Buying a travel eSIM involves several small decisions in a row: which plan, which device, which payment method, and where the discount field hides. Most of them are quick, but they are easy to fumble when you are packing or standing in a departures hall. What follows is a condensed reference you can read once and keep to hand, rather than a step-by-step tutorial. It covers what the voucher is, the single screen that matters, and the lines you should not expect it to change.
Code: EDCC10
Value: 10% discount on the plan price shown in the Airalo store
Applies to: eSIM data plans bought through standard checkout on airalo.com or the iOS/Android app
Entry point: the promo/discount/voucher code field on the order summary or payment screen
Timing: must be applied before payment; it cannot be added to a completed order afterwards
Typical spend: plans are usually priced in single or low double-digit dollars, with about $5 cited for a small plan and around $20 for a mid-sized regional plan
Enter the code exactly as written, with no spaces, then check that a discount line appears and the total falls by 10% before you authorise payment.
In the app, the code row appears above the total on the order summary and is tappable, usually marked with a tag or ticket icon. On the web, it is a text box inside the order summary panel. Either way you reach it by searching the destination, opening the plan, confirming the data allowance and validity, and pressing Buy Now. You need to be signed in to an Airalo account first — by email, Google or Apple sign-in — because eSIMs are managed, reinstalled and topped up from that account.
Payment is by card or, depending on region, Apple Pay, Google Pay or PayPal. A receipt is emailed once the order goes through.
The discount reduces the price of the package. It does not increase the data allowance or extend the validity window. Unused data does not roll over once validity ends, and validity generally begins when the eSIM first connects to a network at the destination rather than at the moment of purchase.
Other lines stay untouched. Bank foreign transaction fees and exchange rates sit outside Airalo's checkout and are not reduced. If you later obtain a refund or raise a chargeback on a discounted order, you get back the amount actually paid, not the pre-discount price, and the voucher itself does not come back to you.
Assume one code per order, and assume codes do not stack with other offers or with an active sale. Codes on the platform are typically single-use per account, and creating duplicate accounts to reuse one breaches retailer terms and puts the accounts at risk.
Several details about EDCC10 are not published externally, so the payment screen is the only reliable test:
The exact expiry date of the code
Whether it is single-use per account or works on later orders
Whether it is limited to first purchases or also covers repeat ones
Whether top-ups, bought from My eSIMs, count as eligible orders
Whether any minimum order value applies
Whether specific package types or promotional plans are excluded
Whether store credit, gift-card purchases or Airalo's own referral credit can combine with it in one transaction
In each case, apply the code and watch the total. If it does not move, the condition has not been met.
Open My eSIMs and install using direct install or the QR code, or by entering the SM-DP+ address and activation code. Installation needs an internet connection, so do it at home over Wi-Fi and leave the line switched off until you land. On arrival, select the Airalo line and turn on Data Roaming for that line only. If nothing connects, toggle airplane mode or select a partner network manually.
One last device note: the phone must support eSIM and be carrier-unlocked. Airalo publishes a compatible device list, which generally includes iPhones from the XS generation onwards, recent Google Pixels, and Samsung Galaxy S and Z flagships.
