Moving from a legacy eSIM to KR.One
There's no migration to run. The move happens the next time you buy a plan: the app adds a KR.One eSIM to your phone, and every plan after that attaches to it. Here's the one-time sequence, and what to do with the old eSIM (what a legacy eSIM is).
Steps
- Pick your destination and plan in the app or on knowroaming.com, and pay as usual.
- At checkout, choose the phone you're using. If it has no KR.One eSIM yet, the app starts adding one.
- Stay on Wi-Fi or data and keep the app open. It takes about a minute.
- Follow the two on-screen steps to turn on data roaming for the new KnowRoaming line. The app can add the eSIM, but only your phone's settings can switch roaming on.
- Tap Done. Your plan activates the moment you connect at your destination, and your days don't start until then.

Good to know
- Use up any data left on the legacy eSIM first. It doesn't transfer to KR.One (details).
- The old eSIM profile can stay on your phone. Once its plan has ended, remove it to free the slot: iPhone Settings > Cellular > the old KnowRoaming line > Delete eSIM. Samsung Settings > Connections > SIM manager. Other Android Settings > Network & internet > SIMs. Removing it doesn't change anything on your account. See Should I remove my KnowRoaming eSIM after a trip?
- Check that data runs through the new line, not the old one. See Use your KnowRoaming plan for data instead of your home SIM.
- Your legacy eSIMs stay listed under My plans, behind Show legacy eSIMs. Archive the ones you're done with.
- Trip three and onward: nothing to add. Pick the destination, pay, and the plan attaches to your KR.One eSIM.

Häufig gestellte Fragen
How to use an eSIM while backpacking is surprisingly simple. First, ensure your phone is unlocked and eSIM-compatible. Then, download the provider's app (like KnowRoaming's). You can choose your plan and add the eSIM digitally through the app, often by scanning a QR code. Once added, just enable data roaming for your eSIM, and you're ready to go, no physical cards or airport kiosks needed.
No swapping SIM cards, no kiosk queues at the airport, set it up once and it's ready every time after.
With KnowRoaming, setup takes less than five minutes. Using the automatic setup in the KnowRoaming app, you can download and add your eSIM in just a few taps. This makes it one of the fastest and most reliable ways to get connected before your trip.
Simply add the eSIM profile on your unlocked, eSIM-compatible device before you travel. Once you arrive in a supported country, turn on your eSIM, and you'll be connected!
