Now that you know the benefits, let’s move to the main event: how to activate an eSIM on iPhone.

How to Activate an eSIM on iPhone: Step-by-Step Instructions

Activating an eSIM on your iPhone is a straightforward process, but it requires a few steps to ensure everything goes smoothly. Below, we’ll break down the process into simple stages. Whether you’re setting up a new iPhone or switching to an eSIM on your current device, this guide will help you master how to activate an eSIM on iPhone.

Step 1: Check If Your iPhone Supports eSIM

Not all iPhones support eSIM technology, so the first step in how to activate an eSIM on iPhone is to confirm your device is compatible. Apple introduced eSIM support with the iPhone XS, XS Max, and XR in 2018. Here’s a list of eSIM-capable iPhones as of 2025:

• iPhone XS, XS Max, XR
• iPhone 11, 11 Pro, 11 Pro Max
• iPhone 12, 12 mini, 12 Pro, 12 Pro Max
• iPhone 13, 13 mini, 13 Pro, 13 Pro Max
• iPhone 14, 14 Plus, 14 Pro, 14 Pro Max
• iPhone 15, 15 Plus, 15 Pro, 15 Pro Max
• iPhone 16, 16 Plus, 16 Pro, 16 Pro Max

To verify whether your iPhone is eSIM-compatible:

1. Go to Settings > General > About.
2. Scroll to the Carrier Lock section. If you see “No SIM restrictions” or eSIM details, your iPhone is eSIM-compatible.

If your iPhone doesn’t support eSIM, you’ll need to use a physical SIM card or upgrade to a newer model.

Step 2: Confirm Carrier Support for eSIM

The next step in how to activate an eSIM on iPhone is ensuring your carrier supports eSIM technology. Major U.S. carriers like AT&T, Verizon, and T-Mobile offer eSIM support, but it’s wise to double-check. If you’re outside the U.S., contact your carrier or visit their website to confirm eSIM availability.

Some carriers provide prepaid eSIM plans, ideal for travelers or those exploring eSIM options. Popular international eSIM providers include Airalo, Nomad, and Holafly.

Step 3: Obtain an eSIM Activation Code

To activate an eSIM, you’ll need an activation code from your carrier. This code typically comes in one of these formats:

• QR Code: A scannable code provided digitally or on a physical card.
• Activation Code: A string of letters and numbers you enter manually.
• Carrier App: Some carriers allow eSIM activation directly through their app.

Here’s how to get your eSIM activation code:

1. Contact Your Carrier: Visit the carrier’s website, call customer support, or visit a store to request an eSIM.
2. Buy a Plan: If using a third-party eSIM provider, purchase a plan online, and they’ll send a QR code or activation details.
3. Check Your Email: If setting up a new iPhone, your carrier may send eSIM details via email during the setup process.

Pro Tip: If switching from a physical SIM to an eSIM, ask your carrier to transfer your existing phone number to the eSIM to streamline how to activate an eSIM on iPhone.

Step 4: Start the eSIM Activation Process on Your iPhone

With your activation code ready, it’s time to dive into how to activate an eSIM on iPhone. Follow these steps:

1. Open Settings: Go to the Settings app on your iPhone.
2. Navigate to Cellular: Tap Cellular (or Mobile Data in some regions).
3. Add Cellular Plan: Tap Add Cellular Plan or Add eSIM. If you’re setting up a new iPhone, this option may appear during the initial setup.
4. Scan QR Code: If your carrier provided a QR code, use your iPhone’s camera to scan it. Ensure you’re connected to Wi-Fi or have a stable internet connection.
5. Enter Activation Code (If Necessary): If you received a manual activation code, tap Enter Details Manually and input the code provided by your carrier.
6. Follow On-Screen Instructions: Your iPhone will guide you through the remaining steps, such as accepting terms or verifying your phone number.

Step 5: Name Your eSIM Plan

If you’re using multiple SIMs (e.g., a physical SIM and an eSIM), naming your eSIM plan helps avoid confusion. Here’s how:

1. Go to Settings > Cellular.
2. Tap the eSIM plan you just added.
3. Tap Cellular Plan Label and select a label like “Personal,” “Business,” or “Travel.” You can also create a custom label.

This step is particularly helpful if you’re managing multiple numbers or plans, such as for work and personal use.

Step 6: Test Your eSIM Connection

After completing the steps for how to activate an eSIM on iPhone, test your connection:

1. Check Signal Bars: Look at the top-right corner of your iPhone’s screen to confirm signal bars.
2. Make a Test Call: Dial a friend or family member to ensure your eSIM is functional.
3. Test Data: Open a browser or app to verify your mobile data is active.

If everything works, congratulations—you’ve successfully activated your eSIM! If not, don’t panic—we’ll cover troubleshooting later in this guide.
