Does SOS-Expat work on smartphones without downloading an app?

Yes, SOS-Expat is a progressive web app (PWA) fully accessible from your smartphone browser, with no installation required. It is compatible with all modern devices.

• iPhone / iOS: works perfectly on Safari (iOS 14+). You can add the site to your home screen for a native app-like experience
• Android: compatible with Chrome, Firefox, and Samsung Internet
• Tablet: interface optimized for tablet screens as well

The interface is fully responsive and adapts to your screen size. No special permissions (microphone, camera) are needed since the call is received via your regular phone network, not the app.
