App & install FAQ
Is the TripoSIM app on the App Store or Google Play?
TripoSIM runs as a Progressive Web App (PWA), so you install it straight from triposim.com — no App Store or Play Store needed. You get the full app experience (home-screen icon, full-screen, offline access to your eSIMs) without waiting for a download or store approval. Native store apps are coming, but the PWA is faster, always up to date, and uses far less storage.
What is a PWA and is it safe?
A PWA is a website that installs like an app. It is delivered over the same secure HTTPS connection as our website, takes only a fraction of the storage of a normal app, and updates instantly — there is nothing to manually update. Your eSIMs, QR codes, and account all live inside it.
Do I need the app to buy an eSIM?
No — you can buy on triposim.com in any browser. But installing the app makes it one tap to view your QR codes, check data usage, top up, and reinstall an eSIM on a new trip.
Will my eSIMs work offline in the app?
Yes. Once installed, your eSIM QR codes and details are available in the app even without a connection — handy the moment you land abroad before your data activates.
How do I open the app after installing?
Just tap the TripoSIM icon on your home screen — it opens full-screen like a native app, with no browser bars.
