Your eSIM isn't wasted.

Because it was never installed, it hasn't started. It isn't tied to you or to your phone, and its days only begin counting when it first connects at your destination.

So you can give it to anyone whose phone does take an eSIM — someone you're travelling with, or anyone going the same way. Forward them your order email, they scan the QR code, and it's theirs. The window for that is printed on the plan's detail sheet.

We can't refund it, because checking the phone is the one thing only you can do and you confirmed it before paying. But you don't have to throw it away.
