This usually happens when you purchase a carrier-connected iPhone from Apple in the United States or from a carrier and you provide your cellular-plan details. If an eSIM was assigned to your iPhone when you bought it, turn on your iPhone and follow the instructions to activate your eSIM. Some carriers and worldwide service providers can assign a new eSIM to your iPhone, making setup easy. To activate your eSIM using eSIM Carrier Activation, eSIM Quick Transfer, or another activation method, turn on your iPhone and follow the instructions. If you purchased an iPhone 14 model or later in the United States, your iPhone activates with an eSIM.

If these options aren't available, contact your carrier to activate your eSIM using a QR code or your carrier's iPhone app. You can also use these options later to add or transfer an eSIM. Make sure that you’re signed in with your Apple ID on both devices, or make sure that your previous iPhone is unlocked, nearby with Bluetooth turned on, and using iOS 16 or later. Some carriers support transferring a phone number from your previous iPhone to your new iPhone without needing to contact them. With eSIM Quick Transfer, you transfer the SIM from your previous iPhone to your new iPhone without contacting your carrier. With either method, to activate your eSIM during setup, turn on your iPhone and follow the instructions. With eSIM Carrier Activation, your carrier assigns an eSIM to your iPhone when you purchase it.

You can activate your eSIM while you're setting up your iPhone if your carrier supports eSIM Carrier Activation or eSIM Quick Transfer.

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