How to Activate eSIM on iPhone 15: A Step-by-Step Guide

Activating eSIM on your iPhone 15 is a breeze! In just a few steps, you can switch from a physical SIM card to an embedded SIM and enjoy all the benefits of a dual-SIM device. This handy feature allows you to have two phone numbers on a single iPhone, perfect for separating work and personal life, or for having a local and international number while traveling.

Step by Step Tutorial: How to Activate eSIM on iPhone 15

Before we dive into the steps, let’s understand what we’re aiming for. Activating your eSIM means you’re setting up your iPhone 15 to use a digital SIM card provided by your carrier, instead of the traditional physical SIM card. This gives you the flexibility to have multiple plans on a single device.

Step 1: Check Carrier Compatibility

Make sure your carrier supports eSIM on iPhone 15.

Not all carriers support eSIM, so it’s crucial to verify that yours does. You can easily do this by visiting your carrier’s website or contacting their customer service.

Step 2: Get an eSIM Activation Plan

Obtain an eSIM activation plan from your carrier, which could be a QR code, a carrier app, or an activation code.

Depending on your carrier, you’ll receive a QR code to scan, a carrier app to download from the App Store, or an activation code that you’ll need to enter manually.

Step 3: Go to Cellular Settings

Open the Settings app and tap on ‘Cellular’.

In the Cellular settings, you’ll find options to set up and manage your SIM cards, both physical and eSIM.

Step 4: Add Cellular Plan

Tap on ‘Add Cellular Plan’ and use your iPhone camera to scan the QR code or enter the details manually.

If you have a QR code, the camera will open automatically. Line up the code within the frame to scan. For manual setup, you’ll enter the details provided by your carrier.

Step 5: Label Your Plans

Label your eSIM plan (like ‘Personal’ or ‘Business’) to differentiate it from your physical SIM.

This step is particularly useful if you’re using dual SIMs, as it helps you identify which number is which.

Step 6: Set Default Line

Choose a default line for calls and messages, or use both lines based on your preference.

You can pick a number for calls and texts, or have both numbers active. This is especially handy for managing work and personal calls.

Step 7: Confirm Activation with Carrier

Make sure your eSIM is activated by confirming with your carrier if necessary.

Some carriers might require you to call or use their app to finalize the activation process. Ensure you follow their instructions to start using your eSIM.

After completing these steps, your iPhone 15 will now be using an eSIM. You can start making calls, sending texts, and using data with your new digital SIM card. This means you can easily switch between different carriers or plans without needing to physically swap out SIM cards – a huge advantage for frequent travelers or those who like to keep their options open.

  • Double-check with your carrier about any potential charges for using eSIM, especially when roaming.
