How to activate eSIM on your iPhone

SIM cards, those small but crucial components storing data in your mobile phones, often go unnoticed until the moment comes to remove them—whether you're upgrading to a new iPhone®, switching carriers, or preparing for international travel. You can also do these things if your phone is equipped with an eSIM (embedded Subscriber Identity Module). Not familiar with the technology? Don’t worry. We’ll explain.

Asurion Experts will walk you through all your tech setup, whether you have a new iPhone or want to turn on Apple® Stolen Device Protection. Here’s our guide to eSIM activation on your iPhone.

Fast fix

If your iPhone model supports eSIM and your carrier assigns you an eSIM when you purchase your plan, it will activate automatically when you set up your iPhone. 

What’s the difference between a SIM card and eSIM? 

A SIM card is a tiny, removable plastic part that stores data in your mobile phone and connects your device to your mobile network. 

An eSIM also stores your information and connects your device to your mobile network, but the technology is built-in and allows you to transfer data digitally rather than with a physical card.

Benefits of using eSIM over a traditional SIM card

Here are some of the benefits of eSIM technology:

Simplifies setup. 

You can activate a mobile plan digitally using eSIM technology—no need to swap out your old SIM card for a new one. 

Supports multiple plans. 

With eSIM, you can store multiple carrier profiles at once, making it easier to switch between cellular networks or maintain separate personal and business phone numbers. 

Increases security. 

The eSIM technology is embedded in your device, so there’s no card that could get lost, stolen, or damaged. 

Simplifies international travel. 

If you want to use a local carrier when traveling abroad eSIM lets you do so without swapping out a card. 

What you’ll need to use eSIM

Here’s what you’ll need to use eSIM on your iPhone:

• An iPhone XS, iPhone XS Max, iPhone XR, or later. 
• A wireless carrier or worldwide service provider that supports eSIM technology.  
• A Wi-Fi connection for earlier models. No Wi-Fi connection is needed with iPhone 14 and later. 
• An updated operating system.

Convert a SIM card to an eSIM on the same iPhone

1. On your iPhone, open Settings > Cellular. 
2. Tap Convert to eSIM. If you don’t see Convert to eSIM, your carrier doesn’t support this option. Contact your carrier to move your phone number from your physical SIM to an eSIM. 
3. Tap Convert Cellular Plan > Convert to eSIM. 
4. Your eSIM will activate. When activation is complete, your previous SIM card will be deactivated.
