SEIO Agent

SEIO Agent is a mobile authentication service app that powers your SKT USIM supplementary services, including NFC functionality, digital payments, and secure verification tools. This essential service application runs in the background to ensure your USIM-based features work seamlessly across your device.

Once installed, SEIO Agent enables critical services like mobile T-money payments, Cashbee digital wallet, PASS authentication, and other NFC-dependent applications to function properly. The app works silently behind the scenes—you won't interact with it directly, but your other apps depend on it to access USIM capabilities.

Keep SEIO Agent installed and active to maintain uninterrupted access to all your SKT supplementary services. If the app is removed or the service stops, your USIM authentication and digital payment features may fail. After installation, simply relaunch any app that uses USIM services like T-money or Cashbee, and SEIO Agent will activate automatically. For support, contact [email protected].
