About U+ USIM
U+ USIM is a system agent that strengthens the stability and security of your USIM service. This essential background utility works seamlessly with your mobile carrier's authentication library to ensure reliable performance of USIM-dependent features.
The app functions as a critical support component for mobile services. Without this agent installed, you may experience errors or interruptions when using mobile payment cards, mobile credit services, and other USIM-secured transactions. It operates quietly in the background, requiring no direct user interaction.
After installation, restart any related USIM service applications on your device to ensure proper integration and functionality. For Optimus LTE users with LU6200 devices, upgrading to the latest OS version is recommended before installing U+ USIM.
This is not a standalone application with a visible interface—it's a foundational service component that protects your mobile carrier services and payment security. Keep U+ USIM installed to maintain uninterrupted access to all USIM-based features.
