The SLT Broadband Usage Checker is an unofficial Chrome extension designed to provide users with a quick and secure method to monitor their Sri Lanka Telecom (SLT) broadband usage. With this tool, users can access their data consumption details directly from the browser toolbar without the need for a separate login, as it utilizes existing MySLT Portal authentication.

Key features include comprehensive data views of Main Pack, Extra GB, Bonus Data, and more, presented with visual progress bars for easy understanding. The extension allows for auto-refreshing of data every hour and provides the ability to manually refresh whenever needed. Users can also quickly re-login to the MySLT portal if their session expires, ensuring seamless access to updated information while maintaining privacy and security.
