How to Change an eSIM on iPhone: A Definitive Guide

So, you’re looking to swap out your eSIM on your iPhone, eh? You’ve come to the right place. Whether you’re traveling abroad, switching carriers, or simply want to manage your data plans more efficiently, understanding how to change your eSIM on an iPhone is crucial. It’s generally a straightforward process, but can seem intimidating if you’ve never done it before. Here’s the lowdown.

The easiest and most common way to change your eSIM is through the Settings app. Navigate to Settings > Cellular > Add eSIM. You’ll typically have three options: Transfer from Nearby iPhone, Use QR Code, or Enter Details Manually. Choose the option that best suits your situation. Follow the on-screen prompts to activate your new eSIM. That’s the gist of it, but stick around – there’s a lot more to unpack here.

Diving Deeper: Activating Your New eSIM

Let’s break down those options and explore some nuances.

Transfer from Nearby iPhone

This is the smoothest option if you’re upgrading to a new iPhone or simply have another iPhone with an active eSIM you want to move. Both iPhones need to be running iOS 16 or later and be in close proximity. Here’s the step-by-step:

1. On your new iPhone, go to Settings > Cellular > Add eSIM.
2. Select Transfer from Nearby iPhone.
3. Follow the prompts on both iPhones to authenticate and transfer the eSIM profile. This may involve verifying a code displayed on both screens.
4. Your old eSIM will be deactivated on the original iPhone, and the new eSIM will be activated on your target iPhone.

Scanning a QR Code

Many carriers provide a QR code to activate your eSIM. This is probably the most common method when getting a new plan. Here’s how to use it:

1. Go to Settings > Cellular > Add eSIM.
2. Select Use QR Code.
3. Scan the QR code provided by your carrier using your iPhone’s camera.
4. Your iPhone will detect the eSIM profile and guide you through the activation process. This might involve confirming your cellular plan and setting your preferred line for calls, texts, and data.

Pro Tip: If you don’t have access to a physical QR code, some carriers allow you to access it via their app or website. You can then screenshot the QR code and upload it by tapping “Enter Details Manually” then choosing the “Photos” option when prompted.

Entering Details Manually

This option is used when you don’t have a QR code and your carrier provides you with specific activation details, such as an SM-DP+ Address and an Activation Code.

1. Go to Settings > Cellular > Add eSIM.
2. Select Enter Details Manually.
3. Enter the SM-DP+ Address and Activation Code provided by your carrier.
4. Follow the on-screen instructions to complete the activation process.

Important Note: Be extremely careful when entering these details. Incorrect information can prevent your eSIM from activating. If you’re unsure, contact your carrier for assistance.

Managing Multiple eSIMs

One of the beauties of eSIM technology is the ability to have multiple profiles stored on your iPhone. This is incredibly useful for frequent travelers or individuals who need separate lines for personal and business use.

To manage your eSIMs, go to Settings > Cellular. You’ll see a list of your active and inactive eSIMs. You can then:

• Toggle between eSIMs: Simply select the eSIM you want to use for calls, texts, and data.
• Label your eSIMs: Give each eSIM a descriptive name (e.g., “Business Line,” “Travel SIM”) to easily identify them.
• Remove an eSIM: If you no longer need an eSIM, you can remove it by tapping on it and selecting “Remove eSIM.” Be cautious, as removing an eSIM is permanent unless you have a backup!

Troubleshooting Common eSIM Issues

Sometimes, things don’t go as planned. Here are a few common issues and how to address them:

• eSIM Activation Failed: Double-check that you’ve entered the correct information (QR code or manual details). Restart your iPhone. If the issue persists, contact your carrier.
• No Cellular Service: Ensure that the correct eSIM is selected for cellular data in Settings > Cellular. Check your carrier’s network status in your area.
• eSIM Not Showing Up: Restart your iPhone. If the eSIM still doesn’t appear, try resetting your network settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings). Warning: This will erase your Wi-Fi passwords.
• QR Code Not Scanning: Make sure the QR code is clear and well-lit. Try adjusting the distance between your iPhone and the QR code. If all else fails, request the activation details (SM-DP+ Address and Activation Code) from your carrier.
