AloAlo eSIM
A travel eSIM store — buy prepaid data plans for 200+ countries in the app or on the web, install them in a tap and skip roaming charges.
AloAlo is our own travel eSIM product. Travellers pick a destination, compare data plans and buy one in a couple of taps; the eSIM is provisioned through a carrier partner API and installed straight onto the phone, so there is no physical SIM and no roaming bill.
We built the iOS and Android app with React Native and Expo, a NestJS and Prisma backend that handles plan catalogues, orders and Stripe payments, a TanStack Start admin panel for operations, and a fast marketing site — all deployed on Railway.
