Hi ​@KoalaK 

You will need to contact our live chat team at https://www.idmobile.co.uk/live-chat so they can assist you with getting an eSIM or you can do it via the online account as well with the below steps:

Steps to request an eSIM in the iD Mobile app:

Open the iD Mobile app and log in
Go to “Plan”
Tap “SIM & Phone Management”
Select “Request a replacement SIM or eSIM”
Choose “Get a replacement eSIM”
Check your email address is correct
Confirm by tapping “Yes, I want a new eSIM”

What happens next:

You’ll receive an email with a QR code
Scan that QR code on the phone you want to use
Make sure you’re connected to Wi-Fi during setup
Activation usually completes within a short time (sometimes up to about an hour)
