iPhone eSIM Compatible Models and Preparation Before Installation

Before you begin the installation, please confirm if your iPhone supports eSIM functionality. Generally, iPhone XS, XR, and later models all have built-in eSIM functionality, including iPhone 11, 12, 13, 14, 15, and the latest iPhone 17 series. However, there might be differences across regional versions: some versions still retain a physical SIM card slot, especially earlier models sold in Hong Kong and mainland China, which may not yet support eSIM. It is recommended that users confirm their phone model and iOS system version before installation to ensure that the eSIM function can be used normally.

Basic preparations before installation:

• Ensure your iPhone is updated to iOS 17, iOS 18, or the latest version;
• Connected to a stable Wi-Fi or mobile network;
• Have the eSIM QR code or activation link/code provided by your carrier ready;
• If it's an eSIM for travel, complete the purchase and data submission through the online store first.

iPhone eSIM Installation Steps

1. Install via QR Code

1. Open the "Settings" app on your iPhone, then go to "Cellular / Mobile Data";
2. Tap "Add eSIM / Add Cellular Plan";
3. Scan your eSIM QR code with the camera;
4. When "Cellular Plan Detected" appears on the screen, tap "Add (eSIM Add Plan)" and confirm installation;
5. After installation is complete, you can name this eSIM and set its default use (e.g., mobile data, voice, or data priority).

2. Manual Entry or Activation Code Installation

If you cannot scan the QR code, you can select "Enter Details Manually", enter the SM-DP+ address and activation code provided by the telecommunications provider, and then follow the on-screen prompts to complete the installation.

3. Quick Transfer eSIM (for two iPhones)

If you are transferring an eSIM from an old iPhone, you can use the "Quick Transfer" feature to allow the new device to actively retrieve the eSIM plan from the old device. This method is particularly suitable for retaining your original number when upgrading your phone.

Recommendations After Setup

After installing the eSIM, you can confirm whether it is activated in "Settings > Cellular" and set "Default Voice Number" and "Mobile Data Line" as needed. If you encounter issues such as iMessage or FaceTime not activating after installation, try restarting your iPhone or updating the settings according to Apple's official support guidelines.
