How to get an iD eSIM

Getting an eSIM is definitely more convenient and fast-paced, as compared to registering for a UK SIM card (or any physical SIM card). This is one of the main advantages of eSIMs in the eSIM vs physical SIM debate.

Follow these steps to ensure a successful iD eSIM purchase:

Pick one of the plans mentioned above and select the eSIM option.
Enter any required details, and pay using a verified method.
You’ll receive an eSIM email once your order is confirmed, containing a QR code to download your eSIM.
Follow the steps in the email to successfully download the eSIM, ensuring WiFi is enabled the entire time.
Wait approximately up to an hour for your eSIM download to complete.

Once this is done, you’ll be able to use your eSIM.

How to install your eSIM from iD Mobile

Having trouble downloading your eSIM via QR code? Each brand offers slightly different ways of doing this.

Set up eSIM on iPhone: Go to Settings > Mobile Service > Add eSIM > Use QR code. Then scan the QR code from your email and follow the instructions to complete the setup.
Set up eSIM on Samsung: Go to Device Settings > Connections > SIM Card Manager > Add Mobile Plan > Scan Carrier QR code. Scan the QR code from your email and follow the instructions to complete the setup. A similar process applies to all Android devices, though some steps may differ slightly.
Set up eSIM on Google Pixel: Go to Device Settings > Network & Internet > Mobile Network > Download a SIM instead > choose to add via a QR code. Scan the QR code from your email and follow the instructions to complete the setup.
