Dash is a free Android app developed by UCC Works B.V. that helps you keep track of your mobile data usage. With this app, you can monitor your data usage in detail, including both in and out-of-bundle usage.

The app also provides information on when your new data bundle will start and how much data you have consumed in the current month. Additionally, it offers a feature called Visual Voicemail that allows you to easily and quickly listen to and delete voicemail messages. You can also call back contacts who have left you a voicemail message and record your personal greeting.

To log in to the app, you will need to use your provider's portal login credentials. If you don't have them or have forgotten them, you will need to contact your mobile provider.

Overall, Dash is a great tool for anyone who wants to keep track of their mobile data usage and stay on top of their bills.
