Buying the iPhone 15? Here's how your carrier is handling eSIM transfers

If you're upgrading to iPhone 15 from iPhone 13 or earlier, here's how your wireless company will help you navigate one tricky issue.

This week, Apple announced its new iPhone 15, which, like last year's iPhone, forgoes the traditional physical SIM card for an eSIM. If you are upgrading from an iPhone that's at least two years old, it is likely that you will have to make to switch to the new data format.

The transition will vary depending on your carrier, whether it supports eSIM or not (most of them do), and what practices they have in place to facilitate the activation. Most carriers will link your phone number to the device when you order your iPhone, making the setup process as straightforward and simple as possible. Others, maybe not.

Here's how the three major US phone carriers -- Verizon, AT&T, and T-Mobile -- are supporting eSIM activation. 

Verizon

Verizon has an eSIM system in place that allows you to activate a phone in just a few steps. The process is especially easy if you purchase the phone from Verizon, of course. 

"If you purchased your iPhone from Verizon, or are a current Verizon customer, simply turn your phone on, follow the iPhone's setup steps, and you are good to go," Verizon tells ZDNET. 

If you are switching to Verizon, you'll first need to connect to Wi-Fi to start the activation process. Then, download the "My Verizon App" from the app store or visit the Verizon website to activate the eSIM. Utilizing the same app, you can switch from other carriers or upgrade your account without needing a physical SIM card.

AT&T

With AT&T, setting up your eSIM is similar. 

"AT&T makes it easy for customers to activate an eSIM if they're moving off an old phone or switching carriers. They can simply head to a store, visit ATT.com, or use the myAT&T app to set up and activate a new phone in minutes," AT&T tells ZDNET.

When switching from another carrier to AT&T and you're buying a new device, turn it on and follow the prompts to download your eSIM phone number. If you have an existing AT&T number and have a new iPhone, you can simply follow the setup prompts on the device.

T-Mobile

T-Mobile is currently running a Network Pass program, which allows you to take advantage of the carrier's unlimited data via eSIM for three months at no charge.

To participate in this trial, the only requirement is to have an unlocked eSIM-compatible phone, like the iPhone 15. This is a great way to get a feel for how eSIM works and whether or not it's a good fit for your lifestyle.

If you plan on purchasing the new iPhone, like the other carriers, you can activate your T-Mobile eSIM by connecting to Wi-Fi and following the setup process on-screen. You may be asked to enter your T-Mobile account information or phone number to receive your eSIM data.
