When should I install my eSIM?
To ensure a smooth setup process, we recommend installing your eSIM just before your departure, as installation requires a stable Internet connection.
Do I need a new eSIM for every trip?
No. That's the point of KR.One. Keep it installed and add a new plan in the app whenever you travel.

A whole new KnowRoaming: Install once, add plans forever.
We've moved to a universal eSIM. Instead of a new eSIM for every destination, you now have one eSIM that works wherever you travel. Install it once, and it stays on your phone for every trip after that.
Heading somewhere new? Just add a plan for that destination in the app and you're ready to go. No reinstalling, no scanning new QR codes, no setup every time you travel.
We've also given the app a fresh new look. It's cleaner and easier to use, so finding the right plan and managing your data takes just a few taps. Everything runs faster and smoother, from browsing destinations to getting connected when you land.
