How to Add eSIM on iPhone: Step-by-Step Guide

Adding an eSIM to your iPhone can be confusing if you haven't done it before. Many developers and tech enthusiasts want to understand how to activate and manage eSIMs on iPhones for testing or personal use. This guide solves the problem by walking you through the entire process of adding an eSIM on your iPhone.

An eSIM is a digital SIM that allows you to activate a cellular plan without a physical SIM card. Developers use eSIMs to test multiple carrier profiles or manage dual SIM functionality on iPhones. This article explains how to add an eSIM on iPhone, including prerequisites, setup steps, troubleshooting, and best practices.

What prerequisites are required for adding an eSIM on iPhone?

• Compatible iPhone model: You need an iPhone XS, XR, or newer model that supports eSIM functionality.
• iOS version: Ensure your iPhone runs iOS 12.1 or later, as eSIM support was introduced in this version.
• Carrier support: Your mobile carrier must support eSIM activation and provide a QR code or activation details.
• Internet connection: A stable Wi-Fi or cellular connection is required to activate the eSIM profile.
• Apple ID and password: For some carriers, you may need to sign in to your Apple ID during activation.

How do you add an eSIM on iPhone?

Adding an eSIM on iPhone involves scanning a QR code or entering details manually to activate the cellular plan digitally. The process is done through the iPhone's Settings app.

To add an eSIM, open Settings, go to Cellular, then tap Add Cellular Plan. You can scan the QR code provided by your carrier or enter the details manually. After activation, the eSIM will appear as a secondary line in your cellular settings.

This method allows you to use dual SIM functionality, with one physical SIM and one eSIM active simultaneously.

How do you manually enter eSIM details on iPhone?

If your carrier does not provide a QR code, you can manually enter the eSIM information. This includes the SM-DP+ address and activation code provided by your carrier.

In Settings, under Cellular, tap Add Cellular Plan, then choose Enter Details Manually. Input the SM-DP+ address and activation code exactly as given. This method is useful for carriers that provide activation info via email or app rather than QR code.

After entering the details, your iPhone will download and activate the eSIM profile. You can then assign labels and configure settings for the new cellular plan.

What are common eSIM activation errors on iPhone and how do you fix them?

• Invalid QR code or activation code: Double-check the QR code or manual details for typos. Contact your carrier if the code is expired or incorrect.
• No cellular plan found: Ensure your carrier supports eSIM and your iPhone is compatible. Restart your device and try again.
• Activation failed due to network issues: Confirm you have a stable internet connection during activation. Switch to Wi-Fi if cellular data is unreliable.
• eSIM not showing after activation: Restart your iPhone. If the problem persists, remove the eSIM profile and try adding it again.
• Carrier restrictions: Some carriers require you to activate eSIM through their app or website. Follow carrier-specific instructions.
