Mobile data in 180+ countries, activated from one storefront in minutes.

Travelers still deal with a problem that should have died years ago: landing in a new country, hunting for a SIM kiosk, and paying roaming charges that cost more than the flight snacks. Roam Digi's founder saw the opening — eSIM technology lets a traveler buy a data plan before takeoff and activate it with a QR code.

But selling connectivity across 180+ countries is a catalog problem, a payments problem, and a trust problem all at once. The platform had to make finding the right plan effortless, deliver the eSIM instantly after checkout, and feel credible enough that a stranger hands over card details for something invisible.

We modeled the business as three pipelines that must never break: discovery (traveler finds the right plan), payment (money moves safely across borders), and delivery (the eSIM reaches the phone in seconds). Each pipeline got designed, built, and stress-tested on its own before being stitched together.

Discovery drove the architecture. Everything starts from a destination search, so the catalog — every country, region, and plan variant — was modeled first, and the UI built around getting from 'I'm going to Turkey' to a priced plan in two interactions.

“No kiosks, no plastic SIMs, no roaming bills. Pick a destination, pay, scan a QR code — connected before the plane doors open.”

A complete eSIM storefront built around destination search. Travelers type where they're going and get local, regional, and global plans with transparent pricing — no telecom jargon, no fine print buried three pages deep.

Checkout delivers the eSIM instantly: a QR code on screen and in the inbox, with step-by-step activation guides for iPhone and Android. User accounts track active plans and data usage, and a content hub answers the questions every first-time eSIM buyer has.

The platform ships with companion mobile apps on Google Play and the App Store, so repeat travelers can top up and switch plans without touching a laptop.

Roam Digi sells connectivity in 180+ countries through one storefront that runs itself — checkout to connected phone in under five minutes, no human in the loop. The platform handles the catalog, payments, and provisioning end to end, leaving the team free to work on growth instead of operations.
