eSIM platform case study · 2025: CloudOn eSIMTravel without limits.
CloudOn is a travel eSIM service built by Mirailit. Travellers buy a data plan before they fly, scan once on arrival and are online without a physical SIM card or roaming charges. We built the customer apps, the web storefront and the admin platform that runs it.

In the product
What CloudOn does
The features travellers actually use — and the ones any eSIM platform needs on day one.
Instant activation
Scan, activate, done — a plan bought in advance comes online before the traveller has left the airport.
No roaming fees
A single flat rate that holds across borders, so the bill is known before the trip rather than after it.
Multi-line management
Switch plans, pause lines and run up to five lines from one screen.
Real-time data monitoring
Live usage tracking with top-ups before a plan runs out mid-journey.
Flexible activation
Buy now, activate on arrival — the plan waits until the traveller needs it.
Dual-SIM compatible
The home SIM stays in place for calls while CloudOn carries the data.
Want one of your own?
CloudOn is the proof that we have shipped this before. We build the same stack under your brand — apps, storefront, provider integration and admin panel.
