Simbye's discount code EDC15 takes 15% off. That percentage only becomes meaningful once you attach it to a price, and the only figure Simbye publishes plainly is its entry point: prepaid data plans start from $1.99. Apply 15% to that and the saving is around 30 cents, leaving roughly $1.69. On a small single-country plan, the code is a rounding adjustment rather than a windfall.
The arithmetic scales, though. Because the discount is a percentage rather than a fixed amount, its cash value grows with basket size. A custom multi-country plan covering up to 10 countries with 5–50 GB of data and validity of 30 to 365 days will sit at the expensive end of the range, and that is where 15% converts into a meaningful sum. Simbye does not publish the prices of those larger builds, so the exact figure depends on what your configuration costs at checkout.
If you are trying to extract the most from the code, the logic is straightforward: one order, as large as your trip genuinely requires. Shopify checkouts generally accept one discount code per order, so EDC15 will not stack with another code. Splitting a trip into several small purchases does not multiply the discount; it simply applies 15% to several smaller subtotals, which produces the same proportional result with more admin.
The products where the basket naturally runs higher include regional bundles for Europe, Southeast Asia, Africa, South America, the Middle East and worldwide coverage, unlimited plans, virtual number products, and eSIMs that include calls for destinations such as the United Kingdom and Turkey. Validity periods run from 7 to 90 days on standard plans.
Several conditions can quietly remove the 15% or make it irrelevant:
No retroactive application. Shopify checkouts do not apply codes after the fact. If you pay without entering EDC15, the discount is gone for that order.
One code per order. If you hold another code you believe is worth more, you must choose between them.
Sale pricing is an unknown. Simbye does not state whether EDC15 combines with discounted plans. Check the order summary rather than assuming.
Top-ups are an unknown. Whether the code applies to top-up purchases is not stated. Top-ups are made through your account or the top-up page using your order number, and no reinstall is needed — but the discount's status there is unconfirmed.
Currency. The site supports multiple currencies including USD, EUR and GBP. Confirm the currency selector before paying, because the size of your saving is read in whichever currency you are charged.
A discount is worth nothing if the product cannot be used. Refunds are available only if the eSIM has not been installed or activated, so the moment you install the profile you have committed the full discounted amount. Carrier-locked handsets can refuse eSIM profiles, which is the most common way a traveller ends up with an unusable purchase. Device support covers iPhone XS and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer.
Unlimited plans carry a fair use policy of 2GB of high-speed data per day, after which speeds are reduced until the next 24-hour cycle. If you are paying a premium for "unlimited" expecting uncapped speed, the 15% saving does not offset a misunderstanding about what the plan delivers.
Choose a destination, region or custom multi-country build, pick your data amount and validity, and add to cart. Check the currency selector. At Shopify checkout, enter EDC15 in the discount field on the right-hand order summary — on mobile this sits under the "Show order summary" toggle — and press Apply. Confirm a discount line appears before entering payment details.
Two features protect the value once paid: the QR code is emailed immediately after payment confirmation and is also retrievable from your account or the top-up page using the order number, and an uninstalled eSIM stays valid for 180 days. Buying early at 15% off therefore does not waste the plan, since data does not count down until you arrive.
