What is UICC?

It stands for Universal Integrated Circuit Card (UICC). It is a modified version of a SIM (Subscriber Identification Module) card. UICC informs your data provider about your plans, secures your connection, and offers a multi-media network. It is a reliable model that can effortlessly work over network bands like 3G and 4G.

However, the android carrier company that provides UICC keeps it locked so you cannot add a different sim on your device. This limits the functionality of the UICC sim to only one operator.

For example, if a user opts for Sprint’s data pack on a UICC SIM for their phone or any other electronic device, Sprint locks UICC. This way, the user can only use Sprint as its sole network carrier; however, once UICC is unlocked, the restriction is lifted. UICC unlock allows you to access multiple networks on any device, not limiting you to one SIM card use.
