How to Install an eSIM on iPhone: Step-by-Step Guide

Installing an eSIM on your iPhone is simple and only takes a few minutes. Before your trip, it's a good idea to install your travel eSIM so you're ready to connect when you arrive at your destination.

This guide will walk you through the installation process.

Before You Start

Before installing your eSIM, make sure that:

• Your iPhone supports eSIM.
• Your iPhone is carrier-unlocked.
• You have received your eSIM QR code by email.
• You have a stable Wi-Fi connection during installation.

⚠️ Important

Installation and activation may vary depending on your eSIM plan. Some eSIMs can be installed before you travel, while others should only be activated upon arrival at your destination.

Always follow the activation instructions provided with your specific eSIM purchase.

✅ Check Your iPhone's EID (Important)

The most reliable way to confirm your iPhone supports eSIM is to check whether it has an EID — the unique identifier of your device's built-in eSIM. If your iPhone has an EID, it can use an eSIM.

To check your EID:

• Go to Settings → General → About.
• Scroll down and look for EID.
• If an EID number is shown, your iPhone supports eSIM.

You can also dial *#06# on your iPhone to display your IMEI and EID.

⚠️ If there is no EID, your iPhone does not support eSIM. Some region-specific models — such as iPhones sold in mainland China or certain dual physical-SIM versions — do not include an eSIM, even if the model number appears in the list above.
