What is a physical SIM card?

A physical SIM card (short for Subscriber Identity Module) is a small, removable plastic chip that typically inserts into a phone's SIM card tray. This is the type of SIM card we're most familiar with, storing user information like phone number and carrier data, and connecting the device to mobile networks. You can easily remove it and replace it with another SIM card when switching networks or traveling.

What is an eSIM?

An eSIM (embedded SIM) is an electronic SIM card built into a device's motherboard. Unlike a physical SIM card, an eSIM cannot be removed and is operated entirely through software. Users can quickly activate an eSIM by downloading a service pack via a QR code or a carrier app.

eSIMs are becoming increasingly popular on modern devices like the iPhone, Google Pixel, and the new Samsung Galaxy, and are ideal for international travelers due to their flexibility and ease of remote setup.
