what is esim in iphone

An eSIM is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical SIM card. It is an industry-standard digital SIM that is built into newer smartphones, including the iPhone XS, iPhone XS Max, iPhone XR, and later models. With eSIM, you can install eight or more eSIMs on an iPhone and use two phone numbers at the same time. To use eSIM on an iPhone, you need to have a wireless carrier that supports eSIM and a Wi-Fi connection. You can set up and activate your eSIM on an iPhone in different ways, but the most common is with a QR code. Some carriers and worldwide service providers can assign a new eSIM to your iPhone, making setup easy. If you purchased an iPhone 14 model or later in the United States, your iPhone activates with an eSIM.
