An eSIM is a digital SIM card built into your device. Instead of inserting a physical SIM, you can download a mobile plan and activate it instantly by scanning a QR code.

Most recent smartphones support eSIM technology, including newer iPhone, Samsung Galaxy, Google Pixel, and many other flagship devices. Check your device specifications to confirm eSIM compatibility before purchasing.
