yesim also offers a pay-as-you-go option where you top up credit and pay only for what you use. Whether EDC15 applies to credit top-ups rather than data packages is not stated, so check the order total before assuming it does.
Anyone without an eSIM-compatible handset. Yesim requires a modern iOS or Android device that supports eSIM. No amount of discount helps if the phone cannot install the profile. Confirm compatibility first; this is the single most common reason a purchase goes wrong.
People who need a working phone number abroad. Yesim's eSIM plans are data-only. There is no number for voice calls or standard SMS. Users rely on WhatsApp, Telegram or FaceTime over data instead. If you are expecting calls from a hotel, a local taxi firm or a bank that only calls landline-style numbers, a data-only eSIM on its own will not cover you. Yesim does sell a separate virtual phone number service for receiving incoming SMS, which works independently from an eSIM \u2014 but whether EDC15 applies to virtual number purchases is not stated.
Travellers who need guaranteed speeds. Yesim is an MVNO: it buys wholesale access to carrier networks rather than owning towers, partnering with over 800 local mobile operators. Speed therefore depends on the local partner network in each destination. If your work depends on a specific throughput, the discount does not change that variable.
Anyone already holding a better offer. It is not stated whether EDC15 stacks with in-app credit, seasonal sales or other promotions. If you already have credit or are looking at a sale price, compare the two totals rather than assuming they combine.
Go to yesim.app in a browser, or open the Yesim app on iOS or Android.
Search your destination and compare country, regional and global plans.
Add the plan and continue to checkout.
Enter EDC15 in the "Redeem code" field, which may be collapsed inside the order summary.
Apply it and confirm the total has dropped by 15% before authorising payment. The discount is reflected in the order total instantly.
Pay, then install the eSIM by scanning the QR code or through the app.
Yesim uses an in-app currency called Ycoins for balance top-ups. Auto-refill for Ycoins is enabled automatically after you top up unless you turn it off. If you only intend to buy once, switch it off rather than discovering repeat charges later.
EDC15 is a straightforward percentage cut on a product with real constraints. It rewards travellers with eSIM-capable phones, defined trip lengths and a willingness to use data-based messaging apps. It does little for anyone needing voice service, anyone on an older handset, or anyone whose coverage question is about which countries a particular global product includes \u2014 coverage does not necessarily match across Yesim's various global products, so verify that on the site before you pay.
