If you encountered this APK through a tutorial or forum promising "free GSM unlocking" or "network info hacks," understand that such content is often malicious. Protecting your device and personal data should always come before any claimed functionality.

The tool is opened on a Samsung device via a browser or hidden menu launch, often using commands found on XDA Developers forums .

Many applications request broad permissions that could compromise your privacy. Without clear information on what GSM.one.info.apk requires in terms of permissions, users might inadvertently grant access to sensitive data.

If you tell me the genuine goal (e.g., "I want to unlock my Samsung phone’s network" or "I need to check signal strength"), I can guide you to safe, verified methods or official apps.
