Balance Update / USSD blocker

Enjoy millions of the latest Android apps, games, music, movies, TV, books, magazines & more. Anytime, anywhere, across your devices.

IMPORTANT - This app does not work on Android 4.2.2 or later. The APIs used by this app have been removed in this version and later. (To check your Android version, see Settings > About Phone)

IMPORTANT - You MUST restart your phone after installing or updating the app. Also, please launch and configure the app to start blocking messages.

This is a free app and has no ads.

This app selectively blocks balance update messages that carriers send after each call, typically on prepaid plans. These balance update messages show as annoying popups after end of each call.

Technically, these balance update messages are USSD messages, and cannot be filtered by SMS blockers. Hence, this app specializes in blocking USSD messages.

You may choose to block messages that contain a specific string (substring match), or a list of keywords (comma separated keyword list), or advanced users can specify regular expressions that when matched trigger blocking.

You can also choose to show the balance update message once per day (or week/month). This will cause the first balance update message to show up, and all other messages will be blocked for the rest of the day.

Last 25 messages are saved in the message log, along with indication if the message was blocked or allowed.

If you encounter an issue, please make sure you have restarted the phone after installation. Please email me if that does not resolve the issue.

Technical users - this app actually doesn't need READ_PHONE_STATE permission. I've added it so that Android doesn't auto update this app from 1.0 to 1.2, as that requires a restart.
