What is Apple Universal Link? 

An Apple Universal Link is a type of URL or link that allows iOS apps to open specific content directly within the app itself, rather than in a web browser. If the app isn't installed, the link can redirect to a web page or the App Store to download the app. Universal Links use standard HTTP or HTTPS URLs that can be shared and used in other apps because they lead to a website URL.

How Universal Links simplify the eSIM activation process?

Universal Links simplify the eSIM activation process by automating several steps that would otherwise be manual:

1. Direct Activation: When you click a Universal Link provided by your eSIM carrier, it automatically directs your device to the eSIM activation screen.
2. Pre-filled Information: The link includes all necessary configuration details like the SM-DP+ Address and Activation Code, eliminating the need for you to enter them manually.
3. Instant Setup: This streamlined approach reduces setup time, allowing your eSIM to be activated almost instantly upon clicking the link.

This method enhances user convenience by making the activation of eSIMs straightforward and error-free.

Structure of the Universal Link

The link typically follows a structured format that includes a base URL, an indication of the provisioning method, and crucial activation parameters such as the SM-DP+ Address and the Activation Code.

1. Base URL: https://esimsetup.apple.com/esim_qrcode_provisioning - This is the standard URL used by Apple for eSIM provisioning.
2. Query Parameter: ?carddata= - This parameter is followed by the provisioning details.
3. Provisioning Details: LPA:1$SMDP+_Address$Activation_Code - LPA:1 signifies the method of eSIM provisioning. The SM-DP+ Address and the Activation Code are separated by a dollar sign ($).

Actual Format with Value

In this example:

• rsp.truphone.com is the SM-DP+ Address.
• JQ-209U6H-6I82J5 is the Activation Code, demonstrating the flexibility in character casing.

Important Notes for Implementation:

• URL Casing: The base URL should always be in lowercase to ensure compatibility and avoid errors in processing.
• Activation Code: The Activation Code may contain capital letters and should be entered exactly as provided.
• External Link Configuration: If integrating this link within an app, configure it to open externally. This ensures that the device’s browser handles the activation, adhering to Apple’s setup protocols.

FAQs about eSIM installation via Universal Link

What is a Universal Link for eSIM installation?

A Universal Link is a URL that automatically directs your Apple device to a configuration screen to install and activate an eSIM without needing manual data entry. It uses embedded details like the SM-DP+ Address and Activation Code.

Which Apple devices support eSIM installation via Universal Links?

Why is there no direct eSIM installation option for Android?

Android devices typically require users to manually enter eSIM details or use QR codes for activation, as there isn’t a standardized universal link method like Apple's. This approach is due to varying carrier implementations and a lack of a unified system for seamless eSIM provisioning across all Android devices.

If the eSIM installation fails:

• Check your internet connection and try again.
