3ชั้น

3ชั้น is a powerful Chrome extension developed by the Office of the NBTC designed to protect your mobile phone rights through a unique 3-tier audit report lock. The application allows users to check and monitor how many mobile lines are registered under their name, identify unauthorized usage, and prevent others from using their phone number without permission.

With 3ชั้น, users can securely lock or unlock their SIM registration by themselves directly within the app, providing an easy and informed way to safeguard their mobile phone identity and prevent fraud. This tool is essential for anyone wanting to maintain control over their mobile phone registrations and protect themselves from unauthorized SIM usage.
