What is the difference between UICC and SIM?

UICC, or Universal Integrated Circuit Card, is the newer smart card technology that has replaced traditional SIMs in modern devices. SIM and UICC cards serve a similar purpose of identifying subscribers on mobile networks, but UICC offers enhanced functionality.

Firstly, a SIM card is single-application and can only operate on 2G networks, while a UICC is multi-application. It can hold both SIM and USIM applications to support both 2G GSM as well as 3G and 4G networks in one card.

Secondly, UICC cards have larger memory capacities than SIMs. They can store more data like contacts, messages, and profiles. This allows seamless transfers between devices while keeping all information synced.

Thirdly, UICC supports faster LTE network speeds for high-bandwidth applications and media. SIM cards bottleneck at slower 3G speeds.

Fourthly, UICC uses a more advanced global platform security model. It provisionally installs subscriber credentials through a certified Authority instead of the previous methods, which made SIMs vulnerable to cloning.

Lastly, UICC is specified by standards bodies, while SIM implementation was left to the manufacturers’ discretion. UICC ensures consistent cross-platform functionality and interoperability.
