embedded-SIM (eSIM)

An eSIM is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical SIM.

An embedded-SIM (eSIM) or embedded universal integrated circuit card (eUICC) is a form of programmable SIM card that is embedded directly into a device.

In system to system (M2M) applications where there is no requirement to change the SIM card, this avoids the requirement for a connector, improving reliability and security. An eSIM can be provisioned remotely; end-users can add or remove operators without the need to physically swap a SIM from the device.
