What is UICC on your device?

 A SIM card is a type of electrical device called a universal integrated circuit card (UICC). By using pre-configured according to the norms on a SIM card, it is responsible for assisting your smartphone in connecting with wireless provider services. The UICC handles your device’s connection to the network and identification therein. Additionally, it protects your data and contacts to offer a dependable, secure, and efficient data connection.

The current generation of SIM cards, known as UICC (Universal Integrated Circuit Cards), supports GSM and UMTS-enabled handsets. The UICC is configured as a SIM application while your smartphone is linked to a GSM network (which is what most people are familiar with), and your smartphone runs a USIM app when it is connected to a UMTS network.

Furthermore, data services and other value-added activities are monitored by UICC. The UICC goes into operation and sends a message to your cellular carrier provider to confirm the identity of the mobile after you activate your phone for the first time using a SIM card. By locking the UICC, a smartphone may occasionally be forced to use a particular cellular provider’s connection. This indicates you are unable to use another SIM card in your phone unless you unlock your UICC.
