XeroSMS
A React Native app providing instant SMS verification codes, temporary virtual numbers, and global eSIM connectivity — built for privacy-conscious users who need disposable numbers on demand.
The client needed a mobile app that could provide SMS verification codes, temporary virtual numbers, and eSIM services across both iOS and Android from a single codebase.
Users in this space care deeply about speed and privacy — they need a number in seconds, use it once, and move on. The app had to feel native on both platforms while keeping the core flow to under three taps.
Built with React Native and Expo for cross-platform delivery. The core flow — pick a country, pick a service, get a number — is a single linear path with no branching UI.
The eSIM integration required platform-specific native modules, but everything else shares code. Push notifications alert users when verification codes arrive, keeping them out of the app until the moment that matters.
Shipped to both the App Store and Google Play, with 1,000+ downloads on Android and a steady user base on iOS.
The three-tap flow and push notification model keep session times short and return rates high — users come back because the tool disappears when it should.
