iPhone 15 eSIM: How to transfer your phone number to Apple's new iPhone (2024)

Apple's release of theiPhone 14 lineuplast fall unveiled many new features for the iPhone, ranging from satellite connectivity to upgraded cameras and, most importantly, the switch to an eSIM-- a change that will likely be found in the new iPhone 15 lineup, too.

With the eSIM, instead of using a small plastic SIM card to transfer your phone number over to the iPhone, you use a non-physical SIM card that is embedded directly into the device. There isn't even a SIM card tray on the iPhone 14 at all; it just doesn't exist.

If you upgrade to the new iPhone 15, the process for converting your SIM card to an eSIM will vary, but the process is generally straightforward. Ahead of the iPhone 15 release, ZDNET explains what an eSIM is and walks you through how to set it up.

What is an eSIM?

A SIM card is used by phone makers and wireless carriers as a form of a handshake that lets the carrier know which phone you're using, and in turn, it tells your handset which phone number and carrier to use.

An eSIM, which is a digital version of the small plastic SIM card, can be programmed and reprogrammed as many times as required. Apple says iPhone eSIM users can store up to eight different eSIMs, which is handy if you frequently travel or have multiple business lines.

For the curious, eSIM stands for "embedded subscriber identity module."

How to set up your iPhone 15's eSIM

Setup for the iPhone 15 makes transitioning from a physical SIM to an eSIM a simple process. When you order your iPhone, your carrier and phone number are linked to that device. So, in theory, your iPhone 15 should come ready to go through the eSIM Carrier Activation process.

As Apple notes, "Setting up your eSIM is usually just a matter of turning on your new iPhone and following the onscreen instructions."

If you skipped past transferring your number over to your phone during the setup process, you can still transfer your number and eSIM to the iPhone 15. To do that, open theSettingsapp, then tapCellular>Set Up Cellularand follow the prompts.

What to do if you're switching from an Android phone

The process for switching from an Android phone with a physical SIM or eSIM to an iPhone 15 and eSIM will be a bit different than the process when switching from iPhone to iPhone and will vary depending on the carrier.

There is a possibility that your number was assigned an eSIM when you ordered your phone, and in that case, the process will be just as simple as described above.

However, if you aren't prompted to transfer your number to your phone during the initial setup process, you'll need to contact your carrier's customer service department to get a QR code or to request that they set up eSIM Carrier Activation.

Also:

"If you're switching to iPhone (from an Android phone, for example), contact your carrier to transfer your phone number to your iPhone through eSIM Carrier Activation or by scanning a QR code from your carrier," says Apple.

Once given a QR code, all you'll have to do is scan it using your iPhone to add your eSIM.

If your carrier sets up eSIM Carrier Activation instead, you will receive a notification that says, "Carrier Cellular Plan Ready to Be Installed," which you can then tap on to begin the process.
