What is an eSIM?
An eSIM integrates the functions of a SIM card into a phone’s hardware, making it easier and quicker to change phone service. Using an eSIM can also make it easier to manage multiple phone services on one device.

These SIM cards look like small memory cards and usually slide into the side of your phone on a small tray.
Many of the best Android phones already offer the ability to use an eSIM, including those from Google and Samsung.
