Embedded eSIM for Fintech, Super Apps and Travel Apps

Quick answer

Fintech apps, neobanks, super apps and travel apps can embed white-label eSIM data so users buy travel connectivity inside the app, paid from their balance or card. Through Fully Signal's REST API, the app lists plans, creates orders, shows the install link and handles top-ups — earning margin and daily engagement while users travel.

Users already open their banking or travel app abroad — to pay, convert currency, show a booking. Adding eSIM data turns that moment into revenue and makes the app even more essential on the trip.

Why apps embed eSIM

  • Natural fit: travel is when users need data most — and when they open these apps
  • Revenue: margin on every plan and top-up
  • Engagement: users return to check data, top up and plan the next trip
  • Differentiation: "Your card and your data, in one app"

Use cases

App typeeSIM moment
Neobank / card appCard spend abroad detected → "Get data for Spain"
Travel booking appTrip booked → eSIM for the destination
Super appTravel section with flights, hotels and data
Loyalty / airline miles appRedeem points for data
Expense / corporate travel appCompany-paid data for employees

The in-app flow

  1. Show plans for the user's destination (catalogue from the API)
  2. Pay with the in-app balance or card
  3. Create the order from your backend with an Idempotency-Key
  4. Install: open the install link on the device — one-tap install on supported phones
  5. Manage: show remaining data and offer top-ups
  6. Notify via webhooks on activation and expiry

Technical guide: integrate an eSIM API.

Security and compliance

  • Keep API keys server-side; the app talks to your backend
  • Use scoped keys and IP allowlists
  • Use team roles to separate engineering, finance and support access
  • Follow your own KYC/AML processes for payments as usual — the eSIM is a digital product purchase (compliance basics)

Commercials

You pay wholesale from a prepaid balance with auto top-up, and set your own retail prices — including loyalty pricing or bundles for premium tiers. Higher volume unlocks better wholesale tiers. Pricing.

FAQ

Can a banking app sell eSIMs?

Yes. Through a white-label eSIM API, a banking or fintech app can sell travel data under its own brand.

Does the user need to leave the app to install?

They open the install link, which on supported phones launches the phone's own eSIM setup with one tap, then return to the app.

How do we show remaining data in the app?

Read the eSIM's status and remaining data from the API (GET /api/v1/esims/{iccid}), and update on webhooks.

What does it cost to integrate?

The API and sandbox are free to use. You pay wholesale prices only for eSIMs you sell.
