What is the difference between eSIM and eUICC?

eSIM and eUICC are often used seemingly interchangeably, even though there is a difference between the two: the eSIM is the hardware component of the SIM and a physical form that can be soldered into a solution. The eUICC is the software component that allows the remote SIM provisioning of multiple network profiles.

What is the difference between UICC and eUICC?

UICC is the more common one at the moment, as it supports GSM/2G, 3G, 4G, and 5G. eUICC is an enhancement upon UICC and is the new standard in SIM cards. Alongside supporting all of the previously supported connectivity options, eUICC cards also support multiple carriers on the same device.
