My legacy eSIM still has data. Can I keep using it?

Yes. A legacy eSIM with data left keeps working until the plan runs out or expires, whichever comes first. Nothing changes on your phone, and you don't need to do anything.

More detail

A legacy eSIM is one you added before KnowRoaming moved to KR.One, when each eSIM worked for one destination (what a legacy eSIM is). Your account shows it under My plans, behind Show legacy eSIMs, with the data left and the expiry date.

Keep using it the way you always have: data roaming on for the KnowRoaming line, roaming off for your home SIM. When the plan ends, the eSIM stays on your account as a record, and your receipts stay in Order history.

What you can't do is add more data to it. Top-ups and new plans go on a KR.One eSIM, which you add once and keep for every trip after (why). If you run out mid-trip, buy your next plan as usual. The app adds a KR.One eSIM to your phone in about a minute, and your new plan attaches to it.

The data left on a legacy eSIM doesn't transfer to KR.One, so use it up first. When you're ready to switch, the steps are in Moving from a legacy eSIM to KR.One.
