In recent years, Apple has steadily moved away from traditional physical SIM cards in favor of eSIM technology—a built-in digital SIM that allows users to activate cellular plans without inserting a physical SIM card. The eSIM offers more flexibility, better support for dual SIM functionality, and a cleaner design for iPhones. If you’ve recently purchased an iPhone or switched carriers, you may be asking: How do I activate eSIM on my iPhone?
This in-depth guide walks you through everything you need to know about eSIM activation on your iPhone—step-by-step instructions, troubleshooting tips, carrier requirements, and how to switch from a physical SIM to eSIM. Whether you’re activating a new number or converting your existing SIM, this article has got you covered.
What is an eSIM?
An eSIM (Embedded Subscriber Identity Module) is a digital version of the traditional SIM card. Instead of physically inserting a chip into your device, the eSIM is embedded inside your iPhone’s motherboard and can be programmed via software to connect to your carrier’s network.
Key Benefits of Using eSIM:
- No need for a physical SIM card
- Supports Dual SIM (eSIM + physical SIM or two eSIMs on newer models)
- Convenient switching between networks or plans
- Faster activation, especially for international travel
- Cleaner design without a SIM tray (on eSIM-only models like iPhone 14/15 US)

Most iPhones released in the past few years support eSIM. Here’s a breakdown:
✅ eSIM + Physical SIM Support:
- iPhone XS, XS Max

- iPhone 13 series
- iPhone SE (2nd and 3rd gen)

Note: Non-U.S. versions of iPhone 14/15 still include a SIM tray in most regions.
Before You Begin: Check These First

How to Activate eSIM on iPhone (Step-by-Step)
There are several ways to activate an eSIM depending on your carrier and situation. Let’s go through the most common methods:
Method 1: Activate eSIM Using QR Code (Most Common)
This is the most popular method provided by carriers worldwide.

- Tap Use QR Code
- Scan the QR code provided by your carrier
- Follow the on-screen prompts to complete the setup
- Once done, you may be asked to restart your device
After activation, the eSIM will appear as a new cellular plan in your settings.
Method 2: Activate eSIM Manually Using Details
If you didn’t get a QR code, your carrier might provide you with manual activation details like the SM-DP+ address and activation code.
🔹 Steps:

- Tap Enter Details Manually
- Enter the SM-DP+ address and Activation Code provided by your carrier
- Tap Next and follow prompts
This method is handy if you’re activating via online chat or customer support.

If you already use a physical SIM and want to go digital, many carriers allow conversion right from your iPhone.
🔹 Steps:
- Go to Settings > Cellular > Convert to eSIM
- Tap Convert Cellular Plan
- Confirm your selection
- Wait while your iPhone activates the eSIM
- The physical SIM will deactivate automatically
Not all carriers support this feature, so check with your provider before proceeding.

Some carriers offer their own apps to activate your eSIM directly.
🔹 Steps:
- Download your carrier’s app from the App Store
- Log in using your account details
- Select the option to set up a new plan or eSIM
- Follow the prompts to activate eSIM
This is commonly used by prepaid or international carriers.
How to Use Dual SIM with eSIM on iPhone

🔹 To set up dual SIM:
- Add a second plan via eSIM using one of the methods above
- Go to Settings > Cellular
- Customize each line (e.g., “Personal” and “Business”)
- Choose which line is used for:
- Calls and messages

You can easily switch between plans without removing any SIM cards.
