Hi @JvB
Welcome to the customers help customers Community of Vodafone.
Transfer or reinstall eSIM?
With the eSIM voucher
If you still have the eSIM voucher, you can delete the eSIM profile from your old device. Follow the instructions on the voucher to install the eSIM on your new device.
Via My Vodafone
Wait a while before deleting the eSIM profile on your old device. Log in to My Vodafone and go to 'View or transfer your eSIM'. There you will find your eSIM data and in a few steps you can activate your eSIM on your new device.
Good to know: Do not remove the eSIM profile from your device if you have lost the voucher and there is nothing about your eSIM in My Vodafone. You still have your voucher and if it doesn't work, it's best to visit a Vodafone store . Drop by one of the Vodafone stores and they help you out.
