An eSIM, or embedded SIM, is a digital SIM card that allows you to activate a mobile plan from your carrier without the need for a physical SIM card. With an eSIM, you can install multiple SIM profiles on your iPhone and use multiple phone numbers simultaneously. It is a standard industry technology that provides flexibility and convenience for users [[SOURCE 1]].
Requirements for using eSIM on iPhone
To use an eSIM on your iPhone, you will need the following:
- iPhone XS, iPhone XS Max, iPhone XR, or later models.
- A mobile network operator or service provider that offers eSIM service.
- The new iPhone must be connected to a Wi-Fi network.
- Please note that eSIM for iPhone is not available in mainland China. However, it is supported in Hong Kong and Macao, with some iPhone models. For using dual SIM with two nano-SIM cards in mainland China, Hong Kong, and Macao, please refer to the specific guidelines provided by Apple [[SOURCE 1]].
How to set up an eSIM on iPhone
Setting up an eSIM on your iPhone is a straightforward process. Here are the general steps:
- Turn on your new iPhone and follow the on-screen instructions. Usually, during the initial setup, you will have the option to activate or transfer your eSIM.
- If your carrier supports eSIM activation or quick transfer, you can activate it while setting up your iPhone. The activation process may vary depending on your carrier.
- If your carrier offers quick transfer, you can transfer the SIM from your previous iPhone to the new one without contacting the carrier. Make sure both devices are signed in with the same Apple ID, and the previous iPhone is unlocked, nearby with Bluetooth enabled, and running iOS 16 or later.
- If the above options are not available, you can contact your carrier to activate the eSIM using a QR code or the carrier's iPhone app.
- For iPhone models from iPhone 14 and later that only support eSIM, they can be activated without a Wi-Fi network [[SOURCE 1]].
Allowing the carrier to activate eSIM on iPhone
In some cases, carriers and service providers can assign a new eSIM to your iPhone, making the setup process more convenient. This typically happens when you purchase an iPhone connected to a carrier in the United States or when you acquire it through a carrier and provide your mobile plan details. If your iPhone comes with an assigned eSIM, you can follow the on-screen instructions to activate it [[SOURCE 1]].
Using quick transfer of eSIM on iPhone
Some carriers offer the option to transfer the SIM from your previous iPhone to the new one without contacting them. You can also convert your current physical SIM card to an eSIM. Here's how:

- If you need to transfer the eSIM but cannot access your current iPhone, contact your carrier for assistance.

Transferring physical SIM or eSIM to eSIM after setup
If you want to transfer the physical SIM or eSIM from your previous iPhone to the new iPhone after the initial setup, you can follow these steps:
