You might wish to take an eSIM card out of your iPhone after installing it and using it to access the internet. As there is no drawback to retaining the eSIM on your phone, you don't need to delete it. However, here's how to erase it if you want to for any reason:

What you should know before deleting an eSIM from your iPhone:
- Cancelling a data plan and removing an eSIM from your iPhone are two different things. Our eSIM plans are prepaid, so there is nothing to cancel, but any data left on the eSIM is lost once you delete it.
- You cannot reinstall the eSIM after deleting it.
How to remove an iPhone eSIM:
- Go to Settings > Cellular and Mobile Data.
- To delete an eSIM, tap on it and choose "Remove cellular plan."
