Embedded SIM, also known as eSIM, is a SIM card that can be programmed into a phone without inserting it manually. It functions similarly to a standard SIM card but does not require a physical card and can only be used on devices that have eSIM compatibility pre-installed.

It doesn’t have the eSIM; there is no eSIM compatibility pre-installed on this phone. The Poco M4 5G is a hybrid-SIM smartphone, which means that the user can only use removable SIM cards.
