What is UICC Unlock on your Sprint Device?

UICC stands for Universal Integrated Circuit Card. It is an innovative SIM (Subscriber Identification Module) card designed for smartphones and tablets compatible with high-speed networks.

The UICC is responsible for identifying you to your wireless carrier service so that your plan can work on your device. It can save your contacts and provides a secure, reliable and efficient data connection. It also enables global roaming and keeps providing new applications and services. When your phone is activated, like putting in a SIM or connecting to WiFi, UICC sends a signal to your wireless carrier to verify the identity of your phone. There are two types of SIM unlocking (UICC unlock and MSL unlock).

If your smartphone is locked in terms of SIM functions and cannot allow any other carrier service to run, it needs SIM unlocking. In this case, the device is restricted to only one carrier service through programming and cannot run any other wireless service. If you have bought a Samsung Sprint phone, your device falls in this category. You can opt for direct SIM unlock that allows various carrier services to run on the phone, both locally and internationally.

MSL stands for Master Subsidy Lock. In this case, your device is integrated with a disabling software that has an unlocking code. If your device was launched before Feb 2015, there is a high chance that it is equipped with MSL unlocking.
