Each eSIM installs once, on one device, and can't be moved to another phone.
Your options
- Use it on that phone. If it's travelling with you (a partner's phone, a tablet), it works fine there.
- Get another eSIM for your own phone. Destinations.
Didn't actually finish installing?
Then nothing has happened. Install it on the right phone, any time within 180 days of buying it.
