What Is eSIM on iPhone?

An eSIM is an embedded SIM — a reprogrammable chip that’s built into your iPhone during manufacturing. Like a physical SIM, an eSIM identifies you as a mobile subscriber and gives you access to a carrier’s network.

The difference is that an eSIM works 100% digitally. There’s no need to remove or insert a SIM card to stay connected. Instead, you can install an eSIM profile on your iPhone and instantly connect to a mobile network.

Which iPhones Have eSIM?

The first Apple phones to support eSIM technology were the iPhone XS, iPhone XS Max, and iPhone XR, released in 2018. iPhones released since have been equipped with a SIM tray and eSIM, with the exception of the eSIM-only iPhone 14 in the United States.*

You can jump into your iPhone’s settings to find out if it’s eSIM-compatible. Here’s how:

• Go to Settings > General > About.
• Scroll down to Available SIM (iOS 15 or later) or Digital SIM (earlier iOS versions).
• If your phone supports eSIMs, you’ll see a 15-digit IMEI number.

*Whether your device is eSIM-compatible depends on your mobile carrier and the country or region where you purchased your iPhone. If you aren’t sure, we recommend contacting your provider to find out.

How Many eSIMs Can iPhone Have?

You can install up to eight eSIM profiles on most iPhones and have two active simultaneously. Dual SIM technology makes this possible and allows you to use more than one SIM and/or eSIM at a time.

With a Dual SIM iPhone, you can:

• Add a local eSIM plan to stay connected when you travel.
• Use one plan for voice and another for data.
• Keep separate business and personal numbers on the same phone.

How To Set Up eSIM on iPhone

There are three ways to set up an eSIM on iPhone:

• Use the Quick Transfer method to convert your existing SIM to an eSIM.
• Use the Carrier Activation method to activate a new eSIM from your carrier.
• Install an eSIM from a third-party provider (like Airalo!) for travel.

In this section, we’ll give you step-by-step instructions for each one.

Quick Transfer: Convert SIM to eSIM

You can use Apple’s Quick Transfer method if you’re midway through a mobile contract and want to convert your physical SIM to an eSIM. Here’s how to do it:

• Go to Settings > Cellular.
• Tap Convert to eSIM (if you don’t see this option, your carrier doesn’t support converting a SIM to an eSIM).
• Tap Convert Cellular Plan.
• Tap Convert to eSIM.
• Wait for your eSIM to activate.
• Remove your physical SIM (it will deactivate when the eSIM activates).
• Restart your iPhone.

Carrier Activation: Activate a New eSIM

Starting a new service agreement with a mobile provider? Your provider can use Apple’s eSIM Carrier Activation method to assign an eSIM to your iPhone. Here’s how it works.

If you’re purchasing a new iPhone:

• Turn on your iPhone.
• Follow the step-by-step instructions to install an eSIM.

If you already have an iPhone:

• Scan the QR code provided with your service agreement.
• Follow the steps to install an eSIM.

If your new agreement replaces the plan on your physical SIM card, remove it and restart your iPhone to connect your eSIM.

Install an eSIM from Airalo

You can also buy and install an eSIM from a third-party provider like Airalo. This option’s your best bet if you’re planning a trip and want to stay connected abroad.

Airalo is an eSIM marketplace that provides affordable eSIM plans for 200+ countries and regions worldwide. You can purchase a plan, install an eSIM on your iPhone, and instantly connect to a mobile network at your destination.

Your iPhone must be carrier-unlocked to install an eSIM from a third-party provider. You can contact your carrier or follow these steps to find out if your iPhone is unlocked:

• Go to Settings > General > About.
• Scroll down to view the Carrier Lock section.
• If your device is unlocked, it will show “No SIM restrictions.”

If your iPhone is eSIM-compatible and carrier-unlocked, you’re all set to purchase an eSIM from Airalo! Here’s how to get started:

• Visit the Airalo website.
• Buy an eSIM for your destination.
• Follow the step-by-step installation instructions.

When To Remove an eSIM From iPhone

If your eSIM plan has expired and you don’t have plans to return to the destination, you can deactivate it to remove it from your iPhone. Here’s how to do it:

• Go to Settings.
• Tap Cellular or Mobile.
• Tap your eSIM line.
• Select Remove Mobile Data Plan (it may say “Remove eSIM” or “Delete Mobile Plan,” depending on your device).

Some eSIMs can only be installed once, so you’ll want to be absolutely sure you don’t need to use the eSIM again before deactivating it.
