Krone mobile Tarif is a free Android app that provides users with easy access to their mobile account consumption, cost status, invoices, and itemized bills from the last few months. Developed by A1 Telekom Austria AG, the app also offers users personalized settings to optimize their tariff at any time by activating additional packages or upgrading their units.

With Krone mobile Tarif, users can have an overview of the costs incurred in the current billing period and the remaining free units (data volume, minutes, SMS) in the current billing period. They can also display recent bills and itemized bills, change tariffs, activate additional packages, and manage multiple SIM cards using the group function.
