eSIM

eSIM is a virtual SIM card that allows you to use data roaming services provided by telecom operators without the need to replace a physical SIM card. You can install up to two eSIM profiles on your phone and use them simultaneously.

Setting up eSIM usually just requires opening the camera on your iPhone, scanning a QR code, and following the installation instructions. It's important to note that the installation process needs to be done in an environment with internet access.
