Comparison of eSIM and Physical SIM

How Does an eSIM Work?

An eSIM, or embedded Subscriber Identity Module card, is a digital version of the traditional physical SIM card that is used to activate and connect to a mobile network. Unlike a traditional SIM card that needs to be inserted into a slot or tray, an eSIM is built directly into the device itself. It stores all the necessary information required to identify and authenticate the user on the network, such as the network provider and the user’s phone number.

When a user wants to activate their device with an eSIM, they simply need to scan a QR code or manually enter the activation code provided by their network operator. This code contains all the necessary data required for the device to connect to the network. Once the code is entered, the eSIM will automatically download the network’s credentials and activate the device.

This process is quick and easy compared to the traditional method of physically inserting and activating a traditional SIM card. Additionally, eSIMs allow users to switch between different network providers without needing to physically change the SIM card, providing greater flexibility and convenience.
